The MIC4100 is a high-frequency 100V half-bridge MOSFET driver with independent high-side and low-side gate control, designed for driving N-channel MOSFETs in buck, push-pull, and full-bridge converters. It features CMOS input thresholds, an on-chip bootstrap diode, and a 30ns typical propagation delay with output rise and fall times of 10ns for a 1000pF load. The device operates from a 9V to 16V supply, supports bootstrap voltages up to 118V DC, and includes under-voltage protection on both drivers. Outputs have 3Ω pull-up and pull-down resistance. It is packaged in an SOIC-8L and rated for a junction temperature range of -40°C to +125°C.
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 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 MIC4100/1 helps ensure the outputs are not affected by supply glitches, HS ringing below ground, or HS slewing with high speed voltage transitions. Under-voltage protection is provided on both the low-side and high-side drivers. The MIC4100 is available in the SOIC-8L package with a junction operating range from -40°C to +125°C.
