Microchip Technology, Inc. 100V Half Bridge MOSFET Driver MIC4104

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 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 MIC4103 and MIC4104 are available in an 8-lead SOIC package with a operating junction temperature range of -40°C to +125°C.
