XC6123C219MG-G

Supervisors Overview

The XC6123C219MG-G is a CMOS voltage monitor manufactured by Torex Semiconductor, designed for supervisory circuit applications. It operates within a supply voltage range of 1.0 V to 6.0 V and features a fixed detection threshold voltage of 1.9 V with a typical hysteresis width of 5% of the detection voltage. The device incorporates a watchdog timer function and provides an open-drain output type. It is housed in a compact SOT-25-5 surface-mount package and supports an operating temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer function controllable via the EN/ENB pin
• Features laser-trimmed detection voltage accuracy of ±2%
• Provides low current consumption suitable for battery-powered systems

Supervisors Applications

• Microprocessor reset circuits
• Power failure detection systems
• Memory backup power switching

Supervisors Procurement Notes

Verify the specific suffix MG-G corresponds to the SOT-25-5 package configuration. Confirm the C-series designation aligns with the required 1.9 V threshold voltage for your design. Ensure compatibility with the specified operating temperature range and output drive requirements before finalizing procurement specifications.

Supervisors Selection Notes

Select this component when a precise 1.9 V monitoring level is required alongside integrated watchdog functionality. The open-drain output necessitates an external pull-up resistor. Consider the SOT-25-5 footprint constraints and verify that the 1.0 V minimum operating voltage meets the system's lowest supply rail conditions during brown-out scenarios.

Supervisors Part Context

This part belongs to the XC6123 series of high-precision voltage detectors with watchdog functions. The series utilizes CMOS technology to achieve low power consumption while maintaining high detection accuracy through laser trimming. The XC6123 variant specifically includes the watchdog timer feature, distinguishing it from basic voltage monitors in the broader product family.
