X40421 Product details

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

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; or 250µA from VBATT.
Fault detection register.
Selectab.
