Descripción de LM4570
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.
