MOSFET Reverse Polarity Protection Circuit
Accidentally connecting a power supply or battery backwards can instantly damage microcontrollers, sensors, motor drivers, and other sensitive components. Fortunately, a simple
Design of Reverse Connection Protection Circuit
When the power supply is correctly connected, the MOS tube conducts and the subsequent circuit can receive power normally. When the power supply is reversed, the MOS tube cuts off, disconnecting to

Power Supply Anti-reverse Connection Circuit Design
If the power supply is reversed, the conduction voltage of the NMOS is greater than 0, the PMOS is cut off, the parasitic diode is reversed, and the circuit is disconnected, thereby forming a
Software and hardware design of microcomputer relay protection
In this paper, a microcomputer protection device based on the TMS320F28335 chip is developed. Considering the anti-interference of field use, detailed hardware and software design is carried out.
Design of power supply anti-reverse connection circuit
When the power supply is reversed, the parasitic diode is reversed, the on-voltage of the MOS is 0, and the NMOS is cut off, thereby protecting the system. In the figure, D5 is a voltage regulator tube to
