Microchip | MIC4100YM-TR

The MIC4100YM TR is a high frequency, 100 V Half Bridge MOSFET driver ICs featuring fast 30 ns propagation delay time. The low-side and high-side gate drivers are independently controlled and matched to within 3 ns 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 ensures 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.
