MIC2774L-26BM5

Supervisors Overview

The MIC2774L-26BM5 is a dual voltage supervisory circuit manufactured by Microchip Technology, formerly Micrel. It monitors two input voltages with thresholds of 0.3V and 2.67V. The device features an active-low push-pull output and manual reset capability. It operates within a supply voltage range up to 5.5V and includes a reset delay time of 140ms minimum. The component is housed in a SOT-23-5 package and supports surface mount installation.

Supervisors Feature Summary

• Dual-channel voltage supervision for independent monitoring of two distinct power rails
• Active-low push-pull output configuration for direct logic interface compatibility
• Manual reset functionality allowing user-initiated system recovery

Supervisors Applications

• Embedded systems requiring multi-rail power integrity monitoring
• Portable electronics utilizing low-voltage battery supplies
• Industrial control circuits needing reliable voltage supervision

Supervisors Procurement Notes

Verify the manufacturer status carefully as this specific part number (MIC2774L-26BM5) is listed as discontinued or obsolete by major distributors like DigiKey. Confirm availability through authorized channels or check for valid replacement part numbers such as the MIC2774L-26YM5-TR which offers similar specifications but may differ in suffix codes. Ensure RoHS compliance status matches project requirements before procurement.

Supervisors Selection Notes

Select this component when dual voltage monitoring is required with active-low outputs. Note that the 'B' suffix in the part number may indicate specific manufacturing or compliance variations compared to standard 'Y' suffix versions. Compare threshold voltages against system rail requirements to ensure proper supervision timing. Consider lead times and obsolescence status due to its discontinued nature.

Supervisors Part Context

This component belongs to the MIC2774 series of dual micro-power low voltage supervisors originally developed by Micrel Inc., now part of Microchip Technology. The series provides compact solutions for power management in space-constrained applications. The specific model integrates dual comparators and reference voltage sources into a single small outline transistor package.
