MAX6832 - Ultra-Low-Voltage SC70 Voltage Detectors and uP Reset Circuits

General Description

The MAX6832

MAX6840 are microprocessor (µP) supervisory circuits used to monitor low-voltage power supplies in µP and digital systems.

They provide excellent circuit reliability and low cost by eliminating external components and adjustments when used with +1.2V to +1.8V powered circuits.

Key Features

  • o Factory-Set Reset Threshold Voltages for Nominal Supplies from 1.2V to 1.8V o Low Power Consumption: 7.5µA (typ) o Space-Saving 3- and 4-Pin SC70 Packages o ±2.5% Reset Threshold Accuracy Over Temperature o Five Different Timeout Periods Available: 70µs (voltage detector), 1.5ms, 30ms, 210ms, and 1.68s o Three Reset Output Configurations Push-Pull RESET Push-Pull RESET Open-Drain RESET o Guaranteed Reset Valid to VCC = 0.55V.
  • Active-Low 0.75V.
  • Active-High o Adjustable Threshold R.

MAX6832–MAX6840 Ultra-Low-Voltage SC70 Voltage Detectors and µP Reset Circuits General Description The MAX6832–MAX6840 are microprocessor (µP) supervisory circuits used to monitor low-voltage power supplies in µP and digital systems. They provide excellent circuit reliability and low cost by eliminating external components and adjustments when used with +1.2V to +1.8V powered circuits. These devices assert a reset signal whenever the VCC supply voltage declines below a preset threshold or whenever manual reset (MR) is asserted. Reset remains asserted for a fixed timeout delay after VCC has risen above the reset threshold or when manual reset is deasserted. Five different timeout periods are available: 70µs (voltage detector), 1.5ms, 30ms, 210ms, and 1.68s.
