XC6122A534ER-G

Supervisors Overview

The XC6122A534ER-G is a high-precision voltage detector with a watchdog function manufactured by Torex Semiconductor. It operates within a supply voltage range of 1 V to 6 V and features a fixed detection threshold of 3.4 V. The device utilizes CMOS technology, drawing a typical operating current of 12 µA and a standby current of 5 µA. It provides an N-channel open-drain output and includes a built-in delay circuit for release timing. The component is housed in a compact 6-pin USP package (6-USPC) suitable for surface mount applications.

Supervisors Feature Summary

• Integrates a watchdog timer function that triggers a reset if the input signal remains static within the timeout period.
• Features an EN/ENB pin that allows independent control over the watchdog function while maintaining voltage monitoring operation.
• Utilizes laser trimming technology to ensure high precision in internally fixed detect voltages across the series range.

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 against the official Torex datasheet to confirm the package type and tape-and-reel configuration. Ensure the required detection voltage corresponds to the '534' code (3.4V) for your design. Confirm RoHS compliance status through the manufacturer's latest documentation before finalizing procurement specifications.

Supervisors Selection Notes

Select this component when a fixed 3.4 V threshold is required for system supervision. The integrated watchdog feature simplifies design by eliminating external timing components. Consider the low quiescent current for battery-powered applications. Verify that the 6-USPC package dimensions fit the available PCB footprint constraints.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series of voltage detectors. These ICs are designed for high-precision monitoring using CMOS processes. The series offers various fixed detection voltages and watchdog timeout options, providing flexibility for different system requirements while maintaining a consistent interface and package form factor.

Supervisors Replacement Considerations

Cross-reference with other XC6122 variants having different detection voltages or watchdog settings. Verify compatibility with alternative supervisor ICs offering similar 3.4 V thresholds and open-drain outputs, ensuring pinout and electrical characteristics match the original design requirements.
