BQ2970: Li-pol protection circuit

Part Number:BQ2970

Hello!

I'm designing one cell Li-pol protection circuit based on BQ29707 IC. The schematic is similar to the datasheet example:

I need to limit currents of approximately 500 mA. So I've chosen CSD17381F4 FETs. This FET has Rdson=95 mOhm at Vgs = 3.5 V and T = 25°C. So in this case we have:

I = (90 mV) / (2 * 95 mOhm) = 473 mA.

Is this calculation correct? And are CSD17381F4 FETs a good choice for battery protection circuit?

Thank you in advance!
