MAX16050 Voltage Monitor/Sequencer Circuit

Analog Devices' easy-to-use, power-up/power-down, sequencer/monitor for various applications

Image of Analog Devices' MAX16050 Voltage Monitor/Sequencer CircuitAnalog Devices' MAX16050 monitors up to 5 voltages and sequences up to 4 voltages. It provides an adjustable delay as each supply is turned on and also monitors each power-supply voltage, including the input voltage VCC. When all the voltages reach their final values and the reset delay timer expires, a power-on-reset (active-low RESET) output de-asserts allowing the microcontroller (MCU) to operate. If any voltage falls below its threshold, the reset output asserts and all voltage supplies are turned off. The MAX16050 can be daisy-chained to control a higher number of voltages in a system.

Features
  • Monitors up to 5 voltages/sequence up to 4 voltages

  • 2.7 V to 16 V operating voltage range
  • Charge pump to fully enhance external n-channel FETs
  • Capacitor-adjustable sequencing delay
  • Fixed or capacitor-adjustable reset timeout
  • Internal 85 mA pulldowns for discharging capacitive loads quickly
  • Daisy-chaining capability to communicate across multiple devices
  • Small 4 mm x 4 mm, 28-pin TQFN package
