X40031 - Triple Voltage Monitor

Download the X40031 datasheet PDF. This datasheet also covers the X40030 variant, as both devices belong to the same triple voltage monitor family and are provided as variant models within a single manufacturer datasheet.

Description

The X40030, X40031, X40034, X40035 combine power-on reset control, watchdog timer, supply voltage supervision, second and third voltage supervision, and manual reset, in one package.

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

Features

  • Triple voltage detection and reset assertion.
  • Standard reset threshold settings see selection table on page 5.
  • Adjust low voltage reset threshold voltages using special programming sequence.
  • Reset signal valid to VCC = 1V.
  • Monitor three seperate voltages.
  • Fault detection register.
  • Selectable power on reset timeout (0.05s, 0.2s, 0.4s, 0.8s).
  • Selectable watchdog timer interval (25ms, 200ms, 1.4s or off).
  • Debounced manua.
