The 9.6 mOhm Rds(on) at 14A and 8V is specified at 25°C junction. The 6W package power limit means continuous 20A is only possible with aggressive thermal management.
No end-of-life notification has been issued.
Maximum gate charge is 6.2 nC at 4.5V gate drive.
Yes, the 25V Vdss rating provides sufficient margin for 12V input rails in a synchronous buck converter. The half-bridge configuration and logic-level gate drive make it a natural fit.
