Motor Drivers for Printers Three-phase Brushless Motor Driver for Polygonal Mirrors For LBP, PPC No.10016EAT05 BD67929EFV 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 120energization 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 1.35(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 MOS120energization, 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. www.rohm.com 2010.12 - Rev.A 1/14 2010 ROHM Co., Ltd.
