XC6122A742ER-G

Supervisors Overview

The XC6122A742ER-G is a high-precision voltage detector with an integrated watchdog timer manufactured by Torex Semiconductor. It operates within a supply voltage range of 1.0V to 6.0V and features a fixed detection threshold of 4.2V, set in 0.1V increments via laser trimming. The device provides a typical reset timeout period of 800ms and includes a built-in release delay circuit. It utilizes an N-channel open-drain output configuration that goes low upon detection. The component supports independent control of the watchdog function via the EN/ENB pin and functions reliably across an operating temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer with a built-in delay circuit for system monitoring without external components
• Features an internally pulled-up EN/ENB pin allowing the watchdog function to be disabled while voltage detection remains active
• Utilizes laser trimming technology to ensure high-precision detection voltage stability
• Provides an N-channel open-drain output signal that activates when the monitored voltage falls below the threshold

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 ER-G against the official Torex datasheet to confirm the package type and tape & reel specifications. Ensure the detection voltage code matches the required 4.2V threshold for your application design. Cross-reference the manufacturer part number with authorized distributors to confirm current availability and authenticity before procurement.

Supervisors Selection Notes

Select this component when a precise 4.2V threshold is required for voltage supervision combined with an 800ms watchdog timeout. The internal pull-up on the enable pin simplifies board layout by allowing the control pin to remain unconnected if the watchdog function is always active. Consider the 6-USP package dimensions for space-constrained surface-mount designs.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series of CMOS voltage detectors. The 'XC6122' designation indicates the inclusion of a watchdog timer function, distinguishing it from basic voltage monitors. The series is designed for industrial applications requiring low current consumption and high accuracy in power management scenarios.

Supervisors Replacement Considerations

Check the XC6122A741ER-G or XC6122A743ER-G for alternative thresholds within the same series. Verify compatibility with XC6124 variants if different enable pin configurations are needed.
