High voltage pulses and surges will have energy and attenuation after passing through this reverse-connected diode? What is the principle? Isn't the conduction voltage of the reverse-connected diode v
I would like to ask, the lvd_che_low2dot3V function is used to detect the lithium battery voltage (initial 3V). When it is used to control the motor switch valve in the device, when the detection volt
