It switches a resistive or inductive load up to 29 A continuous, with the 3 mOhm typical Rds(on) keeping conduction loss under 2.5 W at full current — manageable with the TO-263-7 exposed pad soldered to a copper plane. The 3 mOhm Rds(on) (typical) at 25 °C junction is the headline parametric for this switch. At 29 A load, the voltage drop is under 90 mV — negligible in a 12 V system. The on-resistance doubles at 150 °C junction, so the designer should budget for ~6 mOhm in worst-case thermal conditions, still low enough to avoid a heatsink in most under-hood placements. The switch operates from an 8 V to 18 V load supply, covering the nominal 12 V automotive range with headroom for load-dump transients. The Vcc/Vdd pin is not required — the device is self-powered from the load supply, simplifying the driver interface to a single On/Off logic input. ## Fault protection and qualification The BTS500201TADATMA1 integrates over-temperature, over-voltage, reverse-battery, and short-circuit protection — a full fault suite that eliminates external clamp diodes, TVS, and resettable fuses from the BOM. The BTS500201TADATMA1 is listed as obsolete by Infineon.","metaTitle":"BTS500201TADATMA1 High-Side Power Switch, 3 mOhm, AEC-Q100","metaDescription":"Infineon BTS500201TADATMA1 automotive high-side switch, 3 mOhm Rds(on), 29 A max output, TO-263-7.
