Construct a dedicated power path controller system

Published Time: 2022-08-15 15:53:26
In many cases, our circuits are designed to have two power sources, such as an adapter and a battery, or even two other power sources from two different outlets.
itional pins -- control and state. The control pin can be used to digitally control the input to force the MOSFET to shut down, while the state pin is an open-drain output pin that can be used to absorb 10uA current and can be used to control with external resistance. This can also be interacted with the microcontroller to obtain the presence of an auxiliary power supply signal. The LTC4412 also provides reverse polarity protection for the battery. But since we are using power supply, you can also look at other designs here, such as overvoltage protection, overcurrent protection, reverse polarity protection, short circuit protection, hot swap controller, etc. May come in handy


Another component uses two P-channel MOSFETs to control the auxiliary and main power supplies. For this purpose, the FDC610PZ is used as A P-channel, -30V, -4.9A MOSFET suitable for 3A load switch operation. It has a low RDS ON resistance of 42 milliohm, making it suitable for this application w
