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. www.DataSheet4U.com 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.
