How can we replace the relay in a battery charger by one or two MOSFETs? I imagine a P MOSFET mounted as a polarity protection and directly charging the battery through a schottky, and the voltage of the battery sensed by a BJT thru a voltage divider that will block the MOSFET as the battery reaches 14 volts or so. What would be the values of the components : transistor (N? P?), voltage divider… Can you explain on that?

HI there, 

can share with us at what application you are trying to replace the relay or send us some circuit diagram. 

thanks!
