LB8684CL
Monolithic Digital IC
Digital Camera Motor Driver
for Cell Phones
Overview
The LB8684CL is a low-voltage, low-saturation 1.5-channel constant current forward/reverse driver IC provided in a
miniature package suitable for use in cell phone cameras. The LB8684CL can be driven directly from a microcontroller
and is optimal for control of the voice coil motors used for shutter and aperture control in cell phone cameras.
Features
• Supports low-voltage drive. (2.2V or more)
• Ultraminiature package (ECSP2828-12)
Functions
• Constant current control (IOUT = 100mA at RF = 2Ω)
• Built-in thermal protection circuit
• Built-in reference voltage (0.2V typical)
• Built-in spark killer diode
• ENA input logic (3-port interface)
