MIC4103/4104
100V Half Bridge MOSFET Drivers
3/2A Sinking/Sourcing Current
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. Under-
voltage protection is provided on both the low-side and
high-side drivers.
The MIC4103 and MIC4104 are available in an 8-pin SOIC
package with a operating junction temperature range of –
40°C to +125°C.
