LB1860M

Ordering number: EN3519A Monolithic Digital IC LB1860,1860M,1861,1861M 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. → Motor starts rotating at a low speed. Motor lock protection and automatic return circuit built in Output transistors: Output current IO = 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 SANYO : DIP10S unit: mm 3111-MFP14S [LB1860M, 1861M] SANYO : MFP14S SANYO Electric Co.,Ltd.
