Product details

The TPS259631DDAT is an electronic fuse from Texas Instruments that accepts a 2.7 V to 19 V input rail.

Electronic fuse vs. polyfuse — active current limiting

Unlike a resettable PTC that relies on self-heating, this electronic fuse actively limits the output current to 2 A with ±10.4% accuracy.

Package and thermal — the PowerPad is non-negotiable

Without that thermal path, the 2 A rating cannot be sustained at the upper end of the temperature range. Surface-mount assembly — standard reflow profile for the SOIC footprint.
