When wiring a marine hoisting motor, do not construct any motor control circuit on the wrap-around or plug-in prototype board. The use of high-frequency printed circuit wiring is extremely important to prevent pulse jitter. Usually due to excessive noise at the input of the current sense sensor or error amplifier. Therefore, the printed circuit layout should have a small current signal and a high drive output buffer ground plane and should be returned to the power supply input filter capacitor through separate paths. At VCC, Vref and the error amplifier non-inverting input, whether a ceramic capacitor (0.01μF) needs to be connected close to the integrated circuit depends on the circuit layout. However, all high current loops should be as short as possible, and thick copper traces should be used as much as possible to reduce EMI emissions.
