The L298 is an outstanding high-voltage, high-current, dual full-bridge motor driver. It can easily accept standard TTL logic levels and drive various inductive loads like relays, solenoids, DC motors, and stepping motors. It comes in a staggered, 15-lead Multiwatt package. Check below for a breakout board. Key features include an operating supply voltage of up to 46V, a 4.5 - 7VDC logic supply voltage, a total DC current of up to 4A, low saturation voltage, over-temperature protection, and high-noise immunity with a logical ‘0’ input up to 1.5V. The datasheet is also available.
Using this motor driver is quite straightforward. First, connect it to a power supply with an operating voltage of up to 46V and a logic supply voltage between 4.5 - 7VDC. Then, connect your inductive loads such as relays, solenoids, DC motors, or stepping motors. When using, make sure not to exceed the total DC current of 4A to avoid overheating. Also, be aware of the over - temperature protection feature. If the device gets too hot, it will protect itself. For maintenance, keep it in a dry and clean environment. Check the connections regularly to ensure they are secure. And always refer to the datasheet for detailed technical information.
