Quad Voltage Up and Down Sequencer

and Monitor with Programmable Timing

ADM1186

FEATURES

GENERAL DESCRIPTION

Powered from 2.7 V to 5.5 V on the VCC pin

The ADM1186-1 and ADM1186-2 are integrated, four-channel

Monitors four supplies via 0.8% accurate comparators

Digital core supports up and down supply sequencing

Multiple devices can be cascaded (ADM1186-1)

Four inputs can be programmed to monitor different voltage

levels with resistor dividers

Capacitor programmable supply sequence time delays

and a timeout delay to 5% accuracy at 25°C

Four open-drain enable outputs

voltage monitoring and sequencing devices. A 2.7 V to 5.5 V

power supply is required on the VCC pin for power.

Four precision comparators, VIN1 to VIN4, monitor four

voltage rails. All four comparators share a 0.6 V reference and

have a worst-case accuracy of 0.8%. Resistor networks that are

external to the VIN1, VIN2, VIN3, and VIN4 pins set the

undervoltage (UV) trip points for the monitored supply rails.

The ADM1186-1 and ADM1186-2 have four open-drain enable

outputs, OUT1 to OUT4, that are used to enable power supplies.

An open-drain power-good output, PWRGD, indicates whether

the four VINx inputs are above their UV thresholds.

Open-drain power-good output

Open-drain sequence complete pin and bidirectional

open-drain fault pin (ADM1186-1 only)
