Load switches support controlled turn-on

The TPS229xx family of integrated load switches offers controlled turn-on and quick output discharge to simplify subsystem load management. They are provided in a 0.8 x 0.8–mm wafer chip-scale package that is 10 times smaller than a conventional discrete solution, The switches suit portable media players, cell phones, and portable navigation systems.

The load switches have an on-resistance from 14 to 90 mΩ. The operating voltage range extends from 0.9 to 3.6 V, has a 2-A max continuous switch current, an 82-nA quiescent current at 1.8 V, and a 44-nA shutdown current at 1.8 V. (Ea/1,000: TPS22901, TPS22902, TPS22903, TPS22906, $0.32; TPS22921, $0.42 — available now.)
