XC6122A236ER-G

Supervisors Overview

The XC6122A236ER-G is a high-precision voltage detector with a watchdog function manufactured by Torex Semiconductor. It utilizes CMOS process technology and features an internal reference voltage source, delay circuit, comparator, and output driver. The detect voltage is fixed at 2.3V with a tolerance of ±2%. The operating voltage range spans from 1.0V to 6.0V. The device incorporates a watchdog timer with a timeout period of 100ms and a release delay time of 50ms. It employs an N-channel open-drain output configuration that goes low when the detected voltage falls below the threshold.

Supervisors Feature Summary

• Integrated watchdog function with built-in delay circuits eliminating external components
• EN/ENB pin allows independent control of the watchdog function while maintaining voltage detection
• High-precision laser-trimmed detect voltage with low temperature characteristics
• Low current consumption suitable for battery-powered applications

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 ER-G corresponds to the USP-6 package and tape-and-reel packaging format. Confirm the detect voltage code A236 aligns with the required 2.3V threshold. Ensure compatibility with the target system's voltage levels and interface requirements before finalizing procurement specifications.

Supervisors Selection Notes

Select this component when a fixed 2.3V detection threshold is required alongside integrated watchdog timing. The EN/ENB pin provides flexibility to disable the watchdog if only voltage monitoring is needed. Verify that the N-channel open-drain output matches the pull-up requirements of the connected microprocessor or logic circuit.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series of voltage detectors. The XC6122 variant specifically includes the watchdog function and ON/OFF control capabilities. These devices are designed for high-precision power management in compact surface-mount packages, offering a balance of accuracy and low power consumption for portable electronics.

Supervisors Replacement Considerations

XC6121A236ER-G: Lacks the watchdog function but shares the same detect voltage and package. XC6122A237ER-G: Shares the same package and watchdog features but has a different detect voltage of 2.4V.
