DS50002300A-page 20 2014 Microchip Technology Inc. UCS81003 EVALUATION BOARD USER'S GUIDE Chapter 3. Hardware Description 3.1 UCS81003 DEVICE The UCS81003 provides a single USB port power switch for precise control of up to 3.0A continuous current (2.85A typical) with overcurrent limiting, dynamic thermal management, latch/auto-recovery upon fault, selectable active low or high enable, under and overvoltage lockout, and back-drive protection. USB Charging Port profiles are integrated into the UCS81003 to assure compliance to multiple standards. In addition to power switching and USB Charging Port profiling, the UCS81003 provides automatic and configurable USB data line handshaking to enable charging of USB-IF Battery Charging 1.2 (CDP or DCP modes), Chinese Telecommunications Industry Standard YD/T 1591-2009, Apple(R) Inc., RIM(R) and many other mobile devices. The UCS81003 provides a device attachment detection output, as well as a dedicated alert output, with current monitoring, charge rationing for controlled delivery of current regardless of a host's power state. When the limit is reached, the UCS81003 will perform the user-programmed behavior (report and disconnect is the default). 3.2 EVALUATION BOARD POWER SOURCE The UCS81003 has split power supply support: * VS is the voltage input to Power Switch. This supply rail is required to charge the portable device. VS source is selected by populating a jumper on J5 header, as follows: Jumper Position Definition 1-2 VS is supplied from the external 5V power supply connected to J1 power jack. 2-3 VS is supplied from the VBUS pin of the J3 USB connector. Use this option only if the USB host port can supply the charging current for the portable device. * VDD is the power supply for chip functionality. The UCS81003 Evaluation Board contains two additional ICs, MCP2221 USB bridge and MCP23018 I/O expander, which are also powered from the VDD supply rail. VDD source is selected by populating a jumper on the J4 header, as follows: Jumper Position Definition 1-2 VDD is supplied from VBUS pin of the J2 USB connector. When using the board in this configuration and the Attach Detection feature of the UCS81003 is used, the VS voltage must not exceed VDD + 150 mV, as specified in the data sheet. 2-3 VDD is connected to VS. This configuration is recommended when using the Attach Detection feature. If the board is evaluated with a PC running the GUI, then the VS must be supplied after the USB cable is plugged into the J2 connector. 2014 Microchip Technology Inc. DS50002300A-page 21 UCS81003 Evaluation Board User's Guide 3.3 MCP2221 USB-TO-SMBUS BRIDGE The MCP2221 is a USB-to-UART/I2C bridge that supports SMBus communication. It is controlled through USB interface by the GUI running on the PC. It is the master device on the SMBus/I2C bus. It is used to read and write the registers of the two devices connected to the SMBus/I2C interface: UCS81003 and MCP23018 I/O expander. 3.4 MCP23018 I/O EXPANDER MCP23018 is a 16-bit I/O Expander with open-drain outputs and I2C interface. Its I2C address is configured to 0100_000(R/W), different than all possible addresses of the UCS81003. The I/O pins used in this application are configured as inputs. They are used to read the logic state of the following UCS81003 pins: ALERT#, ADET#, PWR_EN, EM_EN, M1, M2. 3.5 DIRECT SMBUS CONNECT OPTION It is also possible to connect an external SMBus master to the UCS81003 Evaluation Board. Remove the jumpers on J7 and connect the SMBus master to the header pins that are linked directly to UCS81003 pins SMDATA/LATCH and SMCLK/S0. Note that ground must be connected to one of the test point grounds or header pins on the EVB. See Figure 3-1 for header pins description. USB bridge SCL pin USB bridge SDA pin SMCLK/S0 UCS81003 pin SMDATA/LATCH UCS81003 pin Ground FIGURE 3-1: DS50002300A-page 22 UCS81003-to-SMBus Bridge Jumpers. 2014 Microchip Technology Inc.

It affects the speed that the software reads the registers, but will not affect the device's sampling time. The default is 25 ms. This number can range from 0 to 5000 ms in increments of 25 ms. 4.2.1.5 SINGLE/CONTINUOUS READ The panel defaults to continuous register reads (toggle switch in down position, as shown in Figure 4-2). To stop continuous register reads, check the "Single Read Enable" box. In order to capture the register values at a given time, click the switch, which will briefly flip to Single Read. 4.2.1.6 DEFAULT When this button is pressed, it loads the defaults to all registers of the UCS81003. 4.2.1.7 STEP When selected, Step will go through the Emulation Profiles in sequence, from Legacy 1 through 7, then BC1.2 DCP, and finally Custom. The actual DCE cycle is slightly different, please see product's data sheet for more information. 4.2.1.8 DEMO The Demo button enables an automated routine to cycle through a user-defined set of profiles and selects the highest current profile. This feature emulates an external controller and is not part of the UCS81003 device. DS50002300A-page 26 2014 Microchip Technology Inc. Software Description 4.2.2 Pin State and Attach Status Panel The Pin State & Attach Status section on the right side of the GUI, shown in Figure 4-4, provides a quick graphical status reference and allows physical control pin override. This section is always displayed. ALERT# and A_DET# Indicators Pin Indicators Pin Override Check Boxes FIGURE 4-4: Pin State and Attach Status. 4.2.3 Pin State & Attach Status Panel 4.2.3.1 ALERT# AND A_DET# INDICATORS When the ALERT# and A_DET# indicators are green, the signals at the device's respective pin are low and the corresponding condition has occurred (alert or device attached, respectively). When the indicators are dark, the pin states are high. 4.2.3.2 PIN INDICATORS The pin indicators (SEL, PWR_EN, M1, M2 and EM_EN) shown in Figure 4-4 are green if the signal on the corresponding pin on the UCS81003 device is high, and dark if the signal is low. If the "Pin Ignore" box is checked (see Section 4.2.3.3 "Pin Override"), these indicators will reflect the GUI overrides for these pins. 4.2.3.3 PIN OVERRIDE For evaluation convenience, the GUI can override the setting of the following pins on the UCS81003 device: PWR_EN, M1, M2 and EM_EN. Check the "Pin Ignore" box (see Figure 4-4) to enable pin override. Then, check in the corresponding pin box to set the value high. Note 1: Pin override does not affect the actual signal on the pin. It only affects the register values. 2: The SEL pin is only read once by the UCS81003 at power up, so there is no pin override for it. To close the port power switch, the PWR_EN state must match the SEL state (e.g., SEL = high and PWR_EN = high). 2014 Microchip Technology Inc. DS50002300A-page 27 UCS81003 Evaluation Board User's Guide 4.2.4 Active Mode Selection The Active Mode Selection section on the right side of the GUI, shown in Figure 4-5, provides a quick reference regarding operating state based on the values of M1, M2 and EM_EN.

Software Description 4.3 TAB DESCRIPTIONS 4.3.1 Main Tab The Main tab (Figure 4-6) shows key parameters related to the port power switch, including the maximum current limit, the present current limit (always equal to or less than maximum current limit), and power state (e.g. detect, active, error, etc.). When a portable device has been successfully attached, the screen shows the power state change from Detect to Active and shows the various handshakes applied. Once it is determined that the device is charging, the screen shows which emulation profile was successful, and the graph shows the charging current. Optionally, the user may monitor the charge delivered or ration the charge delivered to the attached device. Tab Selection Status Panel Instantaneous Current Measurement Screen Measured Current Status Right-click Wave Box for Plot Appearance Settings FIGURE 4-6: Current Status Main Tab Window Overview. 4.3.1.1 DEDICATED CHARGER EMULATION (DCE) CYCLE As shipped, the UCS81003 is ready to function as a dedicated charger, which will be applied when there is an attach detection. To view this behavior, perform the following: 1. Connect VS to the evaluation board (see Section 2.4 "Jumpers on the Evaluation Board"). The VS_LOW indicator on the bottom of the Main Tab must be dark. If the color is red, the voltage is not high enough to charge a portable device. 2. Connect a portable device to the board. Use the OEM USB charging cable that comes with the portable device. 3. The UCS81003 should detect an attachment, switch to the Active Power state, apply an emulation profile and deliver a charge. Figure 4-7 shows the interface after charging has started. 2014 Microchip Technology Inc.

Disconnect the portable device from the board. The UCS81003 should detect a removal, switch to the Detect power state, and stop delivering a charge. Figure 4-8 shows the interface after a removal was detected. Power State Indicator Changed Disconnect Point showing in Plot A_DET# Pin Status is deasserted FIGURE 4-8: DS50002300A-page 30 Main Tab - Removal Detected. 2014 Microchip Technology Inc. Software Description 4.3.1.2 CHARGING DOWNSTREAM PORT (CDP) The CDP charging profile is based on the "USB Battery Charging Specification v1.x". When a BC1.x-compliant portable device attachment is detected, the UCS81003 and the portable device do handshaking based on the standard. If handshaking is successful, charging occurs up to the set current limit. To select the CDP port power profile, M1, M2 and EM_EN must all be high. This can be done by removing the jumpers for these pins (from J9 header) or by using the pin override in the GUI (see Section 4.2.3.3 "Pin Override"). 4.3.1.3 PASS-THROUGH Data Pass-Through does not apply any type of charger emulation. When selected, it closes the USB high-speed data switch and supplies current up to the current limit. To select Data Pass-Through, M1, M2 and EM_EN can be set to any one of the two DATA PASS-THRU combinations (010 and 110), as shown in Figure 4-9. This can be done by setting the jumpers for these pins (from J9 header - see Section 2.4 "Jumpers on the Evaluation Board") or by using the pin override in the GUI (see Section 4.2.3.3 "Pin Override"). Data Pass-Through Options FIGURE 4-9: 4.3.1.4 Data Pass-Through Selection Options. CURRENT MONITORING AND CHARGE RATIONING To view current monitoring and current rationing, perform the following on the Main tab: 1. Set a Ration Limit. The ration limit is expressed in mAh (electric charge). 2. Set rationing behavior. The Ration Completion Behavior defaults to "Report & Disconnect". Once the ration limit is reached, portable device charging will cease, the ALERT# pin will assert, and the Ration Complete bit will be set. If you do not want the system to behave in this fashion, select one of the other three options from the Ration Completion Behavior drop-down list: Report, Report & Sleep or Take No Action. 3. Connect VS to the evaluation board (see Section 2.4 "Jumpers on the Evaluation Board"). The VS_LOW indicator on the bottom of the Main Tab must be dark. If the VS_LOW indicator is red, the voltage is not high enough to charge a portable device. 4. Connect a portable device to the evaluation board. Use the OEM USB charging cable that comes with the portable device. 5. Enable rationing by checking the Ration Enable check box on the Main Tab. 6. Watch the GUI as the device starts charging. Figure 4-10 shows the interface after the ration limit was reached (for "Report & Disconnect" behavior setting). 2014 Microchip Technology Inc. DS50002300A-page 31 UCS81003 Evaluation Board User's Guide Note: Ration Enable As shown in Figure 4-10, the green trace is the instantaneous current, while the red diagonal line is the charge being delivered in mAh.
