General Description
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.
The 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 VQFN package with wettable flanks in
Moisture Sensitivity Level 1. The operating junction
temperature range is between -40°C and +125°C.
