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 out-

puts are guaranteed to not overlap in either mode.

The MIC4607A includes overcurrent protection with

blanking time insertion as well as a high-voltage inter-

nal diode that charges the high-side gate drive boot-

strap 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.
