MCP112T-450E/MB

Supervisors Overview

The MCP112T-450E/MB is a micropower voltage detector manufactured by Microchip Technology. It operates within an ambient temperature range of -40°C to +125°C and utilizes a SOT-89-3 surface-mount package. The device features a fixed detection threshold voltage of 4.38V, ensuring precise monitoring of power supply rails. It provides a single channel of supervision with a push-pull active-low output configuration.

Supervisors Feature Summary

• Micropower consumption suitable for battery-operated applications
• Push-pull output stage providing robust drive capability
• Active-low signal assertion upon undervoltage event
• Fixed threshold voltage for reliable system reset generation

Supervisors Applications

• Portable consumer electronics requiring low standby current
• Battery-powered systems needing precise voltage supervision
• Embedded controllers requiring dedicated reset signals
• Industrial equipment operating in extended temperature ranges

Supervisors Procurement Notes

Verify the specific suffix MB corresponds to the SOT-89-3 package when sourcing. Confirm the E suffix indicates RoHS compliance and lead-free manufacturing status. Ensure the 450 designation matches the required 4.38V threshold for your specific circuit design requirements.

Supervisors Selection Notes

Select this component when a fixed 4.38V threshold is required with a push-pull output interface. The SOT-89-3 package offers a compact footprint for space-constrained designs. Consider the -40°C to +125°C operating range for industrial or automotive environments where standard commercial grades are insufficient.

Supervisors Part Context

This part belongs to the MCP112 series of CMOS voltage detectors from Microchip Technology. The series includes variants with different thresholds and output configurations. The MCP112T-450E/MB specifically denotes the 4.38V threshold variant in the SOT-89-3 package.

Supervisors Replacement Considerations

Direct substitutes include other MCP112 series parts with identical threshold voltages and output types but different packages, such as MCP112T-450E/TTG. Verify pinout compatibility before substitution.
