MIC2774H-22YM5-TR

Supervisors Overview

The MIC2774H-22YM5-TR is a dual voltage supervisor integrated circuit manufactured by Microchip Technology. It operates within a supply voltage range of 1.0V to 6.0V and features two independent monitoring channels with fixed thresholds of 0.3V and 2.25V. The device provides an active-high push-pull output for system reset control. It is housed in a compact SOT-23-5 surface-mount package, suitable for space-constrained designs.

Supervisors Feature Summary

• Dual-channel voltage supervision with distinct threshold settings
• Active-high push-pull output driver for direct logic interfacing
• Compact five-pin surface-mount packaging

Supervisors Applications

• Portable electronic devices requiring low-voltage monitoring
• Battery-powered systems needing power-fail detection
• Embedded controllers requiring brown-out protection

Supervisors Procurement Notes

Verify the specific suffix YM5 against the official datasheet to confirm pinout and electrical characteristics match the design requirements. Ensure the active-high output configuration aligns with the target microcontroller reset input polarity. Confirm RoHS compliance status through the manufacturer's current documentation before finalizing procurement.

Supervisors Selection Notes

Select this component when an active-high reset signal is required for dual-rail monitoring. Compare against the MIC2774N series if an open-drain output is preferred instead. Verify that the 2.25V threshold accurately covers the critical supply rail under all operating conditions and temperature ranges specified in the datasheet.

Supervisors Part Context

This part belongs to the MIC2774 family of dual voltage supervisors designed for portable applications. It complements other variants like the MIC2774L and MIC2774N, which differ primarily in output stage configuration and threshold options. The H-series designation specifically indicates the active-high push-pull output architecture.

Supervisors Replacement Considerations

MIC2774H-22BM5-TR is listed as a parameter-equivalent alternative.
