It integrates four high-side outputs, each rated for 1A continuous, with a typical on-resistance of 95 mOhm per channel. ## What the 95 mOhm Rds(on) means on the board At 1A per output, the 95 mOhm typical Rds(on) produces a 95 mV voltage drop and 95 mW of self-heating per channel. The 3:4 input-to-output ratio means three supply inputs (3.3V, 5V, 12V) are distributed across four output channels — one rail is duplicated internally. This matters for BOM planning: the board must route all three supply rails to the switch, even if only two card voltages are used. ## Industrial temperature and fault protection Integrated fault protection includes fixed current limiting and over-temperature shutdown. No external sense resistor or comparator is needed — the switch limits the output current and latches off if the die temperature exceeds the threshold, then auto-retries when the die cools. This reduces the component count around the card slot by two or three passives per channel. The TPS2226ADB (non-Reel variant) shares the same die and package — functionally identical, differing only in the shipping medium. For dual-sourcing, qualify the TPS2226ADB as a drop-in alternate; the PCB footprint and BOM position are unchanged.","metaTitle":"TPS2226ADBR PCMCIA Power Switch, 4 Outputs, 95 mOhm","metaDescription":"TI TPS2226ADBR PCMCIA switch IC, 4 high-side outputs at 1A each, 95 mOhm Rds(on), supports 3.3V/5V/12V loads.

All three rails must be present at the inputs; the 3:4 input-to-output ratio distributes them across four output channels."},{"question":"What is the closest pin-compatible alternative to TPS2226ADBR?","answer":"The TPS2226ADB (non-Reel) is functionally identical and pin-compatible — same die, same 30-SSOP package.
