XC6122A232MG-G

Supervisors Overview

The XC6122A232MG-G is a high-precision voltage detector with a watchdog function from the Torex XC6122 series. It features an N-channel open-drain output and operates within a supply voltage range of 1.0V to 6.0V. The device detects voltages between 1.6V and 5.0V in 0.1V increments, with a typical threshold of 3.2V for this specific model. It includes a built-in delay circuit for release delay times ranging from 3.13ms to 400ms and offers six selectable watchdog timeout periods from 50ms to 1.6s. The EN/ENB pin allows independent control of the watchdog function. It is housed in a SOT-25-5 package and supports operation from -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer with selectable timeout periods for microprocessor monitoring
• Features an internal delay circuit that eliminates the need for external components for release delay
• Includes an EN/ENB pin to independently disable the watchdog function while maintaining voltage detection
• Utilizes laser trimming technology for fixed detect voltage settings in 0.1V increments

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 detect voltage code (232 indicating 3.2V) and package suffix (MG-G for SOT-25) against the manufacturer datasheet. Confirm the watchdog timeout setting corresponds to the required application timing. Ensure compatibility with the system's operating voltage range and temperature specifications before integration.

Supervisors Selection Notes

Select this component when a single-channel voltage monitor with integrated watchdog functionality is required. The open-drain output requires an external pull-up resistor. Consider the available watchdog timeout options and release delay settings to match system recovery requirements. Verify that the 3.2V detection threshold aligns with the monitored rail voltage.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series of CMOS voltage detectors. The XC6122 variant specifically incorporates a watchdog function. The series is designed for low current consumption applications, utilizing laser trimming for precise voltage detection thresholds across a wide operating temperature range.

Supervisors Replacement Considerations

Cross-reference with other XC6122 series parts for different detect voltages or packages. Verify functional equivalence regarding watchdog timeout settings and release delay characteristics. Check for compatible pinouts if substituting with alternative packages like USP-6C.
