Dual 4 A load switch for automotive power distribution
The TPS22968NQDMGRQ1: The 1:1 input-to-output ratio means each of the two outputs is independently gated by the On/Off interface, making this part a two-channel power-distribution switch in a single 10-WSON (3x2) package. That temperature grade, combined with the qualification, places it in under-hood and engine-bay power-distribution roles — not just cabin electronics.
29 mOhm Rds(on) — sizing the conduction loss budget
At 4 A per channel, the I²R conduction loss is 0.46 W per channel. The slew-rate controlled turn-on limits inrush current into capacitive loads. For a 4 A switch driving a capacitive load, the controlled ramp prevents the input supply from dipping below the undervoltage lockout threshold of the preceding regulator.
Active lifecycle — no end-of-life planning needed
For a production program, this part does not introduce obsolescence risk at the BOM level. The same base part in a non-automotive grade or different package would carry a different suffix — confirm the full order code matches the BOM line.
