2, the widely used H-bridge driver chip: L928N is favored for its simplicity, low cost and easy procurement. The chip has built-in dual H-bridge circuit, PWM control and current acquisition functions. However, it has two significant problems: First, according to the specification, the drive voltage needs to be 5V higher than the control logic voltage, which is not suitable for single-power supply application scenarios. Secondly, the energy loss in the H-bridge circuit is too large.
