AEC-Q100 dual high-side switch for 12 V automotive loads
The BTS70102EPAXUMA1: It integrates two N-channel MOSFETs with a 9.5 mOhm typical Rds(on), each rated for 6.5 A continuous output, in a single PG-TSDSO-14-22 exposed-pad package. The load supply range spans 6 V to 18 V, accommodating the 12 V automotive bus with margin for cold-crank dips and load-dump transients. The device needs no external Vcc supply — it is self-powered from the load rail.
Fault protection and diagnostic coverage
Built-in fault protection covers current limiting (fixed threshold), open-load detection, over-temperature shutdown, over-voltage clamping, and under-voltage lockout (UVLO). The slew-rate controlled switching reduces EMI coupling into adjacent harness wires.
Package thermal management and board integration
Surface-mount assembly with the exposed pad soldered to a copper plane is essential — without it, the thermal resistance rises and the 6.5 A per channel derates earlier than the datasheet curve predicts.
Sourcing and compliance posture
It is ROHS3 compliant (2011/65/EU + 2015/863). For a dual-channel high-side switch with this Rds(on) and AEC-Q100 grade, the BTS70102EPAXUMA1 is the current-production order code.
