XC6122A522MR-G

Supervisors Overview

The XC6122A522MR-G is a high-precision voltage detector with watchdog function and ON/OFF control manufactured by Torex Semiconductor. It operates within an input voltage range of 1.0 V to 6.0 V and features a fixed detect voltage threshold of 2.2 V. The device utilizes CMOS process technology, consuming a typical operating current of 12 uA and a static current of 5 uA. It provides a watchdog timeout period of 200 ms and a reset delay time of 3.13 ms. The output configuration is N-channel open drain, active low. The component is housed in a SOT-25-5 surface-mount package and supports an operating temperature range from -40 C to +85 C.

Supervisors Feature Summary

• Integrates a watchdog timer function with built-in delay circuitry for system monitoring without external components
• Features an EN/ENB pin that allows independent control over the watchdog function while maintaining voltage detection
• Provides high-precision voltage detection using laser trimming technology with internal hysteresis

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 suffix 'MR-G' against the manufacturer's official datasheet to confirm the package type and tape/reel specifications. Ensure the detect voltage code corresponds to the required 2.2 V threshold for the design. Confirm RoHS compliance status through the official product documentation before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a single-channel voltage monitor with integrated watchdog functionality is required. The 2.2 V threshold suits applications where the supply rail drops below this level indicates a fault. The low current consumption makes it suitable for battery-powered systems. Verify that the SOT-25 package fits the PCB layout constraints.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series of voltage detectors. The series offers various detect voltages from 1.6 V to 5.0 V in 0.1 V increments. Different suffixes indicate variations in package style and watchdog timeout periods. The XC6122 variant specifically includes the watchdog feature controlled by the EN/ENB pin.

Supervisors Replacement Considerations

Other parts in the XC6122 series with different detect voltages or timeout periods may serve as functional substitutes if electrical parameters align. Verify package compatibility and pinout correspondence before substitution.
