Three-phase Brushless Motor Driver

for Polygonal Mirrors

[For LBP, PPC]

BD67929EFV

No.10016EAT05

●Description

BD67929EFV is a 3-phase brushless motor driver for polygon mirror motors of direct PWM drive type built-in PLL ensuring.

As for its basic function, it is a 3-phase 120°energization direct PWM drive type with power supply rated voltage of 36V

and rated output current 2.3A. It is useful for high speed drive. It has the P-MOS and D-MOS on the output block, and the

output ON Resistance is very low 1.35Ω(Typ.). It is very useful for low power consumption. And this IC is high reliability due

to built-in each protection functions (thermal protection, over current protection, restricted protection circuit).

●Features

1) 3-Phase MOS120°energization, direct PWM drive type

2) High output current: 2.5A

3) Low ON resistance DMOS output

4) PLL control circuit

5) Phase lock detection circuit

6) Current limiting circuit

7) 5V regulator output

8) Power-saving function (SS)

9) Short brake function (SB)

10) Built-in logic input pull-up resistor

11) Restricted protection circuit

12) CLK un-input protection circuit

13) CLK input baffler chattering circuit

14) Over current protection circuit (OCP)

15) Thermal shutdown circuit (TSD)

16) Over voltage lock out circuit (OVLO)

17) Under voltage lock out circuit (UVLO)

18) Electrostatic discharge: 8kV (HBM standard)

●Applications

Laser beam printer, PPC, etc.

Technical Note

●Terminal

function

○HWP,

HVP, HUP, HWN, HVN, HUN/Hall signal input terminal

These terminals are the input terminals of the output signals from Hall elements. This has the comparator with hysteresis.

The width of hysteresis voltage is

±12mV(Typ.).

The output of this comparator will be high if the voltage of HxP terminal

is greater than the voltage of HxN terminal by 12mV, and the level will be low if the voltage of HxP terminal is less than

the voltage of HxN terminal by 12mV. For the countermeasures against noise interface with Hall inputs, the connection of

a capacitor with a capacitance of approximately 0.01 - 0.1µF between HxP terminal and HxN terminal.

○PD/Phase

comparison output terminal

This terminal outputs the signal that is the comparison of FG signal and CLK signal.

○EI/Error

amplifier input terminal

This terminal is the input terminal of the error amplifier.

○EO/Error

amplifier output terminal

This terminal is the output terminal of the error amplifier. It is connected to the input terminal of motor torque command

signal inside the IC.

○CLK/Speed

control clock input terminal

This terminal is the CLK signal input terminal to control the speed. This terminal has the 100kΩ resistor which is

pulled-up to the internal regulator. This block detect the falling edge. In case that there is the noise on the CLK signal, it

makes the miscount of the CLK signal. Be sure to design the pattern without the influence of the noise.

○SS/Start/Stop

signal input terminal

This terminal makes the motor start or stop.

This terminal has the 100kΩ resistor which is pulled-up to the internal regulator.

start

stop

When SS=HI, IC becomes stop condition. Stop condition is Free Run or Short Brake that decided by SB terminal.

Moreover, it makes the HB terminal off, and shut down the current to the Hall element. It is very useful to low power

consumption.

○LD/Phase

locked detection output terminal

When the rotation count of the motor is within 10% of the target rotation count, the LD terminal becomes LO.

This terminal is open drain type output, please connect to the external regulator (0½5.5V recommended) through the

resistor. The capability of this terminal is 15mA maximum, please set the voltage of the external regulator and the value of

resistor to be within 15mA.

○OSC/Connection

terminal of capacitor to set PWM oscillating frequency

This terminal is the connection terminal of capacitor to make the triangle waveform that set the PWM frequency.

PWM

= 44µ / C [Hz]

ex.) when C=220pF, f=200〔kHz〕

○CNF/Connection

terminal of capacitor of Current Sense Amp.

This terminal is the connection terminal of capacitor to compensate the phase of CS Amplifier.

○SB/Short

brake signal input terminal

This terminal is the input signal terminal that set output condition when the voltage of SS is HI. This terminal has the

100kΩ resistor which is pulled-up to the internal regulator. When the voltage of SB terminal turns to LO, all low side

MOS FET turns to ON, and it should be short brake condition. It is very useful to reduce the speed quickly.

○BRMODE/PLL

brake setting terminal

This IC has the two kinds of deceleration method. The method is configurable by which terminal to connect with

BRMODE, VREG or GND terminal. This terminal has the 100kΩ resistor which is pulled-up to the internal regulator.
