Description
MIC4426YM-TR is a dual, high-speed MOSFET gate driver from Microchip (Micrel). It provides two fast, push-pull outputs to drive external MOSFET gates, enabling rapid charging/discharging and improved switching efficiency in power conversion, motor drives, and Class-D audio amplifiers.
Key points:
- Dual gate-driver: two independent outputs for two MOSFETs
- Input: TTL/CMOS-compatible logic
- Output: high-current, low-impedance push-pull
- Supply: single-supply operation (typical 4.5–18 V) for logic and gate drive
- Protection: undervoltage/logic safeguards to keep outputs off when supply is low
- Packaging: YM variant in a small 8-pin package; TR denotes tape-and-reel shipping
Applications include DC-DC converters, motor drivers, half-bridge/topology drivers, and other switching power applications. For exact electrical specs (current, delays, UVLO thresholds), consult the MIC4426YM-TR datasheet.

Equivalent
Direct equivalents (drop-in) for MIC4426YM-TR are TI’s TC4426 and TC4427 dual high-speed MOSFET gate drivers. They share the same 4.5–18 V supply range and about 6 A peak output. Other vendors offer similar two-channel gate drivers; always verify pinout, drive current, and package before substitution.
