LB1667 Product details

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 fu.
