XC6124A731ER-G

Supervisors Overview

The XC6124A731ER-G is a high-precision voltage detector with watchdog function manufactured by Torex Semiconductor. It operates within an input voltage range of 1.6V to 5.0V and features a fixed detection threshold of 3.1V. The device utilizes CMOS technology for low current consumption and includes an internal delay circuit. It provides an N-channel open-drain output that goes low upon detection. The component supports watchdog timer functions with selectable timeout periods ranging from 50ms to 1.6s and release delay times from 3.13ms to 400ms. It is housed in a 6-USPC (1.8x2mm) package and operates between -40°C and +85°C.

Supervisors Feature Summary

• Integrates high-precision voltage detection with built-in watchdog timer functionality using CMOS process technology.
• Features an internally pulled-up EN/ENB pin, allowing the watchdog function to be disabled while maintaining voltage monitoring when left open.
• Provides flexible timing configurations with multiple selectable watchdog timeout periods and release delay times 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 official datasheet to confirm the 6-USPC package type and 3.1V threshold. Ensure compatibility with system voltage ranges between 1.6V and 5.0V. Confirm that the open-drain output configuration aligns with the target logic levels. Check for RoHS compliance status if required by assembly specifications.

Supervisors Selection Notes

Select this component when a combined voltage supervisor and watchdog timer is required in a compact surface-mount package. The internally pulled enable pin simplifies design by removing the need for external pull-up resistors for the watchdog control. Suitable for applications requiring precise voltage monitoring with minimal external component count and low standby current consumption.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series of voltage detectors. The XC6124 variant specifically integrates watchdog functionality. The 'A' suffix typically denotes the detection voltage code, corresponding to 3.1V in this context. The 'ER-G' indicates the specific package and environmental compliance.

Supervisors Replacement Considerations

Cross-reference with other XC6124 series parts for different thresholds or packages. Verify functional equivalence with XC6122 series if watchdog control pin polarity differs. Ensure substitute parts maintain the same 6-USPC footprint and electrical characteristics.
