LB1860M: 2-Phase Half-Wave Variable Speed Fan Motor Driver
The LB1860M is driver for two-phase unipolar drive DC brushless fan motors. They have functions such as driving, lock protection, restart and speed control.
Features- Two-speed mode select function requiring less external component additions
- Motor lock protection and automatic return circuit built in
- Output transistors :Output current IO = 1.5 A, output circuit protection Zener diodes (M-Vz = 57 V)
- Built-in thermal shutdown circuit
- Built-in rotation detect function
- 12 V or 24 V power supply by changing an external resistor
- Connectable direct to a Hall element
