LB8648T
Feature and functions
Monolithic Digital IC
DSC Driver
• Actuator driver for digital cameras embedded in one chip 1. Constant current control for AF (auto focus) Stepping motor × 1 → 1-2 phase, 2 phase excitation possible. 2. Constant current control for SH (shutter)/AE (aperture) VCM (Voice Coil Motor) × 2 → SH implements start-up/falling correction circuit. 3. Constant voltage control for ZOOM DC motor × 1 → Operation by direct battery connection. • Stand-by current consumed is 0 (zero). • 2 power source systems (direct source connection, DC/DC systems) • Large working voltage range (2.2 to 9V). • Low saturation output • Built-in overheat protection circuitry
Absolute Maximum Ratings at Ta = 25°C
Parameter Max.
