Product details

Dual-voltage supervisor in a five-pin SOT-23

The MIC2774N-46YM5 is a dual micro-power low-voltage supervisor from Microchip Technology, monitoring two supply rails with a single active-low reset output.

Package and temperature grade for embedded designs

Housed in a SOT-23-5 (SC-74A) package, the supervisor occupies minimal board area and suits space-constrained designs like sensor nodes, industrial controllers, or portable instrumentation. The surface-mount footprint is standard for five-pin SOT-23 — no special layout rules beyond placing the bypass capacitor close to the supply pin.

Frequently asked questions

What does the 4.68 V threshold mean for a 5 V rail?

The 4.68 V threshold triggers a reset when the 5 V supply drops approximately 6.4% below nominal — typical for monitoring a 5 V ±5% rail where the supervisor must assert reset before the logic supply falls out of regulation.

What is the closest pin-compatible alternative to MIC2774N-46YM5?

The MIC2774 family shares the same pinout but different threshold options; verify the voltage code before substituting.

What compliance documentation does Microchip provide for MIC2774N-46YM5?

The part is RoHS-compliant per Microchip's standard material declaration. No UL or IEC certification is listed for this device; the datasheet covers operating ratings and absolute maximums.
