X40015S8I-A

Volt Supervisor Monitor 2.6V to 5V 8Pin SOIC

DESCRIPTION

The X40010/11/14/15 combines power-on reset control, watchdog timer, supply voltage supervision, and secondary voltage supervision, in one package. This combination lowers system cost, reduces board space requirements, and increases reliability.
