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.

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

with other driver ICs.

The MIC4102 is available in the SOIC-8L package with

a junction operating range from –40°C to +125°C.
