MIC4604
85V Half Bridge MOSFET Drivers with up to
16V Programmable Gate Drive General Description Features The MIC4604 is an 85V Half Bridge MOSFET driver. The
MIC4604 features fast 39ns propagation delay times and
20ns driver rise/fall times for a 1nF capacitive load. The
low-side and high-side gate drivers are independently
controlled. The MIC4604 has TTL input thresholds. It
includes a high-voltage internal diode that helps charge
the high-side gate drive bootstrap capacitor. 5.5V to 16V gate drive supply voltage range. Drives high-side and low-side N-Channel MOSFETs
with independent inputs TTL input thresholds On chip bootstrap diode Fast 39ns propagation times Drives 1000pF load with 20ns rise and fall times Low power consumption Supplies undervoltage protection –40°C to +125°C junction temperature range A robust, high-speed, and low-power level shifter provides
clean level transitions to the high-side output. The robust
operation of the MIC4604 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 MIC4604 is available in an 8-pin SOIC package and a
tiny 10-pin 2.5mm Г— 2.5mm TDFN package. Both
packages have an operating junction temperature range of
–40°C to +125°C.
