Hi Team,
My customer considers to design an ideal diode with OPAMP + Pch MOSFET as the following.
http://www.edn.com/design/analog/4368525/Use-a-self-powered-op-amp-to-create-a-low-leakage-rectifier
I would like to suggest TI OPAMPs, is there any application note for this requirement?
My customer's requirement is the following and I believe OPA197 and OPA191 is applicable.
---------------------------------------
1) Vin=4~25V
2) reverse leakage current: less than 1mA
3) maximum reverse voltage: more than 28V
4) on resistance: less than 30mΩ
*I think 2) and 4) are requirements for Pch MOSFET.
---------------------------------------
May I have your comments?
