LB1861M: Two-Phase Half-Wave Variable Speed Fan Motor Driver
The LB1860 series ICs are driver IC for two-phase unipolar drive DC brushless fan motors. They have functions such as driving, lock protection, restart and speed control.
特性- Two-speed mode select function requiring less external component additions: Full speed and Low speed. Or, thermistor-controlled continuous variable-speed function according to ambient operation temperatures.
- Motor lock protection and automatic return circuit built in
- Output transistors: Output current IO = 1.5 A, output circuit protection Zener diodes
- Built-in thermal shutdown circuit
- Built-in rotation detect function (Drive mode: L, Stop mode: H)
- The LB1860 series can be operated from either 12 V or 24 V power supply by changing an external resistor. (Strong protection against power supply surge)
- Connectable direct to a Hall element
