The slew-rate controlled turn-on and a status flag output give the system controller visibility into the switch state and fault conditions. Housed in an 8-VDFN exposed pad package (8-SON, 3x3 mm), the TPS2557DRBR dissipates heat through the PCB copper pour under the pad.","metaTitle":"TPS2557DRBR Power Distribution Switch, 5A, 22mOhm, Active","metaDescription":"Texas Instruments TPS2557DRBR high-side power switch, 5A max output, 22mOhm Rds(on), adjustable current limit, -40 to 125°C.
