Overview

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