Variable Speed Fan Motor Driver

Overview

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.

Package Dimensions

unit: mm

3098B-DIP10S

[LB1860, 1861]

Features and Functions

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.

鈫?/div>

Motor starts rotating at a low speed.

Motor lock protection and automatic return circuit built in

Output transistors: Output current I

= 1.5 A, output circuit

protection Zener diodes (LB1860: M-Vz = 57 V/ LB1861:

M-Vz = 32 V)

鈫?/div>

Enables low-level noise protection with chip capacitor.

Built-in thermal shutdown circuit

Built-in rotation detect function

(Drive mode: 鈥樷€楲鈥欌€? Stop mode: 鈥樷€楬鈥欌€?

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
