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. |
