GENERAL DESCRIPTION The ADM1085/ADM1086/ADM1087/ADM1088 are simple sequencing circuits that provide a time delay between the enabling of voltage regulators and/or dc-dc converters at powerup in multiple supply systems. When the output voltage of the first power module reaches a preset threshold, a time delay is initiated before an enable signal allows subsequent regulators to power up. Any number of these devices can be cascaded with regulators to allow sequencing of multiple power supplies. Threshold levels can be set with a pair of external resistors in a voltage divider configuration. With appropriate resistor values, the threshold can be adjusted to monitor voltages as low as 0.6 V. The ADM1086 and ADM1088 have push-pull output stages, with active high (ENOUT) and active low (ENOUT) logic outputs, respectively. The ADM1085 has an active-high (ENOUT) logic output; the ADM1087 has an active-low (ENOUT) output. Both the ADM1085 and ADM1087 have open-drain output stages that can be pulled up to voltage levels as high as 22 V through an external resistor. This level-shifting property ensures compatibility with enable input logic levels of different regulators and converters. All four models have a dedicated enable input pin that allows the output signal to the regulator to be controlled externally. This is an active high input (ENIN) for the ADM1085 and ADM1086, and an active low input (ENIN) for the ADM1087 and ADM1088. The Simple Sequencers are specified over the extended -40C to +125C temperature range. With low current consumption of 15 A (typical) and 6-lead SC70 packaging, the parts are suitable for low-power portable applications. Table 1.

A | Page 8 of 16 ADM1085/ADM1086/ADM1087/ADM1088 CIRCUIT INFORMATION TIMING CHARACTERISTICS AND TRUTH TABLES The enable outputs of the ADM1085/ADM1086/ADM1087/ ADM1088 are related to the VIN and enable inputs by a simple AND function. The enable output is asserted only if the enable input is asserted and the voltage at VIN is above VTH_RISING, with the time delay elapsed. Table 5 and Table 6 show the enable output logic states for different VIN/enable input combinations when the capacitor delay has elapsed. The timing diagrams in Figure 18 and Figure 19 give a graphical representation of how the ADM1085/ADM1086/ADM1087/ADM1088 enable outputs respond to VIN and enable input signals. Table 5.

A 250 nA current source charges a small internal parasitic capacitance (CINT). When the capacitor voltage reaches 1.2 V, the enable output is asserted. The time taken for the capacitor to reach 1.2 V, in addition to the propagation delay of the comparator, constitutes the enable timeout, which is typically 35 s. To minimize the delay between VIN falling below VTH_FALLING and the enable output deasserting, an NMOS transistor is connected in parallel with CINT. The output of the voltage detector is connected to the gate of this transistor so that, when VIN falls below VTH_FALLING, the transistor switches on and CINT discharges quickly. Table 6. ADM1087/ADM1088 Truth Table VIN Similarly, if the enable input is disabled while VIN is above the threshold, the enable output deasserts immediately. Unlike VIN, a low-to-high transition on ENIN (or high-to-low on ENIN) does not yield a time delay on ENOUT (ENOUT). VCC VTH_FALLING CINT ENIN tEN VTH_RISING CEXT Figure 20.

If VIN drops below the lower threshold voltage (VTH_FALLING), the enable output is deasserted immediately. Figure 19. ADM1087/ADM1088 Timing Diagram Rev.

The geometry of the NMOS transistor enables the output to be pulled up to voltage levels as high as 22 V. The ADM1086 and ADM1088 have push-pull (CMOS) output stages that require no external components to drive other logic circuits. An internal PMOS pull-up transistor provides the logic high voltage level. ADM1086/ADM1088 VCC (22V) VCC ADM1085/ADM1087 LOGIC 04591-026 04591-027 LOGIC Figure 22. Push-Pull Output Stage Figure 21.

Figure 23 to Figure 25 illustrate how each of the ADM1085/ADM1086/ ADM1087/ADM1088 simple sequencers can be used in multiple-supply systems, depending on which regulators are used and which output stage is preferred. In Figure 23, three ADM1085s are used to sequence four supplies on power-up. Separate capacitors on the CEXT pins determine the time delays between enabling of the 3.3 V, 2.5 V, 1.8 V, and 1.2 V supplies. Because the dc-to-dc converters and ADM1085s are connected in a cascade, and the output of any converter is dependent on that of the previous one, an external controller can disable all four supplies simultaneously by disabling the first dc-to-dc converter in the chain. For power-down sequencing, an external controller dictates when the supplies are switched off by accessing the ENIN inputs individually. 12V 3.3V DC/DC OUT 3.3V EN 3.3V IN DC/DC OUT ENABLE CONTROL OUT ENIN IN DC/DC OUT 1.2V 3.3V VCC VIN ENOUT ADM1085 CEXT EN 1.8V VCC VIN ENOUT ADM1085 ENIN DC/DC 3.3V VCC VIN EN 2.5V 3.3V 3.3V IN ENOUT ADM1085 CEXT ENIN CEXT 12V 3.3V 2.5V 1.8V 1.2V tEN1 tEN2 tEN3 EXTERNAL DISABLE Figure 23.

This solution requires that the microprocessor power supply turn on before the LCD display turns on, and that the LCD display power-down before the microprocessor powers down. In other words, the last power supply to turn on is the first one to turn off (LOFO). The enable output can drive multiple enable or shutdown regulator inputs simultaneously. 12V SD 9V SYSTEM POWER SWITCH SD 3.3V MICROPROCESSOR POWER ENOUT 12V ENIN CEXT SD 1.8V Figure 28. Enabling a Pair of Regulators from a Single ADM1085 POWER GOOD SIGNAL DELAYS Sometimes sequencing is performed by asserting power good signals when the voltage regulators are already on, rather than sequencing the power supplies directly. In these scenarios, a simple sequencer IC can provide variable delays so that enabling separate circuit blocks can be staggered in time. For example, in a notebook PC application, a dedicated microcomputer asserts a power good signal for North BridgeTM and South BridgeTM ICs. The ADM1086 delays the South Bridge signal, so that it is enabled after the North Bridge. 5V POWER_GOOD EN DISPLAY POWER ADM1086 ENIN CEXT 3.3V C2 VIN SYSTEM POWER 9V ENOUT EN ADM1086 ENIN VC1 CEXT Figure 29.

When the system is powered down, the ADM1085 turns off the display power immediately, while the 3.3 V regulator waits for C1 to discharge to 0.4 V before switching off. 9V ADP3333 3.3V An RC network connects the battery and the SD input of the ADP3333 voltage regulator. This causes power-up and powerdown transients to appear at the SD input when the battery is connected and disconnected. The 3.3 V microprocessor supply turns on quickly on power-up and turns off slowly on powerdown. This is due to two factors: Capacitor C1 charges up to 9 V on power-up and charges down from 9 V on power-down, and the SD pin has logic high and logic low input levels of 2 V and 0.4 V. SD ADP3333 2.5V 3.3V IN ADM1085/ADM1086/ADM1087/ADM1088 QUAD-SUPPLY POWER GOOD INDICATOR SEQUENCING WITH FET SWITCHES The enable output of the Simple Sequencers is equivalent to an AND function of VIN and ENIN. ENOUT is high only when the voltage at VIN is above the threshold and the enable input (ENIN) is high as well. Although ENIN is a digital input, it can tolerate voltages as high as 22 V and can detect if a supply is present. Therefore, a simple sequencer can monitor two supplies and assert what can be interpreted as a power good signal when both supplies are present. The outputs of two ADM1085s can be wire-AND'ed together to make a quadsupply power good indicator. The open-drain outputs of the ADM1085 and ADM1087 can drive external FET transistors that can switch on power supply rails. All that is needed is a pull-up resistor to a voltage source that is high enough to turn on the FET. 12V 3.3V VIN ENOUT ADM1085 3.3V 9V VIN ENOUT POWER_GOOD 2.5V ADM1085 5V Figure 31.
