LM4570 motor driver circuit The LM4570 is a single supply motor driver for improved sensory experience in mobile phones and other handheld devices. This device features Low Power Shutdown Mode, Minimum external components, Available in space-saving LLP package, Output Short Circuit Protection, Fast Turn on Time, High Output Current Capability, and Wide Output Voltage Range.

The following datasheet outlines detail information about LM4570 Motor Driver for Mobile Phones PDAs and Video Game Systems. It contains detail description, key specifications, features, applications, typical application, connection diagram, absolute maximum ratings, operating ratings, electrical characteristics, application information and physical dimension for the device.

The LM4570 uses a bridged architecture that drives a load differentially. The BTL design offers several advantages over a single-ended design. The the device  outputs, VO1 and VO2, both source and sink current, which means that the
polarity of the voltage across the motor can be reversed quickly.
