X40421 - Dual Voltage Monitor

Download the X40421 datasheet PDF. This datasheet also covers the X40420 variant, as both devices belong to the same dual voltage monitor family and are provided as variant models within a single manufacturer datasheet.

Description

The X40420/21 combines power-on reset control, watchdog timer, supply voltage supervision, and secondary supervision, manual reset, and Block Lock™ protect serial EEPROM in one package.

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

Features

  • Monitor Voltages: 5V to 1.6V Memory Security Battery Switch Backup VOUT 5mA to 50mA Preliminary Datasheet 4kbit EEPROM X40420/X40421.
