15 A continuous current monitor for 2.7 V to 24 V rails
The Texas Instruments TPS259827ONRGET is a current monitor in a 24-VFQFN exposed pad package, rated for a continuous output current of 15 A and an input voltage range of 2.7 V to 24 V.
±5% accuracy and 15 A — what drives the BOM fit
The 15 A continuous output rating sets the maximum load the monitor can pass without entering thermal shutdown — budget the derating for ambient temperature and PCB copper area under the exposed pad. The ±5% accuracy on the current sense output defines the guard band for overcurrent and short-circuit thresholds; a 10 A limit requires a trip point no higher than 9.5 A to stay within the monitor's tolerance. Input voltage spans 2.7 V to 24 V, covering common 3.3 V, 5 V, 12 V, and 24 V rails — one part number for multi-rail designs, but confirm the minimum operating voltage against the downstream load's UVLO.
