The MIC4607 features adaptive dead-time circuitry which actively monitors key voltages in each of the three phases to minimize the dead-time between the high- and low-side transitions and antishootthrough circuitry, preventing erroneous inputs and noise from simultaneously turning on any of the three phase’s high- and low-side MOSFETs. The MIC4607 additionally features 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 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 ensures that the outputs are not aff ected 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 is available in a both a 28-pin 4mm × 5mm QFN and 28-pin TSSOP package with an operating junction temperature range of –40°C to +125°C.
