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.
