TLV9002-Q1: bi-directional OC detection

Tool/software:

Hi, 

              My customer is designing a 48V auto BMS system. orignial, they are evaluting TPS4800 + INA solution to meet bi-directional  low side OC detection, but due to cost  sensitive, so, would like to check if low cost Q-grade Amplifers could do this, do you have PN and design recommendation? BTW, the output of OC signal need to directly control TPS4800 to open and close contactor. thanks.
