MAX16165 - 4-Channel Sequencer and Superviso

General Description

The MAX16165/MAX16166 monitor up to five voltages and sequence up to four voltages.

These devices provide an adjustable delay as each supply is turned on as well as monitor each power-supply voltage, including the input voltage VDD.

Key Features

  • 2.7V to 16.0V Wide Operating Voltage Range.
  • Monitor Up to Five Voltages.
  • Sequence Up to Four Voltages.
  • Power-Off in Reverse Order or Simultaneously.
  • Unlimited Daisy-Chain.
  • Capacitor-Adjustable Sequencing Delay.
  • Capacitor-Adjustable Power-Good Timeout.
  • Resistor-Configurable Power-Supply On and Off Thresholds.
  • Open-Drain (MAX16165)/Push-Pull (MAX16166) Outputs.
  • POK Output for System Microcontroller Reset.

Highly Integrated, 4-Channel Sequencer and Supervisor MAX16165/MAX16166 General Description The MAX16165/MAX16166 monitor up to five voltages and sequence up to four voltages. These devices provide an adjustable delay as each supply is turned on as well as monitor each power-supply voltage, including the input voltage VDD. The MAX16165/MAX16166 operate from a supply range of 2.7V to 16V and have an internal regulator output (ABP), power internal circuits, and supply more than 1mA additional current to any external circuitry. The sequencing is enabled by two inputs, ON and OFF. A rising edge on the ON input initiates power-on sequencing of the channels whereas a falling edge on OFF input initiates power-off sequencing.
