The L298P013TR can handle a maximum current of 2A per channel, with a peak current of 3A for a short duration (less than 20ms).
To protect the L298P013TR from back-EMF, you can add a freewheeling diode (also known as a flyback diode) in parallel with the inductive load. This diode allows the current to continue flowing when the switch is turned off, preventing the back-EMF from damaging the IC.
The enable pins (EN1 and EN2) are used to enable or disable the corresponding bridge drivers. When the enable pin is high, the bridge driver is enabled, and when it is low, the bridge driver is disabled. This allows you to control the motor or load independently.
The sense resistor value depends on the maximum current you expect to flow through the motor or load. A general rule of thumb is to choose a sense resistor value that limits the current to 1.5 to 2 times the maximum expected current. You can use the formula Rsense = 0.5V / Imax to calculate the sense resistor value, where Imax is the maximum expected current.
The VCC pin is the power supply pin for the logic circuitry, and the VSS pin is the ground pin for the logic circuitry. The VCC pin should be connected to a stable 5V power supply, and the VSS pin should be connected to the system ground.
