LB8682PL
Overview
Monolithic Digital IC
For Camera Cell Phone Motor Driver
Two Saturated Drive Channels and One Constant-Current Drive Channel
The LB8682PL is a motor driver IC that has a two saturated drive channels and one constant-current drive channel. Its compact, low-profile package makes it ideal for use in cell phone cameras. Using direct microcontroller drive, and the control of the shutter and the motor for the AF(Auto-Focus) drive, etc..
Functions
* Constant voltage control for AF (H-Bridge x 2ch) * Constant current control for shutter. (H-Bridge x 1ch) * Built-in thermal protection circuit * Built-in reference voltage circuit (0.2V typical) * Built-in spark killer diodes

Usage Notes
* The constant-current level is set with the resistor RF. The formula for calculating the current is shown below. Constant-current level = 0.2 / RF * Connect capacitors between VCC and ground to reduce the amount of motor noise that enters the power supply.
