800mA BTL线性控制风扇马达驱动芯片

EUM6883是一款用于单相无刷直流马达的驱动芯片。作为HALL IC和单相直流无刷马达的接口，它通过BTL线性控制输出对马达进行驱动，具有低导通压降、低噪声、高效率的特点。EUM6883内置线性控制模式、风扇转速输出、锁定保护、自动重启以及热关断等功能，并能为Hall IC提供偏置。当输出电压由低到高或由高到低变化时，线性控制模式会根据转速快慢调整其变化斜率，使马达能应用在对静音和可靠性要求较高的电子设备中。如果马达在运转过程中被卡住，过驱动电流会引起温度升高而损坏马达。为防止此现象，马达卡住时EUM6883会切断驱动电流，几秒钟后再尝试恢复驱动。风扇转动时RD为低电平，停转时为高电平。FG • 线性控制，单相全波驱动\n• 宽应用电压1.8V～13.8V\n• 低导通压降（0.5V @ 250mA）\n• FG转速检测输出\n• 锁定检测，自动重启\nRD低电平正常运转，高电平锁定\n• 1.5V Hall偏置\n• 热关断保护\n• MSOP-10封装\n• 符合RoHS规范及Pb-Free;
