LC898214XC: Auto Focus (AF) Controller
LC898214XC is an all-in-one type auto-focus driver that integrates current driver, control logic, Hall-sensor, and EEPROM.
This driver achieves <3ms auto focus settling time and serves low power consumption & space saving.
This driver is suitable for smaller camera module.
