Its 78 mOhm typical Rds(on) means at 500 mA continuous output the voltage drop across the switch is about 39 mV — well under 5 % of a 1 V rail. The load voltage range spans 1 V to 3.6 V, covering core supplies (1.2 V), memory (1.8 V), and I/O (2.5 V, 3.3 V) without a separate level translator. ## Load discharge and slew-rate control — sequenced power-down Integrated load discharge pulls the output to ground when the switch is turned off, preventing floating outputs during power-down sequencing — important for mixed-voltage systems where an unpowered rail can back-feed through ESD diodes. Slew-rate control limits inrush current into capacitive loads, reducing supply droop on the input rail during turn-on. The switch is controlled by a single On/Off input with non-inverting logic. ## 4-DSBGA package — footprint and rework The device is housed in a 4-bump DSBGA package — a 0.5 mm pitch fine-pitch BGA. Surface-mount assembly requires a solder-paste stencil with aperture matching the bump diameter, and rework demands a hot-air station with a nozzle sized for the 4-bump array.","metaTitle":"TPS22902BYFPR Load Switch, 78 mOhm, 1-3.6 V, 500 mA, Active","metaDescription":"Texas Instruments TPS22902BYFPR general-purpose load switch. 78 mOhm Rds(on), 500 mA max output, 1 V to 3.6 V load range.

Typical applications include power-gating of peripheral blocks, sequenced power-up of sub-circuits, and inrush-current limiting for capacitive loads. The 1 V to 3.6 V load range covers core, memory, and I/O rails in battery-powered and low-voltage designs."},{"question":"Is the TPS22902BYFPR obsolete or nearing end of life?","answer":"No. The product status is listed as active. There is no indication of phase-out or last-time-buy.
