System Lens Drivers
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
●Applications
Digital still cameras

●Description of Blocks
Voltage Driver (3ch-5ch Driver)
Built-in voltage driver of PWM driving type.
4ch/5ch driver is the exclusive driver.
Built-in digital FLL speed control logic for 5ch driver.
(１)Control
(ⅰ)Register Control
■3ch Driver, 4ch Driver, 5ch Driver (at speed control = OFF)
The PWM drive is executed by the PWM duty ratio, the PWM direction and the PWM ON/OFF which are controlled by
the register settings.

■5ch Driver (at speed control = ON)
The speed control drive is executed by the target speed value, the direction, the coefficient value of PI filter and the
turning ON/OFF which are controlled by the register settings.
The motor speed is adjusted by comparing the target speed with the motor speed detected at the signal of
photo-interrupter.
