XC6122A641MR-G

Supervisors Overview

The XC6122A641MR-G is a high-precision voltage detector with a watchdog timer manufactured by Torex Semiconductor Ltd. It operates within a supply voltage range of 1 V to 6 V and features a fixed detection threshold of 4.1 V. The device utilizes CMOS technology and provides an open-drain output that goes low upon detection. Key electrical parameters include a typical operating current of 12 uA, a static current of 5 uA, and a power dissipation rating of 250 mW. The reset delay time is specified at 200 ms, and the unit functions reliably across an extended temperature range from -40 °C to +85 °C.

Supervisors Feature Summary

• Integrates a watchdog timer function controllable via the EN/ENB pin while maintaining voltage detection operation
• Features an internal pull-up or pull-down on the control pin allowing flexible configuration without external components
• Provides a low-active open-drain output signal for system reset and monitoring applications

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 MR-G against the manufacturer's official datasheet to confirm package type and tolerance specifications. Ensure the required detection threshold matches the fixed 4.1 V value documented for this part number. Confirm RoHS compliance status through the latest environmental certification documents provided by Torex Semiconductor before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a fixed 4.1 V threshold is required for single-channel voltage monitoring. The integrated watchdog functionality eliminates the need for external timing components, reducing board space. Consider the 12 uA operating current for battery-powered designs requiring low quiescent consumption. Verify that the open-drain output interface aligns with the target microcontroller input requirements.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series of voltage detectors incorporating CMOS process technology. The series offers high precision and low current consumption with built-in delay circuits. These ICs combine reference voltage sources, comparators, and output drivers into a compact SOT-25-5 package suitable for surface mount assembly in portable electronic devices.

Supervisors Replacement Considerations

Cross-reference with other XC6122 series variants having different detection thresholds if the voltage level requires adjustment. Verify functional compatibility with XC6121 or XC6123 series parts regarding pinout and output characteristics before substitution.
