XC6124A536ER-G

Supervisors Overview

The XC6124A536ER-G is a high-precision voltage detector with a watchdog function manufactured by Torex Semiconductor. It operates within a supply voltage range of 1 V to 6 V and features an N-channel open-drain output. The device monitors a single input channel with a fixed threshold voltage of 3.6 V, determined by internal laser trimming. It includes a built-in delay circuit for release timing and supports watchdog timeout periods ranging from 50 ms to 1.6 s. The component functions reliably across an operating temperature range of -40°C to +85°C and consumes low quiescent current.
