System LSIs for Blu-ray Drive
System Motor Driver IC
for Half Height Drive(Sensor less)
BD7763EFV
General Description
BD7763EFV are 9ch system motor driver ICs,
developed for the spindle motor, actuator coil,
stepping motor, SA stepping motor and the loading
motor drive of the Blu-ray drive. Since spindle
driver adopts sensor less drive system and the hall
sensor (3 pieces) of the motor position detection is
not needed, it is suitable for making of flexible
cable conserve wiring and the reductions of
external parts. The actuator, loading driver, the
spindle, stepping, and SA stepping use power
MOSFET to reduce power consumption.
Package(s)
HTSSOP-B54
18.5mm x 9.5mm x 1.0mm
Applications
For Blu-ray drive
Features
The hall sensor is not needed by 3-phase sensor less
drive system.
The spindle motor driver achieves stability high speed
start by ROHM's own energizing method.
Spindle, stepping and SA stepping achieve high
efficiency drive by PWM control driver. The actuator is
able to reduce power consumption by using PWM
drive system.
The loading adopts forward/reverse-rotation drive
system.
ON/OFF of loading and other channels, brake mode
of spindle driver, and stand-by mode are selectable by
the two control terminals.
Built-in thermal-shut down circuit.
Improved heat radiation efficiency utilizing lm-type
HTSSOP package with good thermal conductivity.
