General Description

The MIC4100 and MIC4101 are high frequency, 100V

half-bridge MOSFET driver ICs that feature fast 30 ns

propagation delay times. 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 ensure 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 MIC4100/1 is available in the 8-lead SOIC

package with a junction operating range from

–40°C to +125°C.
