MIC4104

MIC4103/4104 www.DataSheet4U.com 100V Half Bridge MOSFET Drivers 3/2A Sinking/Sourcing Current PRELIMINARY General Description The MIC4103 and MIC4104 are high frequency, 100V Half Bridge MOSFET drivers with faster turn-off characteristics than the MIC4100 and MIC4101 drivers. They feature fast 24ns propagation delay times and 6ns driver fall times. The low-side and high-side gate drivers are independently controlled and matched to within 3ns typical. The MIC4103 has CMOS input thresholds and the MIC4104 has TTL input thresholds. The MIC4103/4 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 MIC4103/4 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 MIC4103 and MIC4104 are available in an 8-pin SOIC and 8-pin 3mm × 3mm MLF® package with a operating junction temperature range of –40°C to +125°C.
