X40434 - Triple Voltage Monitor

Download the X40434 datasheet PDF. This datasheet also covers the X40430 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 X40430, X40431, X40434, X40435 combines power-on reset control, watchdog timer, supply voltage supervision, second and third voltage supervision, manual reset, and Block Lock™ protect serial EEPROM in one package.

Features

  • Monitoring voltages: 5V to 9V.
  • Independent core voltage monitor.
  • Triple voltage detection and reset assertion.
  • Standard reset threshold settings. See selection table on page 2.
  • Adjust low voltage reset threshold voltages using special programming sequence.
  • Reset signal valid to VCC = 1V.
  • Monitor three separate voltages.
  • Fault detection register.
  • Selectable power-on reset timeout (0.05s, 0.2s, 0.4s, 0.8s).
  • Sel.
