MAX6420 - Single/Dual-Voltage uP Reset Circuits

General Description

The MAX6412

MAX6420 low-power microprocessor supervisor circuits monitor system voltages from 1.6V to 5V.

These devices are designed to assert a reset signal whenever the VCC supply voltage or RESET IN falls below its reset threshold or the manual reset input is asserted.

Key Features

  • Monitor System Voltages from 1.6V to 5V.
  • Capacitor-Adjustable Reset Timeout Period.
  • Manual Reset Input (MAX6412/MAX6413/MAX6414).
  • Adjustable Reset Input Option (MAX6415.
  • MAX6420).
  • Dual-Voltage Monitoring (MAX6418/MAX6419/MAX6420).
  • Low Quiescent Current (1.7μA, typ).
  • 3 RESET Output Options.
  • Push-Pull RESET.
  • Push-Pull RESET.
  • Open-Drain RESET.
  • Guaranteed Reset Valid to VCC = 1V.

MAX6412–MAX6420 Low-Power, Single/Dual-Voltage μP Reset Circuits with Capacitor-Adjustable Reset Timeout Delay General Description The MAX6412–MAX6420 low-power microprocessor supervisor circuits monitor system voltages from 1.6V to 5V. These devices are designed to assert a reset signal whenever the VCC supply voltage or RESET IN falls below its reset threshold or the manual reset input is asserted. The reset output remains asserted for the reset timeout period after VCC and RESET IN rise above the reset threshold and the manual reset input is deasserted. The reset timeout is externally set by a capacitor to provide more flexibility. The MAX6412/MAX6413/MAX6414 feature fixed thresholds from 1.575V to 5V in approximately 100mV increments and a manual reset input.
