XC6122A342MR-G

Supervisors Overview

The XC6122A342MR-G is a high-precision voltage monitor manufactured by Torex Semiconductor, designed for power supply management applications. It operates within a supply voltage range of 1.0 V to 6.0 V and features a fixed detection threshold of 3.4 V. The device incorporates a CMOS output driver configured as an open-drain structure. Key functional parameters include a typical static current consumption of 5 µA and a working current of 12 µA. It provides a release delay time of 200 ms and includes a watchdog timer function with selectable timeout periods. The component is housed in a compact SOT-25-5 surface-mount package and supports operation across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer function controllable via the EN/ENB pin, allowing independent shutdown of the watchdog while maintaining voltage monitoring.
• Features a built-in delay circuit that generates release delay signals without requiring external components.
• Utilizes laser trimming technology to ensure high-precision detection voltages with low temperature characteristics.
• Provides N-channel open-drain output configuration for flexible interfacing with various logic families.

Supervisors Applications

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 operating temperature range and supply voltage requirements. Confirm RoHS compliance status through manufacturer documentation prior to integration into production designs.

Supervisors Selection Notes

Select this component when a precise 3.4 V threshold is required for single-input voltage monitoring. Consider the low quiescent current for battery-operated devices. Verify that the open-drain output capability meets the pull-up requirements of the connected system logic. Ensure the watchdog timeout settings align with the microcontroller's service interval.

Supervisors FAQ

How is the watchdog function controlled on the XC6122A342MR-G?

The watchdog function can be turned ON or OFF by setting the EN/ENB pin to a high or low level. The pin is internally pulled up to VIN or pulled down to VSS, allowing it to be left open if the watchdog is intended to remain active.

What is the output state when the detected voltage falls below the threshold?

When the input voltage drops below the detection threshold (VDFL), the output goes low. The output type is specified as CMOS open-drain.
