Overview

The ISO5452DWR is a reinforced isolated single-channel gate driver designed for IGBTs and MOSFETs with a 5700Vrms isolation rating. It features integrated protection mechanisms including desaturation (DESAT) detection, a Soft Turn-Off (STO) function, and an active Miller clamp to prevent parasitic turn-on in high dV/dt environments. The device utilizes capacitive coupling technology to provide high electromagnetic immunity and low propagation delay.

Why Choose This Part

This driver offers a high peak output current of up to 5.5A for turn-off, reducing switching losses in large power modules. The integrated Active Miller Clamp eliminates the need for negative gate drive in many applications, while the Soft Turn-Off feature protects the power stage from overvoltage spikes during short-circuit conditions.

Applications

Industrial Motor Drives
Providing isolated high-side and low-side gate drive for AC brushless and DC motor control systems.
Solar Inverters
Managing power switching in string inverters where high transient immunity and isolation are critical.
Uninterruptible Power Supplies (UPS)
Ensuring reliable switching in high-power UPS stages with integrated fault reporting via the FAULT output.
EV Charging Stations
Used in high-voltage DC fast chargers to provide safety isolation between the controller and power stages.

Getting Started

Designers should evaluate the ISO5452DWR using the ISO5452EVM evaluation module to verify timing and protection thresholds. Ensure that the VCC2 supply is decoupled with low-ESR capacitors placed close to the pins and follow strict creepage and clearance layout guidelines for the 16-SOIC package to maintain 5700Vrms isolation integrity.
