The MIC4607-1YTS-T5 is an 85V, three-phase MOSFET driver. The MIC4607-1YTS-T5 features a fast (35ns) propagation delay time and 20ns driver rise/fall times for a 1nF 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 MIC4607-1YTS-T5 includes overcurrent protection 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 MIC4607-1YTS-T5 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 MIC4607-1YTS-T5 is available in a both a 28-pin 4mm x 5mm QFN and 28-pin TSSOP package with an operating junction temperature range of -40°C to +125°C.
