Microchip MIC4607A

Microchip’s MIC4607A is an 85V, three-phase MOSFET driver. It features a fast (35 ns) propagation delay time and a 20 ns driver rise/fall time for a 1 nF capacitive load. TTL inputs can be separate, high- and low-side signals or a single Pulse-Width Modulation (PWM) input with high and low drive generated internally. High- and low-side outputs do not overlap in either mode. The MIC4607A is available in a 28-pin, 4 mm × 5 mm VQFN package with wettable flanks in Moisture Sensitivity Level 1.
