LM4570 Single-Ended Input Motor Driver

April 2006

LM4570

Single-Ended Input Motor Driver

General Description

The LM4570 is a single supply motor driver for improved

sensory experience in mobile phones and other handheld

devices. The LM4570 is capable of driving up to 192mA

while operating from a 3V supply. Near rail-to-rail output

swing under load ensures sufficient voltage drive for most

DC motors, while the differential output drive allows the

voltage polarity across the motor to be reversed quickly.

Reversing the voltage gives the LM4570 the ability to drive a

motor both clock-wise and counter clock-wise from a single

supply.

The LM4570 features fast turn on time, and a wide input

voltage range for precise speed control. A low power shut-

down mode minimizes power consumption.

Thermal and output short circuit protection prevents the

device from being damaged during fault conditions.
