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 clockwise
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 shutdown
mode minimizes power consumption.
Thermal and output short circuit protection prevents the device
from being damaged during fault conditions.
