Supports simultaneous drive of multiple actuators
Five independent power supply systems (focus, shutter, aperture, zoom, and control)
Supports low-voltage operation (from 1.9V)
Low saturation voltage outputs (Vsat = 0.3V typical at IO = 200mA)
Zero current consumption in standby mode
Built-in thermal protection circuit
Miniature, thin-form packages. LB8656FN : VQFN48 (7×7), LB8656W : SQFP48 (7×7)
