What the 14 mOhm Rds(on) and 6 A rating mean for your rail
The TPS22958DGNR is a single-channel, high-side load switch from TI with a typical on-resistance of 14 mOhm and a continuous output current rating of 6 A.
Load discharge and slew rate — why they matter on a capacitive bus
The part includes a load-discharge path that pulls the output to ground when the switch is off. The slew-rate-controlled turn-on limits inrush current into bulk capacitance.
Package and thermal — the exposed pad is not optional
Without that thermal path the junction temperature rises above the 105°C operating limit at 6 A continuous. The pad footprint and via pattern under the part are part of the thermal design, not just a mechanical detail.
Lifecycle status is Active — TI is still manufacturing the TPS22958DGNR, so there is no last-time-buy deadline to manage.
