Dual Low-Side Driver IC Is Automotive Qualified

The AUIRS4427S is a low-voltage, high-speed power MOSFET and IGBT driver qualified to AEC-Q100 standards. The dual low-side driver IC is suitable for low-, mid-, and high-voltage automotive applications, including general-purpose motor drives, automotive dc-dc converters, and hybrid powertrain drives. The output drivers feature a high-pulse-current buffer stage for minimum driver cross-conduction and matched propagation delay for both channels. The driver provides negative voltage spike (VS) immunity to protect against catastrophic events during high-current switching and short-circuit conditions. The device, which is 3.3-V and 5-V logic compatible with standard CMOS and LSTTL output, features gate voltage (VOUT) of up to 20 V, CMOS Schmitt-triggered inputs, two independent gate drivers, and outputs in phase with inputs. Available in an 8-pin SOIC package, pricing for the AUIRS4427S begins at $0.51 each in 100,000-unit quantities. Production orders are available immediately.
