LC898215XA Datasheet Af(auto Focus) Control Lsi

Manufacturer: onsemi

Overview: Ordering number : ENA2190 LC898215XA CMOS LSI AF(Auto Focus) Control LSI http://onsemi. Overview The LC898215 is a focus control LSI for cellphone/smartphone camera modules. It controls pre-loaded type actuators. The LSI is posed of a fast settling time circuit and a driver circuit to enable the control.

General Description

 I2C interface I2CCK I2CDT  Driver interface OUT1 ENA/OUT2  Power supply pin VDD GND B B O B P P LC898215XA I2C Clock pin I2C Data pin Actuator output pin LSI enable / Actuator output pin Power supply GND PIN TYPE “O”  Ensure that it is set to OPEN.

PIN TYPE “I”  OPEN is inhibited.

Ensure that it is connected to the VDD or VSS even when it is unused.

Key Features

  • the high speed movement completion of the actuator. Pre-loaded type actuators have unintentional oscillation by resonance frequency due to their structures while moving with step signal type current change, and it may interfere with the accurate focus control. This LSI's fast settling time circuit permits optimum control of the current change. It enables high speed movement completion of the actuator so that the circuit will be an effective function for configuring high speed focus control syste.
