µPD16882
MONOLITHIC CD-ROM/DVD-ROM 3-PHASE SPINDLE MOTOR DRIVER
DESCRIPTION
The µPD16882 is a CD-ROM/DVD-ROM 3-phase spindle motor driver consisting of a CMOS controller and MOS
bridge outputs.
By employing 3-phase full-wave PWM as the drive method and MOSFETs at the output stage, it has been
possible to reduce the power consumption of the µPD16882 ever further than the drivers that use bipolar transistors.
By using a 30-pin shrink SOP package, a more compact-size has been achieved.

7. FUNCTION OPERATION TABLE
(1) ST/SP (start/stop) function
Turning ON/OFF the spindle can be controlled by the ST/SP pin while the oscillator is operating. When the
ST/SP pin is high, the spindle is activated (operating); when it is low, the spindle stops. When the spindle stops,
the MOSFET at the high side is ON and the MOSFET at the low side is OFF, serving as a short brake.

(2) Torque control
The output stage is driven by applying a differential voltage between the control reference voltage (ECR) and
control input voltage (EC) pins (ECR-EC). With this product, the ECR-EC differential voltage and output PWM
duty have a linear relationship. The input deadband is ±50 mV TYP. and the duty of the standard model is 100%
at 0.75 V (excluding the deadband).
The µPD16882 also has a break selection pin (BRsel). When this pin goes high, ECR is less than EC and the
brake is applied in the reverse direction (refer to the figure and table on the next page).

Reverse torque
If the BRsel pin goes low, a short brake is applied and only the high side is ON if ECR is equal to or less than
EC. When the brake is applied in the reverse direction, the µPD16882 detects the reverse revolution of the
motor and then stops. For ECR-ER and the logic of the BRsel pin, refer to the table below.

Note
Reverse brake
Note The µPD16882 stops after it has detected the reverse revolution of the motor. When the motor revolves
in the reverse direction, the counter electromotive force flows into the VM pin via the channel of the highside Pch MOSFET.
(3) FG pulse selection function
This product can vary index signal (FG) output in proportion to the number of revolutions.
Depending on the setting of the FGsel pin, either single-phase output or three-phase synthesized output can be
selected.
For the logic, refer to the table below.

(4) Standby function
The µPD16882 has a standby function to lower the power consumption when stopped. In the standby status, the
oscillator can be stopped to decrease the circuit current. When STB is made low, the spindle enters the standby
mode, and goes into a high-impedance state.
When the operation mode is restored, it takes the µPD16882 several 10 µs to start up.

NOTES FOR CMOS DEVICES
1
PRECAUTION AGAINST ESD FOR SEMICONDUCTORS
Note:
Strong electric field, when exposed to a MOS device, can cause destruction of the gate oxide and
ultimately degrade the device operation. Steps must be taken to stop generation of static electricity
as much as possible, and quickly dissipate it once, when it has occurred. Environmental control
must be adequate. When it is dry, humidifier should be used. It is recommended to avoid using
insulators that easily build static electricity. Semiconductor devices must be stored and transported
in an anti-static container, static shielding bag or conductive material. All test and measurement
tools including work bench and floor should be grounded. The operator should be grounded using
wrist strap. Semiconductor devices must not be touched with bare hands. Similar precautions need
to be taken for PW boards with semiconductor devices on it.
2
HANDLING OF UNUSED INPUT PINS FOR CMOS
Note:
No connection for CMOS device inputs can be cause of malfunction. If no connection is provided
to the input pins, it is possible that an internal input level may be generated due to noise, etc., hence
causing malfunction. CMOS devices behave differently than Bipolar or NMOS devices. Input levels
of CMOS devices must be fixed high or low by using a pull-up or pull-down circuitry. Each unused
pin should be connected to V DD or GND with a resistor, if it is considered to have a possibility of
being an output pin. All handling related to the unused pins must be judged device by device and
related specifications governing the devices.
3
STATUS BEFORE INITIALIZATION OF MOS DEVICES
Note:
Power-on does not necessarily define initial status of MOS device. Production process of MOS
does not define the initial operation status of the device. Immediately after the power source is
turned ON, the devices with reset function have not yet been initialized. Hence, power-on does
not guarantee out-pin levels, I/O settings or contents of registers. Device is not initialized until the
reset signal is received. Reset operation must be executed immediately after power-on for devices
having reset function.

written consent of NEC. NEC assumes no responsibility for any errors that may appear in this document.
• NEC does not assume any liability for infringement of patents, copyrights or other intellectual property rights of
third parties by or arising from the use of NEC semiconductor products listed in this document or any other
liability arising from the use of such products. No license, express, implied or otherwise, is granted under any
patents, copyrights or other intellectual property rights of NEC or others.
• Descriptions of circuits, software and other related information in this document are provided for illustrative
purposes in semiconductor product operation and application examples. The incorporation of these
circuits, software and information in the design of customer's equipment shall be done under the full
responsibility of customer. NEC assumes no responsibility for any losses incurred by customers or third
parties arising from the use of these circuits, software and information.
• While NEC endeavours to enhance the quality, reliability and safety of NEC semiconductor products, customers
agree and acknowledge that the possibility of defects thereof cannot be eliminated entirely. To minimize
risks of damage to property or injury (including death) to persons arising from defects in NEC
semiconductor products, customers must incorporate sufficient safety measures in their design, such as
redundancy, fire-containment, and anti-failure features.
• NEC semiconductor products are classified into the following three quality grades:
"Standard", "Special" and "Specific". The "Specific" quality grade applies only to semiconductor products
developed based on a customer-designated "quality assurance program" for a specific application. The
recommended applications of a semiconductor product depend on its quality grade, as indicated below.
Customers must check the quality grade of each semiconductor product before using it in a particular
application.
"Standard": Computers, office equipment, communications equipment, test and measurement equipment, audio
and visual equipment, home electronic appliances, machine tools, personal electronic equipment
and industrial robots
"Special": Transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster
systems, anti-crime systems, safety equipment and medical equipment (not specifically designed
for life support)
"Specific": Aircraft, aerospace equipment, submersible repeaters, nuclear reactor control systems, life
support systems and medical equipment for life support, etc.
The quality grade of NEC semiconductor products is "Standard" unless otherwise expressly specified in NEC's
data sheets or data books, etc. If customers wish to use NEC semiconductor products in applications not
intended by NEC, they must contact an NEC sales representative in advance to determine NEC's willingness
to support a given application.
(Note)
(1) "NEC" as used in this statement means NEC Corporation and also includes its majority-owned subsidiaries.
(2) "NEC semiconductor products" means any semiconductor product developed or manufactured by or for
NEC (as defined above).
