概述

Description

TC4427VOA is a dual, high‑speed MOSFET gate driver IC. It provides two independent, non‑inverting gate drivers with push‑pull outputs, capable of quickly charging and discharging MOSFET gates. Supplying from a typical 4.5–18 V (often 10–12 V for logic-level MOSFETs), it accepts TTL/CMOS logic inputs and translates them into appropriate gate voltages. Applications include driving MOSFETs in switching power supplies, DC‑DC converters, motor controllers, and class‑D audio amplifiers, especially where two gates (or a half‑bridge) need fast, coordinated switching. The suffix “VOA” indicates a specific packaging/temperature variant; check the datasheet for exact pinout, current capability, UVLO, propagation delays, and other electrical characteristics. In short: a compact dual-gate driver that boosts logic signals into fast, reliable MOSFET switching.

Features

Here are concise features for TC4427VOA:
- Dual, high-speed, non-inverting MOSFET driver
- Push-pull outputs; ~9 A peak source/sink per channel
- Wide supply range: 4.5 V to 18 V
- TTL/CMOS input compatible
- Fast propagation and rise/fall times
- Undervoltage lockout to protect operation
- Independent channels with low cross-talk
- 8-pin package; RoHS-compliant; suitable for wide temp ranges
Note: Exact numbers (current, delays, temperature range) may vary by package variant; refer to the specific datasheet for precise specs.

Package

TC4427VOA comes in an 8-pin SOIC (SOIC-8) package.

Pinout

- Pin count: 8 pins (SOIC-8/DIP-8).
- Function: Dual high-speed MOSFET gate driver with two independent channels; each input drives a corresponding push-pull output to drive MOSFET gates (inputs: IN1/IN2; outputs: OUT1/OUT2) from a single supply (Vcc) and ground (GND).

Manufacturer

Manufacturer: Toshiba (Toshiba Electronic Devices & Storage Corporation).
What kind of company: A Japanese multinational corporation that designs and manufactures electronics and semiconductors, including power devices and gate drivers.

Application

TC4427VOA is a dual high-speed, high-current MOSFET/IGBT gate driver. Applications: drive N-channel MOSFETs/IGBTs in switching regulators and PWM controllers (buck/boost/DC-DC converters), motor control (BLDC/stepper), power inverters (solar/UPS), Class D audio amplifiers, and general automotive/industrial gate-drive in power electronics. Features TTL/CMOS inputs, 4.5–18 V supply, fast rise/fall times, totem-pole outputs.
