UM823MP

Supervisors Overview

The UM823MP is a power management supervisor IC from Union Semiconductor International Limited, designed to monitor multiple voltage rails in electronic systems. It features a single channel with open drain or open collector output configuration housed in a compact SOT-353 package. This component serves as a system reset circuit supervisor, monitoring power supply voltage to ensure reliable operation of digital systems by detecting under-voltage conditions and generating appropriate reset signals.

Supervisors Feature Summary

• Single-channel voltage monitoring capability for critical power rails
• Open drain or open collector output configuration for flexible interfacing
• Compact SOT-353 surface-mount package design
• System reset supervision functionality for digital applications

Supervisors Applications

• Digital system power supply monitoring
• Voltage rail supervision in embedded systems
• Reset circuit generation for microcontroller systems

Supervisors Procurement Notes

Verify the exact electrical specifications including threshold voltages and response times from the official Union Semiconductor datasheet. Confirm the output configuration (open drain vs open collector) matches your system requirements. Ensure the SOT-353 package footprint aligns with your PCB layout. Check temperature range specifications for your operating environment.

Supervisors Selection Notes

Select this component when single-channel voltage monitoring with minimal pin count is required. The SOT-353 package offers space-efficient mounting for compact designs. Consider the open drain/open collector output flexibility for various logic level interfacing needs. Verify that the monitoring threshold meets your specific voltage rail requirements before implementation.
