IR21844STRPBF

Overview

The IR21844STRPBF is a high-voltage, high-speed power MOSFET and IGBT driver with independent high-side and low-side referenced output channels. Designed for bootstrap operation, it supports floating channels up to +600V and provides 1.4A source and 1.8A sink current capabilities.

Why Choose This Part

This driver features excellent dV/dt immunity and a high tolerance for negative transient voltages, ensuring robust operation in noisy industrial environments. The integrated programmable deadtime and matched propagation delays help prevent shoot-through current and improve overall system efficiency.

Applications

Getting Started

When designing with this IC, ensure the bootstrap capacitor is sized to supply the high-side gate charge and include a high-speed diode. Layout is critical; minimize the loop area between the gate driver outputs and the MOSFET gates to reduce parasitic inductance and ringing.
