Connecting capacitors between the CPL1 and CPL2, CPH1 and CPH2, and BST and GND
pins generate a BST voltage. Use caution to ensure that the voltage difference between
BST and VM is 3.0V or higher, and that the BST voltage does not exceed the absolute
maximum rating of 15V, especially set the BST voltage direct input.
