Low-side driver IC enables fast switching speeds
International Rectifier
AUIRS4427S driver IC
International Rectifier has introduced the AUIRS4427S dual low-side driver IC for low-, mid- and high-voltage automotive applications.
The AUIRS4427S is a low-voltage, high-speed power Mosfet and IGBT driver qualified to AEC-Q100 standards.
The output drivers feature a high pulse current buffer stage for minimum driver cross-conduction and matched propagation delay for both channels.
Negative voltage spike (Vs) immunity is provided to protect against catastrophic events during high-current switching and short-circuit conditions.
With its benchmark negative voltage spike immunity and matched propagation delay, the AUIRS4427S is a rugged dual low-side driver that enables fast switching speeds, making the device suitable for high-power DC-DC converters and powertrain applications.
The AUIRS4427S, which is 3.3V and 5V logic compatible with standard CMOS or LSTTL output, features gate voltage (VOUT) up to 20V, CMOS Schmitt-triggered inputs, two independent gate drivers and outputs in phase with inputs.
