Fig 4 HISA01-B Typical connection Diagram
7.1 Power supply bypass：
Power supply should have sufficient bypass capacitors to ensure proper operation, otherwise it may be unstable and reduce efficiency, and the output may be oscillated. Vs power supply should connect an at least 1uF ceramic capacitor paralleled with a low value ESR capacitor, , the capacitance should be at least 10uF/A ; for VCC also requires a 0.1uF～0.47uF ceramic capacitors paralleled with a low ESR value of 6.8uF～10uF bypass capacitor, All bypass capacitors should be connected as close as possible to the corresponding power supply root.
7.2 The signal input is isolated from the power output
Input PWM ( Pulse Width Modulation) square wave signal ground and DIR direction control signal ground and 5V power supply common ground GNDI connection；Separate form the GNDo of the 28V motor supply to ensure that the signal input is isolated from the power output and that the output is stable and reliable.
7.3 DIR direction control signal input
DIR direction control signal is TTL level signal，Control the direction of the current between the OutA and OutB of the output，thereby controlling the direction of rotation of the motor. The working status of the motor is shown in the form below.
