LC898217XH
Auto Focus (AF) Controller & Driver
1. Overview
LC898217XH is the AF control LSI. It consists of 1 system of feedback
circuit for AF control. Built-in equalizer circuit using digital operation.
Built-in A/D converter, D/A converter, Constant Current Driver.
LC898217XH contains an internal EEPROM. It easily accomplishes
Hall calibration and power-on sequence. Also LC898217XH has fast
settling function for quickly moving focus lens. This is suitable for
small & thinner camera module.

* Process when pins are not used
PIN TYPE “O” Ensure that it is set to OPEN.
PIN TYPE “I” OPEN is inhibited. Ensure that it is connected to the V

SS
even when it is unused.
(Please contact ON Semiconductor for more information about selection of V

.)
PIN TYPE “B” If you are unsure about processing method on the pin description of pin layout table, please contact us.
Note that incorrect processing of unused pins may result in defects.
* In case of connecting PORT pin with HOST CPU
When LC898217XH is power off and HOST CPU is power on, a HOST CPU pin connected with PORT pin have to be
fixed "L" level.
