- Part Number:
- LB1861M-TLM-E
- Manufacturer:
- ON Semiconductor
- Ventron No:
- 3253578-LB1861M-TLM-E
- Description:
- IC BRIDGE DRIVER PAR MFP-14S
- ECAD Model:
-
- Datasheet:

Description
The LB1860 series ICs are drivers 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: Full speed and Low speed. Or, thermistor controlled continuous variable-speed function according to ambient operation temperatures → Motor starts rotating at a low speed.
Motor lock protection and automatic return circuit built in
Output transistors: Output current lo = 1.5 A, output circuit protection Zener diodes (LB1860: M-Vz 57 V/ LB1861: M-Vz=32 V) → Enables low-level noise protection with chip capacitor.
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
Applications
Variable speed fan motor driver
