MIC4223/4/5 Low-Side MOSFET Drivers

Dual 4 A, 4.5 V to 18 V, 15 ns Switch Time, Low-Side MOSFET Drivers with Enable - Available at Digi-Key

Micrel's MIC4223/4/5 Low-Side MOSFET DriversMicrel, Inc.'s MIC4223, MIC4224, and MIC4225 are a family of a dual 4 A, high-speed, low-side MOSFET drivers with logic-level driver enables. The devices are fabricated on Micrel's bipolar/CMOS/DMOS (BCD) process and operate from a 4.5 V to 18 V supply voltage. The devices parallel bipolar and CMOS output stage architecture provides high-current throughout the MOSFETs Miller region allowing the driver to sink and source 4 A of peak current from a 12 V supply and quickly charge and discharge a 2000 pF load capacitance in under 15 ns, while allowing the outputs to swing within 0.3 V of VDD and 0.16 V of ground.
