XC6122F641ER-G

Supervisors Overview

The XC6122F641ER-G is a high-precision voltage detector with an integrated watchdog timer manufactured by Torex Semiconductor. It operates within a supply voltage range of 1V to 6V and features a fixed detection threshold of 4.1V. The device utilizes CMOS process technology for low current consumption, with a typical operating current of 12µA and standby current of 5µA. It provides a reset timeout period of 800ms and includes a release delay time of 3.13ms. The output driver is configured as an open drain or open collector type, active low. The component is housed in a compact 6-USP (1.8x2) surface-mount package and supports an operating temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer function that outputs a reset signal if the input maintains a specific logic level for a defined timeout period.
• Features an EN/ENB pin that allows independent control over the watchdog function while keeping the voltage detector operational.
• Utilizes laser trimming technology to ensure high precision in the internally fixed detect voltage settings.
• Provides built-in delay circuits for release delay times without requiring external components.

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 'F' against the official Torex datasheet to confirm the exact watchdog timeout period and release delay characteristics, as these parameters vary across the XC6122 series. Ensure the required detection voltage matches the internal fixed value associated with this part number variant. Confirm compatibility with the 6-USP package dimensions for PCB layout integration.

Supervisors Selection Notes

Select this component when a combined voltage supervision and system integrity check via watchdog timer is required. The open-drain output facilitates interfacing with various logic levels. Consider the 12µA operating current for battery-powered applications where energy efficiency is critical. Verify that the 4.1V threshold aligns with the monitored rail voltage requirements.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series of voltage detectors with watchdog functions. The XC6122 designation specifically indicates the inclusion of an enable/disable pin for the watchdog feature. The series is designed for applications requiring reliable power management and system reset capabilities in compact form factors.

Supervisors Replacement Considerations

Other variants within the XC6122 series may serve as functional substitutes if the detection voltage and timing parameters match the application requirements. Cross-reference the specific timeout and delay codes to ensure electrical equivalence.
