LC898113
CMOS LSI
Optical Image Stabilization (OIS)
Controller & Driver
www.onsemi.com
Overview
The LC898113 is device integrating digital gyro interface, gyro filter, stepping motor control circuit, and motor driver
functions needed to implement an Optical Image Stabilization (OIS) system using stepping motors. These functions
make it possible to build a system using a minimal software program that enables the host microcontroller to turn
Optical Image Stabilization (OIS) on and off, for example.
The gyro filter coefficients may be set to any values by the host microcontroller, making it possible to build filter
circuits optimized for the system. The LC898113 integrates a signal determination circuit for pan/tilt processing and a
filter circuit, enabling implementation of a variety of processing in response to camera movements.
The LC898113 integrates four saturation-drive H-bridge channels for stepping motor drive, and PWM drive with 1-2-
phase control to 8W1-2-phase control is supported.
Also integrated are a photo sensor drive circuit for control object position detection (for example, a CMOS sensor), a
position determination circuit, and a circuit for moving to the optical center based on the results from the preceding
circuits. Thus, the host microcontroller can specify detection start and the LC898113 will automatically move the
control object to the initial position.
Both SPI and I2C are supported as serial interfaces for communication with the host microcontroller. This allows the
customer to choose based on the specifications of the host microcontroller. The I2C interface also supports a 1.8 V
interface.
