Part Number:LM5060-Q1
Hello,
I need a reverse battery protection for a CC/CV (buck) charger (14.5V / 1Amp). I'm thinking of LM5060 (generic application diagram; Vin - charger output, Vout - battery port). I do not need a back-to-back switch as the input polarity is guaranteed (charger output). In fact, a back-to-back switch would be useful for reverse current flow (from battery to the charger) protection that I need, but LM5060 does not support that functionality, does it ?
In the datasheet, page 4, note (5) refers to -25V maximum. Is adding Ro resistor in series with OUT pin sufficient to protect the device ?
I assume that connecting reverse battery to an unpowered unit should be safe. How about connecting reverse battery to a unit which is up and running (with no or light load), providing 14.5V at the battery port ?
Thank you for your attention.
Regards,
Robert
