MIC4607A

The MIC4607A is an 85V, three-phase MOSFET driver. The MIC4607A 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 PWM input with high and low drive generated internally. High- and low-side outputs are guaranteed to not overlap in either mode. The MIC4607A includes overcurrent protection with blanking time insertion as well as a high-voltage internal diode that charges the high-side gate drive bootstrap capacitor. A robust, high-speed, and low-power level shifter provides clean level transitions to the high-side output. The robust operation of the MIC4607A ensures that the outputs are not affected by supply glitches, HS ringing below ground, or HS slewing with high-speed voltage transitions. Undervoltage protection is provided on both the low-side and high-side drivers. The MIC4607A is available in a 28-pin 4 mm x 5 mm QFN package with wettable flanks in Moisture Sensitivity Level 1. The operating junction temperature range is between -40°C and +125°C.
