LB1667 - Two-Phase Unipolar Drive Brushless Motor Drivers

LB1667 Description

Ordering number : EN *4944 Monolithic Digital IC LB1668, 1668M, LB1667, 1667M Two-Phase Unipolar Drive Brushless Motor Drivers Preliminary Overvi.

LB1667 Features

* Output protection Zener diodes with variable breakdown voltages
* When the Z1 and Z2 pins are open: VOLM = 57 V
* When the Z1 and Z2 pins are shorted: VOLM = 32 V
* An external Zener diode can be connected between Z1 and VCC.
* Can support both 12-V and 24-V

LB1667 Applications

* which require large output currents and involve large amounts of heat generated in the IC by dissipating the motor coil switching loss in external Zener diodes. 4. Output protection when the motor is lock (C, RD, and FG pins) This circuit detects motor stopping due to, for example, overloading, and
