X40020 - Dual Voltage Monitor

Description

The X40020 combines power-on reset control, watchdog timer, supply voltage supervision, and secondary supervision, and manual reset, in one package.

This combination lowers system cost, reduces board space requirements, and increases reliability.

Features

  • Dual voltage detection and reset assertion.
  • Three standard reset threshold settings (4.6V/2.9V, 4.6V/2.6V, 2.9V/1.6V).
  • VTRIP2 programmable down to 0.9V.
  • Adjust low voltage reset threshold voltages using special programming sequence.
  • Reset signal valid to VCC = 1V.
  • Monitor two voltages or detect power fail.
  • Battery switch backup.
  • VOUT: 5mA to 50mA from VCC; 250µA from VBATT.
  • Fault detection register.
  • Selectable.
