概述

Description

MIC4426YM-TR is a dual, high-speed MOSFET gate driver from Microchip (Micrel). It provides two independent gate-drive channels with totem-pole outputs, designed to quickly charge and discharge external MOSFET gates. The inputs are compatible with TTL/CMOS logic, and the device operates from a single supply (typical range ~4.5–18 V). The YM packaging indicates an 8-pin package, and TR denotes Tape & Reel delivery. Typical applications include driving MOSFETs/IGBTs in switching power supplies, DC‑DC converters, motor drivers, and class-D audio amplifiers. In short, it’s a compact, fast, dual gate-driver ideal for improving switching performance in power electronics.

Features

Concise features of MIC4426YM-TR:
- Dual high-speed MOSFET gate drivers (two channels)
- Single-supply operation: 4.5 V to 18 V
- Push-pull outputs with high peak source/sink current (per channel)
- TTL/CMOS-compatible inputs
- Fast switching (high/low transitions for rapid gate drive)
- Internal undervoltage lockout (UVLO)
- Low quiescent current
- 8-pin package; YM variant (package style), TR = Tape & Reel packaging
Note: Use proper decoupling close to the device for best performance.

Package

8-pin surface-mount SOIC (Small Outline) package, Tape‑and‑Reel (TR) version.

Pinout

- Pin count: 8 pins (SOIC-8 package; TR denotes tape-and-reel)
- Function: Dual high-speed MOSFET gate driver. Two independent channels (IN1→OUT1 and IN2→OUT2) with a common VDD and GND, providing high-current, fast totem-pole outputs to drive MOSFET gates.

Manufacturer

- Manufacturer: Microchip Technology Inc. (the MIC4426/YM package was originally from Micrel; Microchip acquired Micrel in 2015).
- Company type: An American multinational semiconductor company that designs and manufactures microcontrollers, analog/mixed-signal ICs, memory, and related products.

Application

MIC4426YM-TR is a dual, high-speed MOSFET gate driver. Suitable for: driving power MOSFETs/IGBTs in switching power supplies and DC-DC converters; motor/drive circuits (half-bridge/full-bridge); Class D amplifiers; PWM switching applications needing fast, high-current gate drive with low propagation delay.

Equivalent

Direct equivalents (drop-in) are Microchip’s own TC4426/TC4427 (and TC4428) in the same family, pin-compatible with MIC4426YM-TR. Other vendors offer similar two-channel MOSFET drivers with comparable specs, such as TI UCC27211/UCC27212 (not pin-compatible). Always verify pinout, supply voltage range, and drive current in the datasheets.
