L298N是ST公司生产的一种高电压、大电流电机驱动芯片。该芯片采用15脚封装。主要特点是:工作电压高,最高工作电压可达46V;输出电流大,瞬间峰值电流可达3A,持续工作电流为2A;额定功率25W。内含两个H桥的高电压大电流全桥式驱动器,可以用来驱动直流电动机和步进电动机、继电器线圈等感性负载;采用标准逻辑电平信号控制;具有两个使能控制端,在不受输入信号影响的情况下允许或禁止器件工作有一个逻辑电源输入端,使内部逻辑电路部分在低电压下工作;可以外接检测电阻,将变化量反馈给控制电路。使用L298N芯片驱动电机,该芯片可以驱动一台两相步进电机或四相步进电机,也可以驱动两台直流电机。-L298N is produced by ST a high-voltage, high current motor driver chip. The chip uses 15-pin package. Main features are: high voltage, the maximum working voltage up to 46V output current, instantaneous peak current up to 3A, continuous operating current of 2A rated power of 25W. Contains two H-bridge high-voltage high-current full-bridge driver can be used to drive DC motors and stepper motors, relay coils and other inductive load using standard logic level signal control has two enable control terminal, input signal without affecting the case to permit or prohibit the device work a logic supply input, so that part of the internal logic circuits at low voltage work can be an external sense res
