P-channel power switch in a 3-PICOSTAR footprint
The CSD25484F4T: With a maximum on-resistance of 94 mOhm at 8 V gate drive and 500 mA load, and a gate charge of just 1.42 nC at 4.5 V, this part switches efficiently from low-voltage logic rails. The wide junction temperature range of -55°C to 150°C suits it for automotive under-hood, industrial, and outdoor telecom environments where thermal cycling is a concern.
Ratings that decide the fit
The 1.42 nC gate charge at 4.5 V keeps switching losses low in high-frequency PWM applications, and the 230 pF input capacitance at 10 V drain-source means the gate driver does not need to source much peak current. The -12 V maximum gate-source rating gives headroom for negative gate-drive spikes in bridge circuits.
