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.

Applications

• Power inverters

The MIC4604 is available in an 8-pin SOIC package and a

tiny 10-pin 2.5mm × 2.5mm TDFN package. Both

packages have an operating junction temperature range of

–40°C to +125°C.

• High-voltage step-down regulators

• Half, full and 3-phase bridge motor drives

• Distributed power systems

• Computing peripherals
