LTC4234 reverse current protection

Question

Hi team - 
 
 I am looking for 12V Hot swap solutions with below features . 
 
 Forward current limiting 
 Reverse current block 
 Over voltage protection 
 Over current protection /short circuit protection . 
 Adjustable current limit

I prefer to use integrated MOSFET solution with forward current limiting & reverse current block . 
 
 Please let me know if LTC4233 /LTC4234 support reverse current block feature , It&rsquo;s not clear to me from the datasheet. 
 I would like to know if reverse current block feature is supported only with external MOSFET Solutions .

Inside LTC4233/34, there is one MOSFET. This MOSFET will do forward current limiting. This will not block the reverse current as body diode of the MOSFET will conduct current in reverse direction. You will have to use an ideal diode part (LTC4410,LTC4412,LTC4376) to achieve reverse current blocking functionality. You can also check LTC4368 which can do forward and reverse over current blocking.)
