XC6122C425ER-G

Supervisors Overview

The XC6122C425ER-G is a high-precision voltage monitor manufactured by Torex Semiconductor, designed for single-input power supervision. It operates within a supply voltage range of 1 V to 6 V and detects input voltages from 1.6 V to 5.0 V with 100 mV increments. The device features an N-channel open-drain CMOS output that asserts low upon detection. Key electrical parameters include a typical static current of 5 uA and a working current of 12 uA. It incorporates a watchdog timer and offers a reset delay time of 50 ms. The component is housed in a USP-6C package and supports operation across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog function controllable via the EN/ENB pin while maintaining voltage detection operation
• Utilizes laser trimming technology to ensure fixed detect voltage accuracy within the specified range
• Features built-in delay circuits that eliminate the need for external components for release delay signals
• Provides N-channel open-drain output configuration suitable for direct interfacing with digital logic

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 codes against the official datasheet to confirm the exact threshold voltage and package variant. Ensure compatibility with the target system's voltage levels and thermal requirements. Confirm RoHS compliance status through manufacturer documentation before integration into regulated environments.

Supervisors Selection Notes

Select this component when a low-power supervisory circuit with integrated watchdog functionality is required. The USP-6C package suits space-constrained surface-mount designs. Verify that the 50 ms reset delay aligns with the system's startup timing constraints and that the open-drain output matches the pull-up requirements of the connected microcontroller.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series of voltage detectors developed by Torex Semiconductor. The series utilizes CMOS process technology to achieve high precision and low current consumption. These devices are engineered for reliable power management in portable and industrial electronics where stable voltage supervision is critical.

Supervisors Replacement Considerations

Cross-reference with other XC6122 variants sharing the USP-6C package and similar electrical characteristics. Verify that substitute parts maintain identical threshold voltage tolerances and watchdog timeout configurations to ensure functional equivalence without circuit redesign.
