MIC4102
100V Half Bridge MOSFET Driver
with Anti-Shoot Through Protection
PRELIMINARY SPECIFICATIONS
General Description
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.
Under-voltage protection on both the low-side and high-
side supplies forces the outputs low. An on-chip boot-strap
diode eliminates the discrete diode required with other
driver ICs.
The MIC4102 is available in the SOIC-8L package with a
junction operating range from –40°C to +125°C.

Micrel’s web site at www.micrel.com.
