XC6124C538ER-G

Supervisors Overview

The XC6124C538ER-G is a high-precision voltage detector manufactured by Torex Semiconductor. It features a fixed detection threshold of 3.8V and operates within a supply voltage range of 1.0V to 6.0V. The device incorporates a built-in watchdog timer with a standard timeout period of 400ms and utilizes an N-channel open-drain output configuration for low-active reset signaling. Designed for robust performance, it maintains a typical hysteresis width of 5% relative to the detection voltage and exhibits a temperature coefficient of +100ppm/°C. The component is housed in a compact 6-USPC (1.8x2) surface-mount package and supports an operating temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog function controllable via the EN/ENB pin while maintaining voltage detection operation
• Utilizes laser trimming technology to ensure high-precision fixed detection voltages without external components
• Features a built-in delay circuit that eliminates the need for external release delay timing components

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 ER-G against the official Torex datasheet to confirm the 6-USPC package type and standard 400ms watchdog timeout. Ensure the 3.8V detection threshold aligns with the target system voltage requirements. Confirm RoHS compliance status and lead time availability through authorized distributors prior to finalizing procurement plans.

Supervisors Selection Notes

Select this component when a fixed 3.8V threshold with integrated watchdog functionality is required. The open-drain output necessitates an external pull-up resistor for proper logic level interfacing. Consider the 400ms watchdog timeout duration to ensure compatibility with the microcontroller's clock cycle and interrupt response times within the application design.

Supervisors Part Context

This part belongs to the XC6124 series of voltage detectors with watchdog functions. The series employs CMOS process technology to achieve low current consumption, with a typical static current of 5µA. The XC6124 variant specifically provides an N-channel open-drain output and includes an enable pin for independent control of the watchdog feature, distinguishing it from basic voltage monitors.

Supervisors Replacement Considerations

XC6124C538MR-G: Offers identical electrical specifications but utilizes an SOT-25-5 package instead of 6-USPC.
