LB1668
Overview
The LB1668 Series are 2-phase unipolar drive brushless motor drivers that feature a wide usable voltage range and a minimal number of required external ponents. They also support the formation of motor lock protection and automatic recovery circuits.
Package Dimensions unit: mm 3098B-DIP10S
[LB1668, 1667]
Functions and 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 power supplies by changing an external resistor.
- Hall elements can be connected directly.
- 1.5-A output current output transistors built in
- Built-in rotation detection function that outputs low when driven and high when stopped (LB1668/M)
- FG signal function that sets FG high when IN- is low, and sets FG low when IN- is high (LB1667/M)
- Motor lock protection and automatic recovery...
