μ-step System Lens Driver
for Digital Still Cameras
BU24038GW
●General Description BU24038GW 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 9 channels Driver block 1ch-8ch:
Voltage control type H-bridge (Adaptable to STM 3systems) 9ch: Current control type H-bridge Built-in 3 channels PI driving circuit Built-in 4 channels Waveforming circuit Built-in PLL circui...
