XC6121C430ER-G

Supervisors Overview

The XC6121C430ER-G is a high-precision voltage detector with a watchdog function and ON/OFF control, manufactured by Torex Semiconductor Ltd using CMOS process technology. It features an internally fixed detect voltage of 4.3V, monitored via a single channel. The device operates within a supply voltage range of 1.6V to 5.0V and provides an active-low N-channel open-drain output. Key internal components include a reference voltage source, delay circuit, comparator, and output driver. The watchdog timeout period is typically 100ms, while the release delay time is adjustable. The component is housed in a compact 6-USPC (1.8x2mm) surface-mount package.

Supervisors Feature Summary

• Integrated watchdog timer function with configurable timeout periods for system monitoring
• Built-in delay circuit eliminates the need for external timing components
• Dedicated EN/ENB pin allows independent control over the watchdog function state
• High-precision detection voltage established via laser trimming technology

Supervisors Applications

• Microprocessor watchdog monitoring and reset circuits
• Memory battery backup circuits
• System power-on reset circuits
• Power failure detection systems

Supervisors Procurement Notes

Verify the specific suffix 'ER-G' against the manufacturer's official datasheet to confirm the exact package type and tape-and-reel specifications. Ensure the detect voltage code matches the required 4.3V threshold for the target application. Cross-reference RoHS compliance status with current regulatory requirements before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a fixed 4.3V threshold is required for voltage supervision. The integrated watchdog feature simplifies design by removing external timing parts. Consider the 6-USPC package dimensions for PCB layout constraints. Verify that the operating temperature range meets the environmental conditions of the intended deployment scenario.

Supervisors Part Context

This part belongs to the XC6121 series, which groups high-precision, low-current voltage detectors. The series utilizes CMOS technology to provide reliable monitoring with minimal power consumption. The XC6121 variant specifically includes the watchdog functionality, distinguishing it from basic supervisor ICs in the broader product family.

Supervisors Replacement Considerations

Consult the official datasheet for confirmed substitute part numbers within the XC6121 series. Verify compatibility of detect voltage and package footprint before substituting.
