XC6122C650ER-G

Supervisors Overview

The XC6122C650ER-G is a high-precision voltage monitor with an integrated watchdog timer manufactured by Torex Semiconductor. It operates within a supply voltage range of 1 V to 6 V and features a fixed detection threshold of 5.0 V, determined by laser trimming technology. The device utilizes CMOS process technology and provides an N-channel open-drain output that goes low upon detection. Key electrical parameters include a maximum operating current of 12 µA and a typical static current of 5 µA. It supports a reset delay time of 50 ms and functions reliably across an industrial temperature range from -40 °C to +85 °C.

Supervisors Feature Summary

• Integrates a watchdog timer function with internal pull-up control on the EN/ENB pin for simplified circuit design
• Provides high-precision voltage detection using laser-trimmed reference voltages without external components
• Features low current consumption suitable for battery-powered applications
• Includes built-in release delay circuits to prevent false triggering during power transitions

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 package type USP-6C and lead times. Ensure the detection voltage matches the required system threshold of 5.0 V. Confirm RoHS compliance status directly with the manufacturer or authorized distributors before finalizing procurement specifications.

Supervisors Selection Notes

Select this component when a fixed 5.0 V threshold is required for supervisory applications. The XC6122 series is appropriate for designs needing integrated watchdog functionality without external timing components. Consider the 12 µA operating current for power-sensitive designs. Verify that the open-drain output configuration aligns with the target logic levels of the monitored microprocessor or system.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series of voltage detectors. These ICs are designed for high-precision monitoring in portable and industrial electronics. The series differentiates primarily by detection voltage ranges and specific feature sets like manual reset availability. The XC6122 variant specifically includes the watchdog timer function controlled via the EN/ENB pin.

Supervisors Replacement Considerations

Cross-reference other XC6122 series variants with different detection voltages if the 5.0 V threshold does not match the application requirements. Verify compatibility with alternative packages such as USP-6C or SOT-26-3 if footprint changes are permissible. Ensure substitute parts maintain the same watchdog timeout and release delay characteristics.
