Obsolete — sourcing strategy for BOM continuity
The BTS500601EGAAUMA1 is listed as Obsolete by Infineon.
6 mOhm Rds(on) — thermal budget for 15A loads
The 6 mOhm typical on-resistance is the dominant parameter for power dissipation in this high-side switch. At 15A maximum continuous output, conduction loss is I²R = 1.35W at the nominal Rds(on).
Integrated fault protections — fewer external components
The BTS500601EGAAUMA1 integrates current limiting (fixed threshold), open load detection, over-temperature shutdown, and over-voltage clamping. These protections eliminate the need for external sense resistors, comparators, or clamp diodes in typical 12V automotive loads such as relays, solenoids, lamps, and DC motors. The single-channel high-side configuration with a 1:1 input-to-output ratio and simple On/Off interface means a logic-level GPIO from an MCU or ECU directly controls the load without a separate gate driver.
Package and thermal management checklist
The load voltage range is 9V to 16V, matching a nominal 12V automotive battery bus with cold-crank and load-dump transients. No external Vcc supply is required — the switch is self-biased from the load supply rail.
