XC6123D541ER-G

Supervisors Overview

The XC6123D541ER-G is a high-precision voltage detector with an integrated watchdog timer manufactured by Torex Semiconductor. It utilizes CMOS process technology to provide power supply monitoring and system reset functions. The device features a fixed detection threshold of 4.1V, an active-low open-drain output, and a typical reset timeout of 100 ms. It operates within a supply voltage range of 1.6V to 5.0V and supports an operating temperature range of -40°C to +85°C. The component is housed in a compact 6-USP (1.8x2 mm) surface-mount package.

Supervisors Feature Summary

• Integrates a high-precision voltage detector with a built-in watchdog timer function using CMOS technology.
• Features an EN/ENB pin that allows independent control over the watchdog function while keeping the voltage detector operational.
• Provides an active-low open-drain or open-collector output signal upon voltage detection.
• Eliminates the need for external components for delay circuits due to internal integration.

Supervisors Applications

• Microprocessor reset circuits requiring system stability monitoring
• Memory battery backup circuits ensuring data integrity during power transitions
• General electronic systems needing reliable power supervision

Supervisors Procurement Notes

Verify the specific suffix ER-G against official Torex documentation to confirm the exact threshold voltage and packaging configuration. Ensure compatibility with the target application's voltage range and thermal requirements. Cross-reference the part number with authorized distributors to confirm current availability and authenticity. Check for any recent revisions to the datasheet that may affect electrical characteristics or pin assignments.

Supervisors Selection Notes

Select this component when a combined voltage supervisor and watchdog timer is required in a minimal footprint. The 4.1V threshold suits applications monitoring standard logic or power rails. Consider the 100ms typical timeout for system recovery needs. Verify that the open-drain output interface matches the microcontroller or logic input requirements of the design.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series of voltage detectors with watchdog functions. The series shares common architectural features including laser-trimmed detection voltages and low current consumption. Variations within the series typically differ by detection threshold voltage, watchdog timeout period, and output driver type, allowing customization for specific system constraints.

Supervisors Replacement Considerations

Consult official Torex documentation for confirmed substitute part numbers within the XC612x series. Ensure any replacement maintains the same detection threshold, output polarity, and package dimensions. Verify that alternative parts support the required operating temperature range and watchdog functionality without requiring external component changes.
