AEC-Q100 high-side switch for automotive power distribution
The TPS2559QWDRCTQ1: The output is an N-channel MOSFET with a 1:1 input-to-output ratio, controlled by a non-inverting On/Off interface. The part integrates adjustable current limiting, over-temperature protection, reverse-current blocking, and under-voltage lockout — the full set of fault protections expected on an automotive power rail.
13 mOhm Rds(on) and the thermal budget
At 5.5 A, the 13 mOhm typical on-resistance produces about 0.39 W of I²R loss.
