XC6122D432ER-G

Supervisors Overview

The XC6122D432ER-G is a high-precision voltage detector with a watchdog timer manufactured by Torex Semiconductor. It operates within a supply voltage range of 1 V to 6 V and features a fixed detect voltage of 3.2 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 delays ranging from 3.13 ms to 400 ms. The watchdog timeout period is selectable between 50 ms and 1.6 s. The component is housed in a compact 6-USPC (1.8x2 mm) package and functions reliably across an ambient temperature range of -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 within the timeout period.
• Features an EN/ENB pin that allows independent control over the watchdog function while keeping the voltage detector operational.
• Employs laser trimming technology to ensure high-precision internal detection voltages without requiring external components.

Supervisors Applications

• Microprocessor watchdog monitoring and reset circuits
• Memory battery backup circuits
• System power-on reset circuits

Supervisors Procurement Notes

Verify the exact detect voltage code suffix against the official datasheet to confirm the 3.2 V threshold. Ensure the selected package variant matches the required PCB footprint dimensions. Confirm RoHS compliance status through the manufacturer's latest documentation before finalizing procurement specifications.

Supervisors Selection Notes

Select this component when a low-current supervisory circuit with integrated watchdog timing is required. The fixed 3.2 V threshold suits applications monitoring standard logic or battery levels. Verify that the open-drain output configuration aligns with the system's pull-up requirements and logic interface standards.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series of voltage detectors. These devices are designed for high-precision monitoring using CMOS processes. The series offers various detect voltages and package options to accommodate different system constraints and space limitations.

Supervisors Replacement Considerations

Consult the official Torex cross-reference guide for verified substitutes. Ensure any replacement maintains the same detect voltage, package type, and watchdog functionality to guarantee system compatibility.
