The devices contain a 400-m current-limited P-channel MOSFET that can operate over an input voltage range of 1.62 V to 5.5 V. Current is prevented from flowing when the MOSFET is off. The switch is controlled by an on/off input (ON), which is capable of interfacing directly with low-voltage control signals. The TPS2294x includes thermal shutdown protection that prevents damage to the device when a continuous over-current condition causes excessive heating by turning off the switch. When the switch current reaches the maximum limit, the TPS22941/2/3/4/5 operates in a constant-current mode to prohibit excessive currents from causing damage. TPS22941/3 has a current limit of 40 mA and TPS22942/4/5 has a current limit of 100 mA. For the TPS22941/2/5, if the constant current condition still persists after 10ms, these parts shut off the switch and pull the fault signal pin (OC) low. The TPS22941/2/5, have an auto-restart feature that turns the switch on again after 80 ms if the ON pin is still active. A current limit condition on the TPS22943 and on the TPS22944 immediately pull the fault signal pin low (OC pin) and the part remains in the constant-current mode until the switch current falls below the current limit.

Typical Application Circuit, Active-High Enabled Device (TPS22943, TPS22944 and TPS22945 Only) On/Off Control The ON pin controls the state of the switch. Activating ON continuously holds the switch in the on state as long as there is no fault. An undervoltage on VIN or a junction temperature in excess of 150C overrides the ON control to turn off the switch. ON is active high and has a low threshold, making it capable of interfacing with low-voltage signals. Undervoltage Lockout The undervoltage lockout turns off the switch if the input voltage (VIN) drops below the undervoltage lockout threshold. With the ON pin active, the input voltage rising above the undervoltage lockout threshold causes a controlled turn-on of the switch, which limits current overshoots. Thermal Shutdown Thermal shutdown protects the part from internally or externally generated excessive temperatures. During an overtemperature condition the switch is turned off. The switch automatically turns on again if the temperature of the die drops below the threshold temperature. Reverse Voltage If the voltage at the VOUT pin is larger than the VIN pin, large currents may flow and can cause permanent damage to the device. TPS2294x is designed to control current flow only from VIN to VOUT. Fault Reporting When an overcurrent, input undervoltage, or overtemperature condition is detected, OC is set active low to signal the fault mode. OC is an open-drain MOSFET and requires a pullup resistor between VIN and OC. During shutdown, the pulldown on OC is disabled, reducing current draw from the supply. Current Limiting When the switch current reaches the maximum limit, the TPS22921/2/3/4/5 operates in a constant-current mode to prohibit excessive currents from causing damage. TPS22921/3 has a current limit of 40 mA and TPS22922/4/5 has a current limit of 100 mA. A current limit condition immediately pulls the fault signal pin low (OC pin), and the part remains in the constant-current mode until the switch current falls below the current limit. Input Capacitor To limit the voltage drop on the input supply caused by transient in-rush currents when the switch turns-on into a discharged load capacitor or a short-circuit, a capacitor needs to be placed between VIN and GND. A 1-F ceramic capacitor, CIN, placed close to the pins is usually sufficient. Higher values of CIN can be used to further reduce the voltage drop.

This capacitor will prevent parasitic board inductances from forcing VOUT below GND when the switch turns off. For the TPS2294x, the total output capacitance needs to be kept below a maximum value, COUT(max), to prevent the part from registering an over-current condition and turning-off the switch. The maximum output capacitance can be determined from the following formula, COUT = ILIM(MAX) x tBLANK(MIN) / VIN Due to the integral body diode in the PMOS switch, a CIN greater than COUT is highly recommended. A COUT greater than CIN can cause VOUT to exceed VIN when the system supply is removed. This could result in current flow through the body diode from VOUT to VIN. Power Dissipation During normal operation as a switch, the power dissipation is small and has little effect on the operating temperature of the part. The parts with the higher current limits will dissipate the most power and that will only be, P = (ILIM)2 x rON = (0.2)2 x 0.4 = 16 mW when VIN= 5.5 V If the part goes into current limit the maximum power dissipation will occur when the output is shorted to ground. For TPS22941/2/5, the power dissipation scales by the auto-restart time (tRESTART) and the overcurrent blanking time (tBLANK) so that the maximum power dissipated is: P(max) = (tBLANK / (tRESTART + tBLANK)) x (VIN(max)) x ILIM(max) = (10 / (80 + 10) x 5.5 x 0.2 = 122 mW When using the TPS22943 and TPS22944, a short on the output causes the part to operate in a constant current state, dissipating a worst-case power as calculated above until the thermal shutdown activates. It then cycles in and out of thermal shutdown so long as the ON pin is active and the short is present. Board Layout For best performance, all traces should be as short as possible. To be most effective, the input and output capacitors should be placed close to the device to minimize the effects that parasitic trace inductances may have on normal and short-circuit operation. Using wide traces for VIN, VOUT, and GND will help minimize parasitic electrical effects along with minimizing the case to ambient thermal impedance. 14 Submit Documentation Feedback Copyright (c) 2008-2009, Texas Instruments Incorporated Product Folder Link(s): TPS22941 TPS22942 TPS22943 TPS22944 TPS22945 PACKAGE OPTION ADDENDUM www.ti.com 13-Nov-2009 PACKAGING INFORMATION Orderable Device Status (1) Package Type Package Drawing Pins Package Eco Plan (2) Qty TPS22941DCKR ACTIVE SC70 DCK 5 3000 Green (RoHS & no Sb/Br) CU NIPDAU Level-1-260C-UNLIM TPS22942DCKR ACTIVE SC70 DCK 5 3000 Green (RoHS & no Sb/Br) CU NIPDAU Level-1-260C-UNLIM TPS22942DCKRG4 ACTIVE SC70 DCK 5 3000 Green (RoHS & no Sb/Br) CU NIPDAU Level-1-260C-UNLIM TPS22943DCKR ACTIVE SC70 DCK 5 3000 Green (RoHS & no Sb/Br) CU NIPDAU Level-1-260C-UNLIM TPS22944DCKR ACTIVE SC70 DCK 5 3000 Green (RoHS & no Sb/Br) CU NIPDAU Level-1-260C-UNLIM TPS22945DCKR ACTIVE SC70 DCK 5 3000 Green (RoHS & no Sb/Br) CU NIPDAU Level-1-260C-UNLIM TPS22945DCKRG4 ACTIVE SC70 DCK 5 3000 Green (RoHS & no Sb/Br) CU NIPDAU Level-1-260C-UNLIM Lead/Ball Finish MSL Peak Temp (3) (1) The marketing status values are defined as follows: ACTIVE: Product device recommended for new designs. LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. (2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability information and additional product content details. TBD: The Pb-Free/Green conversion plan has not been defined. Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes. Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above. Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material) (3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
