290 mOhm on-resistance — the conduction loss number
That 290 mOhm at 11 A is the number to use for worst-case conduction loss in the thermal loop — at 17 A the I²R loss hits about 84 W, which is within the 227 W dissipation limit but leaves little margin for switching losses in a hard-switched topology. The 10 V drive voltage is typical for standard gate-driver ICs; the part also accepts up to ±20 V on the gate for noise margin in noisy environments.
177 nC gate charge — switching-speed budget
Total gate charge is 177 nC at 10 V. That's a moderate Qg for an 800 V, 17 A device — expect a gate-driver capable of sourcing at least 1 A peak to keep switching transitions under 200 ns. The 2320 pF input capacitance at 25 V drain-source confirms the gate-driver output impedance matters; a 10 Ω gate resistor is a typical starting point for ringing control without excessive turn-on delay.
