XC6123D431ER-G

Supervisors Overview

The XC6123D431ER-G is a high-precision voltage detector with an integrated watchdog timer manufactured by Torex Semiconductor. It utilizes CMOS process technology and laser trimming for accurate detection thresholds. The device monitors a single voltage input with a threshold of 4.1V. It features an active-low reset output with open-drain or open-collector configuration. The typical reset timeout period is 100 ms. The IC operates within a supply voltage range of 1.6V to 5.0V and supports an operating temperature range from -40°C to +85°C. It is housed in a compact 6-USP (1.8x2) surface-mount package.

Supervisors Feature Summary

• Integrates a watchdog timer function with the voltage detector for system monitoring
• Utilizes laser trimming technology to ensure high-precision detect voltage accuracy
• Features an enable pin to control the on/off state of the watchdog function independently
• Provides low current consumption suitable for battery-powered applications

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 official Torex datasheet to confirm the package type and tape & reel packaging details. Ensure the order quantity aligns with standard manufacturing reels. Cross-reference the part number with the manufacturer's latest documentation to confirm availability status and any potential obsolescence notices before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a combined voltage supervision and watchdog timer is required in a minimal footprint. The fixed 4.1V threshold suits applications where this specific voltage level requires monitoring. Consider the 6-USP package constraints for PCB layout. Verify that the open-drain output compatibility matches the downstream logic interface requirements of the target microcontroller or processor.

Supervisors Part Context

This part belongs to the XC6121/2/3/4 series of voltage detectors from Torex Semiconductor. These devices are designed for general-purpose power management, offering high precision and low power consumption. The series differentiates models primarily through detect voltage thresholds and specific feature combinations like the inclusion of watchdog timers or manual reset capabilities.

Supervisors Replacement Considerations

Direct substitutes include other XC6123 series variants with different detect voltages if the threshold can be adjusted externally or if the application allows.
