This page provides the datasheet information for the X40435, a member of the X40430 Triple Voltage Monitor family.

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.
