XC6124C630MR-G

Supervisors Overview

The XC6124C630MR-G is a high-precision voltage detector with watchdog function manufactured by Torex Semiconductor Ltd. It operates within a supply voltage range of 1 V to 6 V and features an open-drain output configuration. The device monitors a single input channel with a fixed detection threshold of 3.0 V. It incorporates a built-in delay circuit for release timing and supports manual reset control via the EN/ENB pin. The component is designed for surface mount installation in SOT-25-5 packages and functions reliably across an operating temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer function with selectable timeout periods ranging from 50 ms to 1.6 s.
• Features an ON/OFF control pin (EN/ENB) that allows disabling the watchdog while maintaining voltage monitoring.
• Utilizes laser trimming technology to ensure high accuracy in detection voltage settings.
• Provides low current consumption suitable for battery-powered applications.

Supervisors Applications

• Microprocessor watchdog monitoring and reset circuits
• Memory battery backup switching systems
• System power-on reset generation
• Power failure detection logic

Supervisors Procurement Notes

Verify the specific suffix codes against the official datasheet to confirm the exact threshold voltage, reset timeout period, and package variant. Ensure compatibility with the target system's voltage levels and thermal requirements before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a dedicated voltage supervisor with integrated watchdog functionality is required. The fixed 3.0 V threshold suits applications monitoring standard logic or memory rails. Consider the open-drain output requirement for pull-up resistor implementation in the design phase.

Supervisors Part Context

This part belongs to the XC6124 series of voltage detectors with watchdog functions. The series utilizes CMOS process technology to achieve high precision and low power consumption. The XC6124 variants are distinguished primarily by their internal laser-trimmed detection thresholds and specific reset delay characteristics.

Supervisors Replacement Considerations

Cross-reference with other XC6124 series parts such as XC6124C628MR-G or XC6124C636MR-G if different threshold voltages are needed. Verify pinout compatibility with SOT-25-5 packages before substituting.
