Description

IR4322MTRPBF is a dual high-side/low-side gate-driver IC from Infineon/IR. It drives two MOSFETs in a half-bridge (two independent channels: HI/LI inputs with HO/LO outputs) and uses a bootstrap supply for the high-side. Typical uses include driving MOSFETs in switching regulators, DC-DC converters, motor drivers, and other power-supply topologies. Key features usually include undervoltage lockout, shoot-through prevention with dead-time control, and basic protection functions to improve reliability. The MTRPBF suffix denotes Pb-free packaging in a Tape & Reel format.

Features

IR4322MTRPBF is a dual MOSFET gate-driver IC with both high-side and low-side outputs. Key features include:
- Dual channel: HO (high-side) and LO (low-side) gate outputs
- Bootstrap high-side drive for full gate voltage above the switch node
- Independent inputs for HO and LO
- Undervoltage lockout (UVLO) on VCC and gate outputs
- Built-in dead-time to prevent shoot‑through
- Enable input for controlled startup/shutdown
- Fault/diagnostic feedback (status/flag reporting)
- Fast rise/fall times and strong gate-drive capability
- Protection features such as short-circuit/overcurrent and thermal protection
- Pb-free, tape-and-reel packaging (MTRPBF)
Designed for driving MOSFETs in switching regulators (e.g., multiphase buck converters) and other power‑conversion topologies.

Package

Package type: MTR package (Pb-free). The suffix TRPBF means Tape‑and‑Reel Pb‑free packaging.

Pinout

- Pin count: 16 pins
- Function: Dual high-side/low-side MOSFET gate driver (bridge/half-bridge driver) for driving two N-channel MOSFETs, with bootstrap capability and typical protection features for gate driving.

Manufacturer

- Manufacturer: Infineon Technologies (legacy brand International Rectifier).
- What kind of company: A global semiconductor company specializing in power electronics and power-management solutions (power MOSFETs, IGBTs, drivers, controllers, etc.).

Application

IR4322MTRPBF is a primary‑side regulation PWM controller for flyback topologies in offline switch‑mode power supplies. Typical applications:
- AC‑DC adapters and wall warts
- LED drivers with constant‑current output
- Battery chargers
- Compact isolated power supplies for consumer electronics, telecom, and industrial equipment
