BQ2970: Small capacity battery for protection

Part Number: BQ2970
Other Parts Discussed in Thread: BQ2980

HI Team,

My customer has one battery with 120mAh, and the max discharging is only 2C, so we need to limit the discharging current within 0.5A.

then we select bq29700 shown below spec, the OCD is 100mV, which means we need to pick up a FET with on-resistance up to 0.2ohm to meet this small discharging current. correct?

if correct, it is hard to find a suitable FET (25V/200mohm). or do you have any recommendation? 

Or do we have small OCD threshold part?
