LB8650T ^{Monolithic Digital IC}
Driver for Digital Still Cameras
Overview
LB8650T is a driver for digital still cameras.
Features
• Two direct nickel hydride batteries for digital cameras embedded in one chip.
(1) Constant voltage control for AF - Stepping motor driver.
1-2 phase excitation, 2 phase excitation possible.
(2) Constant current control for SH - Solenoid coil driver → Built-in start-up correction circuit.
• No standby current consumption (or zero).
• Low voltage driving possible (1.9V to).
• Low saturation output.
• Built-in thermal protection circuitry.
