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. By choosing 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 (typ) and 6-lead SC70 packaging, the parts are suitable for low-power portable applications. Table 1. Selection Table

Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
ESD CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although this product features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality.

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. ADM1085/ADM1086 Truth Table
VIN VTH_RISING >VTH_RISING ENIN 0 1 0 1 ENOUT 0 0 0 1
When VIN reaches the upper threshold voltage (VTH_RISING), an internal circuit generates a delay (tEN) before the enable output is asserted. If VIN drops below the lower threshold voltage (VTH_FALLING), the enable output is deasserted immediately. 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).
CAPACITOR-ADJUSTABLE DELAY CIRCUIT
Figure 20 shows the internal circuitry used to generate the time delay on the enable output. 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 de-asserting, 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.

OPEN-DRAIN AND PUSH-PULL OUTPUTS
The ADM1085 and ADM1087 have open-drain output stages that require an external pull-up resistor to provide a logic-high voltage level. The geometry of the NMOS transistor enables the output to be pulled up to voltage levels as high as 22 V.
VCC (22V)
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.

ADM1085/ADM1086/ADM1087/ADM1088 APPLICATION INFORMATION
SEQUENCING CIRCUITS
The ADM1085/ADM1086/ADM1087/ADM1088 are compatible with voltage regulators and dc-to-dc converters that have active-high or active-low enable or shutdown inputs, with a choice of open-drain or push-pull output stages. 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/dc converters and ADM1085s are connected in 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/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.

DUAL LOFO SEQUENCING
A power sequencing solution for a portable device, such as a PDA, is shown in Figure 27. This solution requires that the microprocessor's 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). 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. For the display power sequencing, the ADM1085 is equipped with capacitor C2, which creates the delay between the microprocessor and display power turning on. 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.

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's signal, so that it is enabled after the north bridge.

QUAD-SUPPLY POWER GOOD INDICATOR
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-ANDed together to make a quad-supply Power Good indicator.

SEQUENCING WITH FET SWITCHES
The open-drain outputs of the ADM1085 and ADM1087 can drive external FET transistors, which can switch on powersupply rails. All that is needed is a pull-up resistor to a voltage source that is high enough to turn on the FET.
