Features General Description Drives High-and Low-Side N-Channel MOSFETs
with Single Input Adaptive Anti-Shoot-Through Protection Low-Side Drive Disable Pin Bootstrap Supply Voltage to 118V DC Supply Voltage up to 16V TTL Input Thresholds On-Chip Bootstrap Diode Fast 30 ns Propagation Times Drives 1000 pF Load with 10 ns Rise and Fall
Times Low Power Consumption Supply Undervoltage Protection 2.5Ω Pull-Up, 1.5Ω Pull-Down Output Resistance Space Saving SOIC-8L Package –40°C to +125°C Junction Temperature Range The MIC4102 is a high frequency, 100V half-bridge
MOSFET driver IC featuring internal anti-shoot-through
protection. The low-side and high-side gate drivers are
controlled by a single input signal to the PWM pin. The
MIC4102 implements adaptive anti-shoot-through
circuitry to optimize the switching transitions for
maximum efficiency. The single input control also
reduces system complexity and greatly simplifies the
overall design.
The MIC4102 also features a low-side drive disable
pin. This gives the MIC4102 the capability to operate in
a non-synchronous buck mode. This feature allows the
MIC4102 to start up into applications where a bias
voltage may already be present without pulling the
output voltage down.
Undervoltage protection on both the low-side and
high-side supplies forces the outputs low. An on-chip
bootstrap diode eliminates the discrete diode required …
