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 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

LB1861M屬于集成電路（IC） > 電機驅(qū)動器，控制器。安森美半導體公司制造生產(chǎn)的LB1861M電機驅(qū)動器，控制器產(chǎn)品屬于電機驅(qū)動器和控制器電源管理集成電路 (PMIC) 系列，可用于控制或操作從某電源施加到電機或相關機電執(zhí)行器的電源。所實現(xiàn)的具體功能和特性集根據(jù)預期負載和預期應用的特性有很大差異，范圍從用于有刷電機的簡單開環(huán)速度控制到基于步進電機的高級閉環(huán)運動控制。
