www.ti.com SNOSAV2C – APRIL 2006 – REVISED APRIL 2013 LM4570 Single-Ended Input Motor Driver
Check for Samples: LM4570 FEATURES 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. 1 2 Output Short Circuit Protection
