Datasheet System Lens Drivers -step System Lens Driver for Digital Still Cameras BU24032GW General Description Key Specifications Digital Power Supply Voltage: 2.7V to 3.6V BU24032GW is a system Lens Driver that uses -step Driver Power Supply Voltage: 2.7V to 5.5V driving to make the configuration of the sophisticated, Output Current (1ch-5ch): 500mA(Max) high precision and low noise lens driver system possible. Input Clock Frequency: 1MHz to 28MHz This IC has a built-in driver for both DC motor and voice FET ON Resistance (1ch-5ch): 2.0 (Typ) coil motor and a -step controller that decreases CPU FET ON Resistance (6ch): 1.0(Typ) power. Therefore, multifunctional lens can be applied. Operating Temperature Range: -20 to +85 Features Package Built-in 6 channels Driver block UCSP75M2 2.50mm x 2.50mm x 0.85mm 1ch-5ch: Voltage control type H-bridge (Adaptable to STM 1systems) 6ch: Current control type H-bridge Built-in 2 channels PI driving circuit Built-in 3 channels Waveforming circuit Built-in FLL digital servo circuit Built-in PLL circuit Applications Digital still cameras Typical Application Circuit Example1 Photo interrupter DVDD VDDAMP MVCC12 DVSS MVCC345 OUT3A 3ch Driver MGND126 OUT3B MGND345 OUT4A Logic OUT4B/5B 4ch/5ch OUT1A Driver OUT5A 1ch M Driver OUT1B OUT2A RNF6 2ch Driver OUT2B OUT6A 6ch Driver OUT6B Main Host Product structureSilicon monolithic integrated circuit This product is not designed for protection against radioactive rays . www.rohm.com TSZ02201-0M2M0BC12060-1-2 2013 ROHM Co., Ltd.
