LV8057GR
Overview
LV8057GR is single-chip motor driver IC for digital cameras.
Features
Integrates the digital camera actuator on a single-chip
PWM output with 3 channels and constant current output with 1.5 channel
All actuators can be driven at the same time (unusable for Shutter and Iris)
The AF stepping motor is driven by the clock signal
The PWM output can be set to one of 32 levels
The constant current output reference voltage can be set to one of 16 internal reference voltage levels
Built-in constant current output for LED drive with 1 channel (current value can be set to 16 levels)
Reduction of mounting area by adopting VCT28 package (3.5 × 3.5 mm)
