XC6122C547ER-G

Supervisors Overview

The XC6122C547ER-G is a high-precision voltage detector with a watchdog function manufactured by Torex Semiconductor. It operates within a supply voltage range of 1.0 V to 6.0 V and features a fixed detection threshold of 4.7 V. The device utilizes CMOS process technology, drawing a typical operating current of 12 µA and a static current of 5 µA. It provides an N-channel open-drain output that goes low upon detection. Integrated delay circuits eliminate the need for external components for release timing. The unit supports a watchdog timeout period of 400 ms and includes a reset delay time of 400 ms. It functions reliably across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer with selectable timeout periods for system monitoring
• Features built-in delay circuits for release timing without external components
• Includes EN/ENB pin for independent control of the watchdog function
• Utilizes laser trimming technology for high-precision voltage detection

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 codes against the official datasheet to confirm the exact detection voltage and reset delay time, as these parameters vary significantly across the XC6122 series. Ensure the ordering information matches the required package type and electrical specifications for the target application design.

Supervisors Selection Notes

Select this component when a fixed 4.7 V threshold is required for systems operating between 1.0 V and 6.0 V. Consider the integrated watchdog functionality if microprocessor stability monitoring is needed. Verify that the N-channel open-drain output configuration aligns with the downstream logic interface requirements.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series of voltage detectors from Torex Semiconductor. These devices are designed for applications requiring precise voltage supervision and system reset management. The series employs CMOS technology to achieve low power consumption while maintaining high accuracy through internal laser trimming.

Supervisors Replacement Considerations

Cross-reference other XC6122 variants with different suffixes to find alternatives with matching 4.7 V thresholds or compatible watchdog timings. Verify pinout compatibility and package dimensions before substituting.
