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

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

(1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for
which the device is functional, but do not specify specific performance limits. Electrical Characteristics state DC and AC electrical
specifications under particular test conditions which specify specific performance limits. This assumes that the device is within the
Operating Ratings. Specifications are not specified for parameters where no limit is given; however, the typical value is a good indication
of device performance.
(2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and
specifications.
(3) All voltages are measured with respect to the ground pin, unless otherwise specified.
(4) The maximum power dissipation must be de-rated at elevated temperatures and is dictated by TJMAX, θJC, and the ambient temperature
TA. The maximum allowable power dissipation is PDMAX = (TJMAX –TA)/ θJA or the number given in the Absolute Maximum Ratings,
whichever is lower. For the LM4570, TJMAX = 150°C and the typical θJA for the WSON package is 140°C/W.
(5) Human body model, 100pF discharged through a 1.5kresistor.
(6) Machine Model, 220pF–240pF discharged through all pins.
