H Bridge Pin Diagram. 28 pin htssop top view pin functions pin external components io1 description name no. Figure 1 shows the internal block diagram of the dual h bridge.
It is designed to drive inductive loads such as solenoids relays dc motors and bipolar stepper motors as well as other high currenthigh voltage loads. Since each motor has 2 terminals it can control 2 motors 2x24. Using the h bridge sensing pin 20.
Things to consider when choosing an h bridge needed input voltage for motor determines motor speed.
When we move the 10k pot in one direction the dc motor rotates in one direction and when we move the pot to opposite. Battery connect the circuit according to the below schematic diagram for h bridge motor driver. Place the jumpers included with the l298n module over the pairs at module. L293d motor driver module.
