Product Overview
TPS22965 is a Texas Instruments single-channel load switch for Power_Management designs that need controlled switching of low-voltage rails. The device uses a separate bias supply from 2.5 V to 5.7 V and accepts VIN from 0.8 V to 5.7 V, with the recommended condition that VIN must be less than or equal to VBIAS.
The switch is rated for 6 A maximum continuous switch current, with an 8 A pulsed switch-current limit for pulses below 300 us at 2% duty cycle. ON control is active high for TPS22965 and TPS22965N. The TPS22965 version includes quick output discharge, while TPS22965N does not.
The device is offered in an 8-pin WSON/SON (DSG), 2.00 mm x 2.00 mm package with a thermal pad. Recommended use includes a 1 uF input capacitor, operation across -40°C to +105°C free-air temperature, and thermal design using the listed 72.3°C/W junction-to-ambient and 13.2°C/W junction-to-case-bottom thermal resistances.

Procurement Notes
When requesting a quote for TPS22965, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.
If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.
For power IC and power device sourcing, voltage rating, current rating, power dissipation, package thermal performance, protection features, qualification grade and application conditions should be reviewed before approval.
FAQ
What input voltage range does TPS22965 support?
TPS22965 supports a recommended VIN range from 0.8 V to 5.7 V. The extracted operating condition states that VIN must be less than or equal to VBIAS, with VBIAS specified from 2.5 V to 5.7 V.
What switch current ratings are specified for TPS22965?
The extracted absolute maximum ratings list 6 A maximum continuous switch current. A maximum pulsed switch current of 8 A is also specified when the pulse is under 300 us at a 2% duty cycle.
Does TPS22965 include quick output discharge?
Yes. The extracted facts state that quick output discharge is present for TPS22965 only. The related TPS22965N condition states quick output discharge is not included for TPS22965N.
What package is used for TPS22965?
TPS22965 is listed in an 8-pin WSON/SON (DSG) package measuring 2.00 mm x 2.00 mm with a thermal pad. The extracted thermal data also applies to the DSG WSON 8-pin package.
