System Lens Drivers
μ-step System Lens Driver
for Digital Still Cameras
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

●Description of Blocks
Voltage / Current Driver (5ch Driver)
Built-in voltage driver of PWM driving type / constant current driver.
Built-in digital FLL speed control logic for voltage driver.
(1) Control
(ⅰ)Register Control
■Voltage 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.

■Voltage 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.
