LM5064: Negative current limiting/current breaker solution for lower current

Part Number: LM5064

Tool/software:

Hello TI Team,

We are searching for the negative current limiting/current breaker solution for the below specification:

Input Voltage: -24VDC

Input current (max): 0.5A

Power(max): 10W

We have found LM5064 for the solution. As per the datasheet page#21 to maintain accuracy, the sense resistor voltage should not be less than 3 mV. But our calculated Vsense voltage comes near 1.5mV. So kindly suggest the better solution.

Also, is there any negative input voltage load switch for the current limiting, which we can use for the current limiting (instead of LM5064). 

Thank you for answer and your time.

Regards,

Parth
