XC6124A216ER-G

Supervisors Overview

The XC6124A216ER-G is a high-precision voltage detector with watchdog function manufactured by Torex Semiconductor. It operates within a supply voltage range of 1V to 6V and features a fixed detect voltage threshold of 1.6V, determined via laser trimming technology. The device incorporates an N-channel open-drain output driver and includes a built-in delay circuit for release timing. It supports configurable watchdog timeout periods ranging from 50ms to 1.6s and offers five selectable release delay time settings between 3.13ms and 400ms. The IC consumes low current and functions reliably across an industrial temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a high-precision voltage detector with a comparator and CMOS output driver for system supervision.
• Includes a built-in watchdog timer with configurable timeout periods to monitor microprocessor activity.
• Features an EN/ENB pin that allows independent control over the watchdog function while maintaining voltage detection.
• Utilizes laser trimming technology to ensure accurate internal fixed detect voltages without external components.

Supervisors Applications

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

Supervisors Procurement Notes

Verify the specific suffix ER-G against the manufacturer's official datasheet to confirm the package type and electrical characteristics match project requirements. Ensure compatibility with the required detect voltage threshold and watchdog timeout settings before finalizing procurement. Cross-reference the part number with authorized distributors to confirm availability and authenticity.

Supervisors Selection Notes

Select this component when a single-channel voltage supervisor with integrated watchdog functionality is required. It is suitable for applications needing precise voltage monitoring with low current consumption. Consider the available release delay times and watchdog timeout options to match system timing constraints. Verify that the operating voltage range covers the application's supply rails.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series of voltage detectors. These ICs are designed for high-precision monitoring in portable and industrial electronics. The series utilizes CMOS process technology to achieve low power consumption while maintaining accuracy through laser-trimmed reference voltages.

Supervisors Replacement Considerations

Check for other XC6124 variants with different detect voltages or packages if the 1.6V threshold does not match the target rail. Verify functional equivalence with other supervisors offering similar watchdog and delay features.

Supervisors FAQ

How is the watchdog function controlled?

The watchdog function can be turned on or off by setting the EN/ENB pin to a low or high level, allowing the voltage detector to remain operational independently.

What is the typical hysteresis width?

The typical hysteresis width is +100ppm/°C regarding temperature characteristics, ensuring stable detection thresholds across varying conditions.
