XC6122F732MR-G

Supervisors Overview

The XC6122F732MR-G is a high-precision voltage detector with a watchdog timer manufactured by Torex Semiconductor. It operates within a supply voltage range of 1.0 V to 6.0 V and monitors input voltages from 1.6 V to 5.0 V in 0.1 V increments. The device features a fixed detection threshold of 3.2 V with ±2% accuracy. It utilizes an N-channel open-drain output for active-low reset signals. Key electrical parameters include a typical static current of 5 μA and a working current of 12 μA. The component supports a watchdog timeout period of 800 ms and a release delay time of 100 ms, functioning reliably across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer function controllable via the EN/ENB pin to manage system stability independently of the voltage monitoring circuit.
• Employs CMOS technology to achieve low power consumption suitable for battery-operated applications while maintaining high detection precision.
• Features an internal delay circuit that eliminates the need for external components to generate release delay times after voltage recovery.
• Utilizes laser trimming technology to fix the detection voltage internally, ensuring consistent performance without external resistor adjustments.

Supervisors Applications

• Microprocessor watchdog monitoring and reset circuits
• Memory battery backup systems
• System power-on reset logic

Supervisors Procurement Notes

Verify the specific suffix codes against official datasheets to confirm the exact detection voltage and delay settings. Ensure compatibility with the target PCB footprint, typically SOT-25-5 or USP-6C. Confirm RoHS compliance status if required by regulatory standards. Cross-reference the manufacturer part number with distributor catalogs to avoid confusion with similar series variants.

Supervisors Selection Notes

Select this component when a fixed 3.2 V threshold is required for precise power rail monitoring. Consider the 800 ms watchdog timeout if the application demands longer intervals between reset pulses. Evaluate the 5 μA static current against total system budget constraints. Verify that the open-drain output interface matches the microcontroller's input requirements.

Supervisors Part Context

This device belongs to the XC6121/XC6122/XC6123/XC6124 series of voltage detectors. These components are designed for general-purpose power management tasks requiring reliable supervision of operating voltages. The series shares common architectural features such as low current consumption and integrated watchdog functionality, differing primarily in detection thresholds and package options.

Supervisors Replacement Considerations

Check for other XC6122 variants with different threshold voltages if the 3.2 V setting is not optimal. Verify pinout compatibility with alternative supervisor ICs before substitution. Ensure replacement parts support the same watchdog timeout configuration and output drive capabilities.
