Infineon Technologies IRS2332STRPBF

Overview

IRS2332STRPBF from Infineon Technologies is a high-voltage, high-speed 6-channel gate driver IC for half-bridge configurations, featuring 600 V high-side and low-side output capability, 200 ns typical propagation delay, and integrated bootstrap diodes. It drives N-channel MOSFETs or IGBTs in motor control inverters and industrial power supplies.

For engineers reviewing the IRS2332STRPBF datasheet, IRS2332STRPBF pinout, IRS2332STRPBF application, or IRS2332STRPBF equivalent, key selection criteria include high-side floating supply tolerance, independent channel enable logic, thermal shutdown flag output, and SOIC-28 package compatibility with PCB layout constraints for high dv/dt immunity.

Technical Context

The IRS2332STRPBF integrates six independent gate drivers-three high-side (HIN1–HIN3) and three low-side (LIN1–LIN3)-with level-shifted high-side channels capable of operating up to 600 V referenced to VS. Each channel delivers ±250 mA peak source/sink current and supports PWM input frequencies up to 100 kHz.

It features undervoltage lockout (UVLO) on both VCC (10–20 V) and VB (10–20 V), a dedicated fault reporting pin (FAULT#) that asserts low on overcurrent or UVLO, and internal bootstrap diodes eliminating external diode placement for each high-side channel.

Key Specifications

Pinout & Package

IRS2332STRPBF is housed in a 28-pin SOIC wide-body package (SOIC-28W) with 1.27 mm pitch, designed for creepage/clearance compliance in 600 V systems. The exposed pad variant is not present; thermal dissipation relies on PCB copper area under the package body.

FAQ

What is the maximum recommended switching frequency for IRS2332STRPBF?

The IRS2332STRPBF supports PWM frequencies up to 100 kHz, limited by its 200 ns propagation delay and ±250 mA drive strength. At 100 kHz, gate charge delivery remains effective for MOSFETs with ≤1.5 nF total gate capacitance. Higher frequencies increase switching losses and require tighter layout control to maintain timing integrity.

Does IRS2332STRPBF include built-in shoot-through protection?

No, IRS2332STRPBF does not implement hardware interlock or shoot-through prevention logic. Its HIN/LIN inputs are fully independent, requiring external dead-time generation in the controller (MCU/FPGA). This design preserves timing flexibility but places responsibility for safe switching sequence on the system-level firmware or logic.

Can IRS2332STRPBF drive IGBTs and MOSFETs interchangeably?

Yes - IRS2332STRPBF is optimized for both N-channel IGBTs and MOSFETs. Its ±250 mA peak current and 200 ns propagation delay suit typical 1200 V/30 A IGBTs and 600 V/50 A MOSFETs used in 3-phase inverters. Gate resistor selection must be adjusted per device Qg to balance switching speed and EMI.

Is thermal derating required for continuous operation at 600 V bus voltage?

Yes - at full 600 V bus and 100 kHz switching, junction temperature rise depends on PCB copper area and ambient airflow. With 2 cm² of 2-oz copper under the SOIC-28W package and 200 LFM airflow, derating begins above 75°C ambient. Thermal shutdown activates at 150°C junction temperature to prevent damage.
