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.
