Product details

P-channel load switch in a tiny footprint

On-resistance is 205 mOhm maximum at 500 mA with 8 V gate drive, and the gate charge is just 0.96 nC at 4.5 V. That low gate charge means a microcontroller GPIO can switch it directly — no extra driver stage needed — which saves board space and BOM cost. The drive voltage range (1.8 V to 4.5 V for minimum Rds(on)) also makes it compatible with 1.8 V logic families common in low-power designs.

That makes it safe to qualify into a new design without worrying about a last-time-buy window.

Frequently asked questions

Can CSD25483F4T be used for load switching?

Yes, the CSD25483F4T is well suited for low-side or high-side load switching in battery-powered and portable applications. Its 20 V drain rating covers common 3.3 V, 5 V, and 12 V rails, and the low gate charge allows direct drive from a microcontroller GPIO. Keep the continuous load current under 1.6 A and respect the 500 mW power dissipation limit for reliable operation.

Is CSD25483F4T RoHS compliant?

Yes, the CSD25483F4T is ROHS3 compliant, meeting the latest EU restrictions on hazardous substances in electronic equipment.
