MIC4100 - 100V Half Bridge MOSFET Drivers

General Description

The MIC4100/1 are high frequency, 100V Half Bridge MOSFET driver ICs featuring fast 30ns propagation delay times.

The low-side and high-side gate drivers are independently controlled and matched to within 3ns typical.

The MIC4100 has CMOS input thresholds, and the MIC4101 has TTL input thresholds.

MIC4100/1 www.DataSheet4U.com 100V Half Bridge MOSFET Drivers General Description The MIC4100/1 are high frequency, 100V Half Bridge MOSFET driver ICs featuring fast 30ns propagation delay times. The low-side and high-side gate drivers are independently controlled and matched to within 3ns typical. The MIC4100 has CMOS input thresholds, and the MIC4101 has TTL input thresholds. The MIC4100/1 include a high voltage internal diode that charges the highside 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 MIC4100/1 ensures the outputs are not affected by supply glitches, HS ringing below ground, or HS slewing with high speed voltage transitions.
