MCP102-300E/TO

Supervisors Overview

The MCP102-300E/TO is a micropower voltage supervisor from Microchip Technology, designed to monitor a single power supply rail. It features an active low push-pull output and operates within a supply voltage range of 1 V to 5.5 V. The device triggers a reset when the monitored voltage drops below a threshold of approximately 2.886 V or exceeds an overvoltage limit of 2.974 V. It includes a fixed reset delay time of 120 ms and consumes only 1 µA of quiescent current. Qualified under AEC-Q100 standards for automotive applications, it functions reliably across an extended temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Provides hardware-based system reset via active low push-pull output
• Monitors both undervoltage and overvoltage conditions on a single input
• Operates with ultra-low quiescent current consumption
• Automotive qualified for high reliability environments

Supervisors Applications

• Microcontroller power supply monitoring in automotive systems
• Battery-powered devices requiring low standby current
• Industrial control units needing extended temperature operation
• Embedded systems with strict reset timing requirements

Supervisors Procurement Notes

Verify the specific suffix TO indicates the TO-92-3 package configuration. Confirm AEC-Q100 qualification status matches project requirements. Ensure operating voltage ranges align with the target power rail. Check datasheet for exact threshold tolerances at different temperatures. Validate pinout compatibility with existing PCB footprints before integration.

Supervisors Selection Notes

Select this component when a single-channel supervisor with push-pull output is required. Consider the 120 ms reset delay for system startup timing. Evaluate the 1 µA current draw against battery life constraints. Verify that the 1 V to 5.5 V input range covers the application's voltage spectrum. Assess thermal performance within the -40°C to +125C operational window.

Supervisors Part Context

This part belongs to the MCP102 series of micropower voltage supervisors. It shares functional similarities with other members like MCP102T-300E/LB but differs in packaging and form factor. The series is designed for cost-sensitive applications requiring reliable power management without complex configuration options.

Supervisors Replacement Considerations

MCP102T-300E/LB offers identical electrical specifications but uses SC-70-3 surface mount packaging instead of through-hole TO-92-3.
