LV8080LP: Motor Driver, 2-Channel, H-Bridge, Constant Current

The LV8080LP is a two-channel, constant-current driver that supports low-voltage operation. It is optimal for constant-current drive of stepping motors (AF and zoom) in portable equipment such as camera cell phones and security cameras.

Features

Built-in thermal protection and low-voltage sensing circuits
Integrated power supply SW and detection comparator
Constant current drive for battery device
Two channels constant-current H-bridge driver
Built-in power supply switch and position detection comparator for use with a photoreflector
Implemented in a low-power MOS IC process.
Ultraminiature easy to solder VCT16 package (2.6 2.6mm)
Supports both 2-phase drive and 1-2 phase drive.
Low Voltage Operation 2.5Vmin
Built-in switching device for stand-by Current saving for photo reflector.

Benefits

Thermal protecton, Low voltage detection
Fewer external components
Low input voltage 2V available
