μ-step System Lens Driver
for Digital Still Cameras
BU24032GW
●General Description BU24032GW is a system Lens Driver that uses μ-step driving to make the configuration of the sophisticated, high precision and low noise lens driver system possible. This IC has a built-in driver for both DC motor and voice coil motor and a μ-step controller that decreases CPU power. Therefore, multifunctional lens can be applied.
●Features Built-in 6 channels Driver block 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
