UP6281 PDF Datasheet – 12V MOSFET Driver

A MOSFET driver is a specialized integrated circuit (IC) designed to provide the necessary electrical signals to drive metal-oxide-semiconductor field-effect transistors (MOSFETs) efficiently and effectively. MOSFETs are commonly used as electronic switches in a wide range of applications, including power electronics, motor control, voltage regulation, and more. A MOSFET driver ensures that the MOSFET is turned on and off rapidly and reliably, optimizing its performance and minimizing switching losses.

Description

The UP6281 is a dual, high voltage MOSFET driver optimized for driving two N-Channel MOSFETs in a synchronousrectified buck converter. Each driver is capable of driving a 5000pF load with 30ns transition time. This device combined with uPI multi-phase buck PWM controller forms a complete
core voltage regulator for advanced micro-processors.

The uP6281 features adaptive anti-shoot-through protection that prevents cross-conduction of the external MOSFET while maintains minimum deadtime for optimized efficiency. Both gate drives are turned off by pulling low OD# pin or high-impedance at PWM pin, preventing rapid output
capacitor discharge during system shutdowns […]
