12V MOSFET Drivers with Output Disable for Multi-Phase

Synchronous-Rectified Buck Converter

Features

General Description

The uP1989 is a dual, high voltage MOSFET driver optimized All-In-One Synchronous Buck Drivers

for driving two N-channel MOSFETs in a synchronous-

Integrated Bootstrap Switch

rectified buck converter. Each driver is capable of driving a

Integrated Gate-to-Source Discharge Resistors

5000pF capacitive load with 30ns transition time. This

Anti-Shoot-Through Protection Circuitry

device combined with uPI multi-phase buck PWM controller

Tri-State Input for Bridge Shutdown

forms a complete core voltage regulator for advanced micro-

processors.

Output Disable Control Turns Off both MOSFETs

The uP1989 features anti-shoot-through protection that Under Voltage Lockout for Supply Input

prevents cross-conduction of the external MOSFET while

maintains minimum deadtime for optimized efficiency.

High-Side MOSFET Short Power on Protection

Allow PWM Pin as Multi-Function Setting

This part has integrated bootstrap switch to help minimize

the external component count. Both gate drives are turned

off by pulling low EN pin or high-impedance at PWM pin,

preventing rapid output capacitor discharge during system

shutdown.

Application

VQFN4x4-24L Package

RoHS Compliant and Halogen Free

Applications

This device also supports supply input under voltage

lockout. The uP1989 is available in a thermally enhanced

VQFN4x4-24L package.
