Product details

Automotive load switch for power-domain control

The Texas Instruments TPS22965TDSGRQ1 is an automotive-qualified single-channel N-channel load switch in an 8-WSON (2x2 mm) package. It provides a high-side on/off interface with slew-rate control and load discharge, rated for continuous output current up to 4 A with a typical on-resistance of 16 mOhm. The part operates across a load voltage range of 2.5 V to 5.5 V and a bias supply (Vcc) from 0.8 V to 5.5 V. Target applications include power-domain isolation for ECUs, ADAS sensor modules, infotainment clusters, and body-control modules where a low-dropout, high-side switch with controlled turn-on is required.

Temperature grade and qualification for automotive use

Capable is not qualified — this part carries the AEC-Q grade on its series designation.

Supplied in an 8-WSON (2x2 mm) exposed-pad package, the part is surface-mount only.

It is RoHS3 compliant and sold through independent distribution.

Frequently asked questions

Is TPS22965TDSGRQ1 compatible with 5V supply?

Yes. The load voltage range is 2.5 V to 5.5 V, and the bias supply (Vcc) range is 0.8 V to 5.5 V. Both 3.3 V and 5 V rails are within specification, and the on/off input is compatible with 3.3 V and 5 V logic without level translation.

What is the difference between TPS22965TDSGRQ1 and TPS22965DSGRQ1?

The TPS22965TDSGRQ1 is the automotive AEC-Q100 qualified variant. The DSGRQ1 suffix (without the 'T') typically indicates the non-automotive commercial/industrial version. The TDSGRQ1 carries the full automotive PPAP documentation package. Check the specific datasheet for any parametric differences; the base electrical characteristics are expected to be the same.

What is the replacement for TPS22965TDSGRQ1 if obsolete?

The part is currently active with no replacement announced. Should obsolescence occur, the base product number TPS22965 family includes other variants that may be pin-compatible, but no official successor is listed at this time.

How to test TPS22965TDSGRQ1 functionality?

Functional testing requires applying a valid load voltage (2.5 V to 5.5 V) and bias supply (0.8 V to 5.5 V), then toggling the on/off input between logic low and high. With the switch enabled, verify output voltage within drop of Vin (Iload × Rds(on)), and confirm the load discharge feature pulls the output low when disabled. No-load testing is acceptable for go/no-go verification.
