MIC4100/1
100V Half Bridge MOSFET Drivers General Description Features 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. Bootstrap supply max voltage to 118V DC Supply voltage up to 16V Drives high-and low-side N-Channel MOSFETs with
independent inputs CMOS input thresholds (MIC4100) TTL input thresholds (MIC4101) On-chip bootstrap diode Fast 30ns propagation times Drives 1000pF load with 10ns rise and fall times Low power consumption Supply under-voltage protection 3Ω pull up , 3Ω pull down output resistance Space saving SOIC-8L package –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 MIC4100/1 ensures 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 MIC4100 is available in the SOIC-8L package with a
junction operating range from –40°C to +125°C.
