Product Details

Description



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 functions built in
• Thermal shutdown function
