The 15 A output rating is the continuous current the internal FET can pass without exceeding the thermal limits of the package when the exposed pad is soldered to a proper PCB copper plane.
For a BOM freeze or a new-design qualification, this part does not carry obsolescence risk.
No. The TPS259823ONRGET has an Active lifecycle status with no NRND or EOL notice. It is suitable for new designs and production builds without LTB risk.
The TPS26621DRCR is a similar electronic fuse from TI but rated for only 0.88 A output and 4.5 V minimum input — it is not a pin-compatible or direct replacement. For the 15 A / 2.7 V to 24 V capability of the TPS259823ONRGET, there is no listed second-source alternate; the part is functionally unique in that current tier.
The current-monitor output accuracy is ±5%. This is the tolerance on the load-current sense signal the part outputs — adequate for system-level power monitoring and fault detection, but not for precision metrology (where a dedicated current-sense amplifier like the INA199B2QDCKRQ1 at 1.5% would be used).
