XC6122E429ER-G

Supervisors Overview

The XC6122E429ER-G is a high-precision voltage detector with watchdog function and ON/OFF control from Torex Semiconductor. It operates within a supply voltage range of 1 V to 6 V, featuring a fixed detect threshold voltage of 2.9 V. The device incorporates an N-channel open-drain output configuration and includes a built-in delay circuit for release timing. It supports multiple watchdog timeout periods ranging from 50 ms to 1.6 s and offers five selectable release delay time settings between 3.13 ms and 400 ms. The IC utilizes laser trimming technology for accurate voltage detection and maintains low current consumption suitable for battery-powered applications.

Supervisors Feature Summary

• Integrates a watchdog timer function that outputs a reset signal if the input signal remains constant within the specified timeout period.
• Features an EN/ENB pin that allows independent control over the watchdog function while keeping the voltage detector operational.
• Utilizes CMOS process technology to achieve high precision and low current consumption without requiring external components for delay circuits.

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 manufacturer's official datasheet to confirm package type and electrical characteristics. Ensure compatibility with system voltage requirements and temperature ranges before integration. Cross-reference part numbers with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status as per the latest product documentation.

Supervisors Selection Notes

Select this component when a single-input voltage monitor with integrated watchdog functionality is required. The fixed 2.9 V threshold suits applications monitoring 3.3 V or similar logic levels. Consider the available watchdog timeout options and release delay settings to match system timing constraints. Verify that the open-drain output interface aligns with the connected microcontroller or logic gate inputs.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series of voltage detectors. These devices are designed for high-precision monitoring in portable electronics and industrial systems. The series shares common architectural features including laser-trimmed thresholds and internal pull-up/down mechanisms on control pins, ensuring reliable operation across varying environmental conditions.

Supervisors Replacement Considerations

Compatible substitutes within the same series include XC6122E429MR-G (different package) or other XC6122 variants with matching 2.9 V thresholds. Verify pinout compatibility and electrical specifications before substitution. No direct cross-brand replacements are confirmed in public documentation.
