MIC2774L-29BM5-TR

Supervisors Overview

The MIC2774L-29BM5-TR is a dual voltage supervisor from Microchip Technology, housed in a 5-pin SOT-23 package. It monitors two input voltages with fixed thresholds of 0.3V and 2.93V. The device features an active-low push-pull output and includes a manual reset input. It operates within a supply voltage range of 1.5V to 5.5V and has a reset delay time of 280 ms. The component functions across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Dual-channel monitoring capability for independent power rails
• Manual reset input for system control flexibility
• Active-low push-pull output structure

Supervisors Applications

• Embedded systems requiring dual power rail supervision
• Portable electronics with low-voltage battery monitoring
• Industrial control units needing under-voltage protection

Supervisors Procurement Notes

Verify the specific suffix 'BM5' against official Microchip documentation to confirm pinout and threshold specifications. Ensure compatibility with the target PCB footprint and operating temperature requirements before integration. Cross-reference datasheet revisions for any updates to electrical characteristics or packaging details.

Supervisors Selection Notes

Select this component when dual voltage monitoring is required with a fixed 2.93V threshold for the primary rail. The manual reset feature allows for external control over the reset state. Verify that the 0.3V secondary threshold meets the lowest monitored supply requirement. Confirm the SOT-23-5 package fits the design constraints.

Supervisors Part Context

This part belongs to the MIC2774 series of supervisory circuits designed for power management applications. It provides under-voltage detection and power-on reset generation. The series offers various threshold options and package types to suit different system architectures and space limitations.

Supervisors Replacement Considerations

Check for MIC2774L variants with similar thresholds such as MIC2774L-28YM5-TR or MIC2774L-29YM5-TR. Verify pin compatibility and electrical parameter alignment before substitution.
