Dual-Phase MOSFET Drivers

with Temperature Sensor

General Description

Features

The MAX8702/MAX8703 dual-phase noninverting

MOSFET drivers are designed to work with PWM con-

troller ICs, such as the MAX8705/MAX8707, in note-

book CPU core and other multiphase regulators.

Applications can either step down directly from the bat-

tery voltage to create the core voltage, or step down

from a low-voltage system supply. The single-stage con-

version method allows the highest possible efficiency,

while the 2-stage conversion at higher switching frequen-

cy provides the minimum possible physical size.

ꢀ Drives Large Synchronous-Rectifier MOSFETs

ꢀ Integrated Temperature Sensor (MAX8702 Only)

Resistor Programmable

Open-Drain Driver Hot Indicator (DRHOT)

ꢀ Adaptive Dead Time Prevents Shoot-Through

ꢀ Selectable Pulse-Skipping Mode

Each MOSFET driver is capable of driving 3nF capaci-

tive loads with only 19ns propagation delay and 8ns

typical rise and fall times. Larger capacitive loads are

allowable but result in longer propagation and transition

times. Adaptive dead-time control helps prevent shoot-

through currents and maximizes converter efficiency.

ꢀ 4.5V to 28V Input Voltage Range

ꢀ Thermally Enhanced Low-Profile Thin QFN Package

Ordering Information

The MAX8702/MAX8703 feature zero-crossing com-

parators on each channel. When enabled, these com-

parators permit the drivers to be used in pulse-skipping

operation, thereby saving power at light loads. A sepa-

rate shutdown control is also included that disables all

functions, drops quiescent current to 2µA, and sets DH

low and DL high.
