It integrates four independent power switches, a serial interface for control, and a status flag output for fault reporting, all in a 30-SSOP package. Typical applications include PCMCIA/CardBus slots in notebook PCs, industrial handheld terminals, and docking stations where the host needs to sequence and protect each card's VCC and VPP rails. With a typical on-resistance of 95 mOhm per channel, the conduction loss at 1 A is just 95 mW per output. Under full load on all four channels, the total I²R dissipation is about 380 mW — well within the thermal capability of the SSOP package on a standard PCB without forced airflow. The fixed current limit (typically around 1.2 A to 1.5 A) and over-temperature shutdown protect the switch and the load if a card draws more than the 1 A rating. ## Industrial temperature grade and protection A buyer can commit the BOM line without near-term obsolescence risk.","metaTitle":"TPS2226ADBG4 PCMCIA Switch, 4-Ch 1A, 95mOhm, Active","metaDescription":"Texas Instruments TPS2226ADBG4 PCMCIA power switch, 4 outputs at 1A each, 95mOhm Rds(on), 3.3V/5V/12V load, -40°C to 85°C, 30-SSOP.
