A self-locking circuit, IN_MOtor_Current_DET is input to MCU, OVC_Protect comes from the sampled voltage, VDD is 5V. After power on, without Q503, the 4, 5, and 6 pins of Q503 pad are all 5V, and the
1. PWM Introduction1. PWM definition: Pulse Width Modulation (PWM) is a digital signal that is most commonly used to control circuits. The signal is set to high (5v or 3.3v) and low (0v) in a predefin
Speaking of level conversion, when writing programs, we actually need an oscilloscope to observe the phenomenon, which means that we pay the tuition for 211 universities, but we are not attending a 21
