Its 22 mOhm typical on-resistance keeps conduction loss under 0.11 W at 2.2 A continuous — a meaningful margin for the 8-SON exposed-pad thermal path. Rated for a load voltage range of 2.5 V to 6.5 V, it covers 3.3 V and 5 V automotive logic and sensor rails without needing an external Vcc supply. ## Sizing the current limit and fault protection The adjustable current limit lets the designer set the threshold between the load's normal peak and the short-circuit ceiling — useful when the same switch must handle multiple ECU variants with different harness capacitances. Over-temperature shutdown and undervoltage lockout (UVLO) are integrated; the status flag output signals a fault to the system controller without a separate comparator. ## Active production — sourcing posture for the BOM line Supplied in Tape & Reel (TR) or Cut Tape (CT) on an 8-VDFN exposed-pad package (8-SON 3x3 mm). The ROHS3 compliance eliminates the need for a lead-free process waiver.","metaTitle":"TPS2557QDRBTQ1 Automotive Power Switch","metaDescription":"Texas Instruments TPS2557QDRBTQ1 automotive-grade high-side power switch. 5A max output, 22mOhm Rds(on), AEC-Q100 qualified.
