XC6124E749MR-G

Supervisors Overview

The XC6124E749MR-G is a high-precision, low current consumption voltage detector with watchdog function and ON/OFF control. It incorporates CMOS process technology and consists of a reference voltage source, delay circuit, comparator, and output driver. The detect voltage is internally fixed at 7.4V using laser trimming technology. Six watchdog timeout periods are available in a range from 50ms to 1.6s. Five release delay times are available in a range from 3.13ms to 400ms. The operating voltage range is 1.6V to 5.0V.
