18V PWM 风扇马达驱动芯片

EUM6861是一款单相直流无刷马达驱动芯片，它内置霍尔信号接口，通过PWM模式对风扇转速进行控制。EUM6861非常适用于PC电源风扇和CPU散热风扇中的可控转速马达驱动。\nEUM6861内置功能包括PWM控制模式、最小转速设置、软启动、风扇转速检测、锁定保护、自动重启和霍尔偏置输出。\nPWM模式可通过调节RCTL电压控制芯片输出，使马达转速可调并保持低噪声、低抖动。最小转速由RMIN来设置风扇转动时的最低速度。软启动功能使风扇在启动时由慢到快逐渐加速，且加速时间可通过SS电容外部调节。如果风扇被外部应力或者障碍物卡住，则过驱动电流可能引起温度升高而损坏马达。为了防止此类现象，EUM68 •18V单相全波驱动输出\n•软启动和重启，外部可调\n•PWM控制模式\n•内置Soft Switching\n•锁定保护与自动重启\n•RD输出 (EUM6861)\n•TSSOP-16与TDFN-14封装\n•符合RoHS规范及Pb-Free，Halogen-Free;
