电机驱动

芯片：L298N

1. 手册信息：
   OPERATING SUPPLY VOLTAGE UP TO 46 V；
   TOTAL DC CURRENT UP TO 4 A；
   OVERTEMPERATURE PROTECTION；
   LOGICAL ”0” INPUT VOLTAGE UP TO 1.5 V(HIGHNOISE IMMUNITY，抗高噪声)。
   
   The L298 is an integratedmonolithic circuit.It is a high voltage, high  current dual full-bridge driver designed to accept standard TTL logic levels and drive inductive loads such as relays, solenoids, DC and stepping motors. The emitters of the lower transistors of each bridge are connected together and the corresponding external terminal can be used for the connection of an external sensing resistor.（l298是一个完整的单片电路,这是一个高电压、高电流双路全桥驱动器，被设计为接受标准TTL逻辑电平、驱动电感负载如继电器、螺线圈、直流电机和步进电机。每个桥的射极连接在一起，相应的外部终端可用于连接外部的传感电阻器）。
