The Infineon BTS500701EGAAUMA1 is a single-channel high-side power switch from the PROFET family, built around an N-channel MOSFET with a typical on-resistance of 7 mOhm.
7 mOhm Rds(on) and 14 A — conduction loss and thermal budget
At 14 A, the 7 mOhm typical Rds(on) produces roughly 1.4 W of conduction loss (I²R). That heat must be sunk through the exposed pad of the 12-BSOP package (PG-DSO-12-16) to the PCB copper plane.
Fault protection set — what it covers and what it does not
The BTS500701EGAAUMA1 integrates fixed current limiting, open-load detection, over-temperature shutdown, and over-voltage clamping. The Auto Restart feature means the switch attempts to re-close after a thermal fault once the die cools, which is useful for intermittent overloads like bulb inrush or motor stall. There is no explicit short-circuit protection flag on the output — the current limiting clamps the peak, but the thermal protection handles sustained shorts.
Obsolete — sourcing reality and replacement path
Infineon has marked the BTS500701EGAAUMA1 as Obsolete. The PG-DSO-12-16 package and 1:1 input-to-output ratio narrow the search to single-channel high-side switches with the same thermal pad layout.
