l293d motor driver power supply

I am confused because I read that the L293D can cause currents up to 600 mA but the max current for an Arduino Uno pin is only 50mA. Thus we insert motor driver in between motor and microcontroller. pinMode(I4, OUTPUT); Where do people get this 50mA number from? Motor driver take the input signals from microcontroller and generate corresponding output for motor. They are rated for 3 to 9V. When an enable input is high, the associated driver gets enabled. My Arduino can accept 7V to 12V DC input and the L293D between 4.5v to 36V. +5V. It means if you want to operate a motor at 9V then you need to provide a Supply of 9V across VSS Motor supply.The maximum voltage for VSS motor supply is 36V. int motorPin3 = 11; Can I Why is that? 9V PP3 batteries have only about 150mAh. digitalWrite(motorPin2, HIGH); No reward points for this product. digitalWrite(motorPin2, LOW); L293 and L293D are characterized for operation from 0°C to 70°C. int motorPin1 = 9;int motorPin2 = 10; analogWrite(E2, 255); // Run in full speed What is the precise legal meaning of "electors" being "appointed"?
