BU24036MWV
●General Description
BU24036MWV 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
moor 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-4ch: Voltage control type H-bridge
(Adaptable to STM 2systems)
5ch: Voltage / Current control type H-bridge
6ch: Current control type H-bridge
 Built-in 2 channels PI driving circuit
 Built-in 1 channels Waveforming circuit
 Built-in FLL digital servo circuit
 Built-in PLL circuit
 Built-in STM control circuit : Autonomous control
(cache / updown mode), Clock IN control
