μ-step System Lens Driver
for Digital Still Cameras
BU24024GU
General Description
BU24024GU 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.

Description of Blocks
Current Driver (7ch Driver)
Built-in constant current driver.
The voltage of RNF pin and the external resistor (RRNF) determine the amount of output current. The internal
high-precision amplifier (CMOS gate input) is used for constant current control. If any resistance component exists in
the wirings of RNF pin and the external resistor (RRNF), the precision can be reduced. To avoid this, pay utmost
attention to the wirings.
(1) Control
() Register Control
The constant current drive is executed by the output current value, the current direction and the current ON/OFF which
are controlled by the register settings.

()External Pin Control
The constant current drive is executed by the output current value which is controlled by the register setting. Constant
