MIC4604
Description
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 1n F 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.
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 × 2.5mm TDFN package. Both packages have an operating junction temperature range of
- 40°C to +125°C.
