TI Unveils Latest Fully-Integrated Load Switch

Texas Instruments (TI) introduced a fully-integrated load switch with typical ON resistance (rON) of 5.7-mOhms at 3.6-V, which the company stated is four times lower than the nearest competitor.

TI reported that its TPS22924C integrates at least four parts into one to simplify subsystem load management. The high level of integration in an ultra-small 1.4-mm x 0.9-mm chip scale package (CSP) addresses space-constrained, battery-powered applications such as portable industrial and medical equipment, media players, point-of-sale terminals, global positioning systems (GPSs), netbooks/notebooks, and Smartphones.

TI noted that key features and benefits of the TPS22924C include:

- Ultra-low ON resistance of 5.7-mOhms at 3.6-V offers minimum dropout through the pass FET

- Input voltage range of 0.75 V to 3.6 V supports portable applications

- 2-A maximum continuous switch current covers a wide range of currents

- Low shutdown current of <2uA uses minimum power consumption in shutdown mode

- The TPS22924C is the newest member of TI's extensive load switch family. The new switch complements TI's portfolio targeting the portable equipment market, which includes battery chargers, DC/DC converters and OMAP processors
