XC6124C436MR-G

Supervisors Overview

The XC6124C436MR-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 features a fixed detection threshold of 3.6 V. The device utilizes CMOS technology, consuming a typical operating current of 12 µA and a static current of 5 µA. It provides an active-low open-drain output with a standard reset delay time of 50 ms. The watchdog function supports multiple timeout periods, and the EN/ENB pin allows independent control of the watchdog while maintaining voltage monitoring. It is housed in a compact SOT-25-5 package.

Supervisors Feature Summary

• Integrates a high-accuracy voltage detector with a built-in watchdog timer for system reliability.
• Features an EN/ENB control pin that enables independent shutdown of the watchdog function without affecting voltage monitoring.
• Utilizes laser trimming technology to ensure precise detection voltage thresholds across temperature variations.
• Provides an active-low open-drain output compatible with various logic families.

Supervisors Applications

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

Supervisors Procurement Notes

Verify the specific suffix 'C' indicates the correct detection voltage code (3.6V) and 'MR' denotes the SOT-25-5 package configuration. Confirm RoHS compliance status and check for any manufacturer-specific ordering restrictions or minimum reel quantities before finalizing procurement documentation.

Supervisors Selection Notes

Select this component when a single-channel voltage supervisor with watchdog functionality is required. Ensure the 3.6V threshold aligns with the monitored rail. Consider the 50ms default reset delay and available watchdog timeout options. Verify that the open-drain output interface matches the target microcontroller's input requirements.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series of voltage detectors. These devices are designed for low-power applications requiring precise supervision. The XC6124 variant specifically includes the watchdog timer feature, distinguishing it from basic voltage monitors in the same family.

Supervisors FAQ

How is the watchdog function controlled?

The watchdog function can be turned ON or OFF independently via the EN/ENB pin. Setting this pin to a low or high level disables the watchdog while the voltage detector continues to operate.

What is the output configuration?

The device features an N-channel open-drain output. The output goes low when a detected voltage condition is met or a watchdog timeout occurs.
