Product details

13.3 mOhm Rds(on) — the pass element that stays cool

The TPS22963CYZPT is a single-channel, N-channel high-side load switch from Texas Instruments, built for general-purpose power-domain switching. Its 13.3 mOhm typical on-resistance keeps conduction loss under 120 mW at the 3 A maximum continuous output — no heatsink needed in most board environments. Input supply (Vcc/Vdd) is not required — the switch is self-powered from the load rail.

Slew-rate control and reverse current protection

Slew-rate controlled turn-on limits inrush current into capacitive loads, preventing upstream supply droop that could reset other devices on the same rail. The On/Off interface accepts a non-inverting logic signal to enable the switch.

6-pin DSBGA — small footprint, fine-pitch assembly

The TPS22963CYZPT is supplied in a 6-pin DSBGA (6-XFBGA) package, also designated as 6-DSBGA. The part is surface-mount only.

Frequently asked questions

What is the Rds(on) of TPS22963CYZPT?

The typical Rds(on) is 13.3 mOhm. This is the on-resistance of the N-channel pass FET at room temperature; actual resistance increases with junction temperature per the device's normalised curve.

Does TPS22963CYZPT have reverse current protection?

Yes, reverse current protection is built in. It blocks current flow from output to input when the output voltage exceeds the input, eliminating the need for an external blocking diode.
