XC6123E441ER-G

Supervisors Overview

The XC6123E441ER-G is a high-precision voltage detector with an integrated watchdog timer manufactured by Torex Semiconductor. It operates within a supply voltage range of 1.0V to 6.0V and features a fixed detection threshold of 4.1V. The device utilizes CMOS technology, drawing a typical operating current of 12µA and a standby current of 5µA. It provides an open-drain output that goes low upon power failure detection. The watchdog function offers a reset timeout of 200ms. The component is housed in a 6-USP (1.8x2) surface-mount package and supports an industrial operating temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrates a high-precision voltage monitor with a built-in watchdog timer for comprehensive system supervision.
• Features an EN/ENB control pin that allows independent disabling of the watchdog function while maintaining voltage monitoring.
• Utilizes an open-drain output structure requiring no external components for delay or signal generation.
• Employs laser-trimmed internal reference voltages to ensure accurate detection thresholds without external calibration.

Supervisors Applications

• Microprocessor watchdog monitoring and reset circuitry
• Memory battery backup circuit supervision
• System power-on reset logic implementation
• Power failure detection in portable electronic devices

Supervisors Procurement Notes

Verify the specific suffix ER-G corresponds to the USP-6C package and 4.1V threshold when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design compatibility with the open-drain output configuration and required pull-up resistor values for the target logic levels.

Supervisors Selection Notes

Select this component when a combined voltage supervisor and watchdog timer is required in a compact surface-mount footprint. The 4.1V threshold suits applications monitoring standard 3.3V or 5V rails with appropriate margin. Consider the 200ms watchdog timeout relative to the microcontroller's maximum interrupt response time to ensure reliable fault recovery.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series of voltage detectors. The XC6123 designation specifically indicates the inclusion of a watchdog timer function alongside the primary voltage monitoring capabilities. The series is designed for low-power applications utilizing advanced CMOS process technology to minimize quiescent current consumption.

Supervisors Replacement Considerations

Cross-reference XC6123E441MR-G for SOT-25 packaging alternatives. Verify functional equivalence regarding the 4.1V threshold and 200ms timeout before substitution. Package dimensions and pinout configurations differ between USP-6C and SOT-25 formats.
