Product details

Gate drive and threshold — what to expect

The CSD25484F4 specifies a maximum threshold voltage of 1.2 V at 250 µA drain current, and the drive voltage range runs from 1.8 V up to 8 V for achieving minimum on-resistance. That 1.8 V minimum drive means this part can be turned on by a 1.8 V logic rail, but the 94 mOhm Rds(on) figure is quoted at 8 V — expect higher resistance at lower gate drives. Gate charge is 1.42 nC at 4.5 V, so switching losses stay low in moderate-frequency applications like load switching or battery disconnect.

Lifecycle and sourcing

The CSD25484F4 carries an Active product status with ROHS3 compliance. No pin-compatible second source is listed in the official record, so the TI FemtoFET™ line is the direct supply path.

Frequently asked questions

What is the on-resistance of CSD25484F4?

The maximum on-resistance is 94 mOhm at 500 mA drain current with 8 V gate drive. At lower gate voltages like 1.8 V or 4.5 V, expect higher Rds(on) — the datasheet curve shows the trade-off.

What is the maximum drain current for CSD25484F4?

Continuous drain current is rated at 2.5 A at 25°C ambient, measured with the device on a standard PCB. Derate this figure as ambient temperature increases above 25°C.

What is the Vgs threshold of CSD25484F4?

The maximum gate threshold voltage is 1.2 V at 250 µA drain current. Typical threshold is lower — the datasheet provides the distribution.
