Circuit Forms Ideal Diode Function


This circuit uses a low power op Amp and a p-channel FET to form a diode function with a very low 0.05 volt voltage drop.  With the selected FET, the circuit can handle up to 2 Amps of current.  Higher currents are possible with a FET with a lower channel resistance. The total current drawn by the circuit during operation is a low 20 microamps.  The maximum voltage is 15v.
