Three-phase Brushless Motor Driver with Speed Control - BD67929EFV

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 1.35O(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).

* This product is a STANDARD grade product and not recommend for on-vehicle devices.
