LM4570 Datasheet Single-ended Input Motor Driver

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LM4570 Single-Ended Input Motor Driver April 2006 LM4570 Single-Ended Input Motor.

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.

Key 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.
