Microchip | MIC4225YM-TR

The MIC4225YM TR is a part of MIC422x series dual 4 A, High-Speed, Low-side MOSFET driver with logic-level driver enable.

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 4A of peak current from a 12 V supply and quickly charge and discharge a 2000 pF load capacitance in under 15ns, while allowing the outputs to swing within 0.3 V of V DD and 0.16V of ground.
