XC6123C731MR-G

Supervisors Overview

The XC6123C731MR-G is a high-precision voltage monitor with an integrated watchdog timer manufactured by Torex Semiconductor. It operates within a supply voltage range of 1.0 V to 6.0 V and detects input voltages from 1.6 V to 5.0 V. The device features a CMOS open-drain output and monitors one input channel. Key electrical parameters include a threshold voltage of 3.1 V, a reset delay time of 50 ms, and a typical static current consumption of 5 uA. It functions reliably across an operating temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a high-precision voltage detector with a built-in watchdog timer for system supervision
• Features low current consumption suitable for battery-powered applications
• Includes an enable pin to independently control the watchdog function while maintaining voltage detection

Supervisors Applications

• Microprocessor watchdog monitoring and reset circuits
