Présentation

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.

Features

MIC4426YM-TR features (concise):
- Dual, non-inverting, high-speed MOSFET gate drivers
- Push-pull outputs; can source and sink high peak current to quickly charge/discharge gates
- Wide supply range: 4.5 V to 18 V
- TTL/CMOS-compatible inputs
- Suitable for driving N-channel MOSFETs directly (good for half-bridge/topologies)
- Low quiescent current
- Fast switching (propagation delays in tens of ns range, depending on load)
- 8-pin package; -TR denotes Tape & Reel packaging
Applications include switching regulators, motor drivers, and other high-speed gate-driving needs.

Pinout

- Pin count: 8 pins (8-pin package, e.g., SOIC/DIP).
- Function: Dual, high-speed MOSFET gate driver with two push-pull outputs to drive two MOSFET gates from TTL/CMOS inputs.

Manufacturer

- Manufacturer: Microchip Technology Inc. (the MIC4426 originated with Micrel; Microchip acquired Micrel).
- Kind of company: A global semiconductor company that designs, develops, and manufactures integrated circuits, including analog/mixed-signal ICs and microcontrollers.

Application

MIC4426YM-TR is a dual high‑speed MOSFET gate driver. Common applications:
- Gate drive for N‑channel MOSFETs/IGBTs in switching power supplies and DC‑DC converters
- Half‑bridge/full‑bridge motor controllers and inverters
- Power stages such as Class D amplifiers
- Logic buffering to microcontroller outputs to provide fast, high‑current gate charge/discharge
It provides fast edges and helps isolate the control logic from the gate, suitable for high‑speed switching applications with typical gate drive voltages in SMPS/topology designs.

Package

It uses an 8-pin SOIC (Surface-Mount) package; Tape & Reel (TR) packaging.
