XC6124D629MR-G

Supervisors Overview

The XC6124D629MR-G is a high-precision voltage detector with watchdog functionality from Torex Semiconductor. It operates within a supply voltage range of 1 V to 6 V and features a fixed detection threshold of 2.9 V. The device consumes 12 µA of operating current and 5 µA in standby mode. It provides an active-low open-drain reset output with a typical reset timeout of 1.6 s. The component supports power failure detection and includes an enable pin for watchdog control. It functions reliably across an industrial temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer with selectable timeout periods ranging from 50 ms to 1.6 s
• Features an EN/ENB pin that allows the watchdog function to be disabled while maintaining voltage monitoring
• Utilizes laser trimming technology to ensure high precision in internal voltage thresholds
• Provides built-in release delay circuits to prevent false resets without external components

Supervisors Applications

• Memory failure detection systems
• Microprocessor reset circuits
• Battery backup switching applications
• Power supply supervision in embedded devices

Supervisors Procurement Notes

Verify the specific suffix MR-G against the manufacturer's latest datasheet to confirm package type and tape/reel specifications. Ensure the required threshold voltage matches the fixed 2.9 V setting, as this parameter is internally determined by the part number code. Confirm RoHS compliance status directly with the supplier documentation prior to finalizing procurement orders.

Supervisors Selection Notes

Select this component when a single-channel voltage monitor with integrated watchdog timing is required. The fixed 2.9 V threshold suits applications monitoring 3.3 V or similar logic rails. Consider the low quiescent current for battery-operated designs. Verify that the open-drain output configuration aligns with the system's pull-up requirements and logic levels.

Supervisors Part Context

This part belongs to the XC6124 series of voltage detectors manufactured by Torex Semiconductor. The series utilizes CMOS process technology to achieve high precision and low current consumption. These devices are designed for supervisory applications requiring reliable reset generation and watchdog protection in compact surface-mount packages.

Supervisors Replacement Considerations

Cross-reference other XC6124 variants with different threshold codes if the 2.9 V detection level is unsuitable. Verify compatibility with alternative supervisor ICs offering similar watchdog features and SOT-25-5 packaging.
