TI Introduces Fully-Integrated Load Switch With Low ON Resistance
Texas Instruments Inc. (TI) introduced a fully-integrated load switch with typical ON resistance (rON) of 5.7mΩ at 3.6V, four times lower than the nearest competitor. TI’s TPS22924C integrates at least four parts into one to simplify subsystem load management. The high level of integration in an ultra-small 1.4 x 0.9mm 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.
Key features and benefits of the TPS22924C include: ultra-low ON resistance of 5.7mΩ at 3.6V offers minimum dropout through the pass FET; input voltage range of 0.75 to 3.6V supports portable applications; 2A maximum continuous switch current covers a wide range of currents; and a low shutdown current of <2uA uses minimum power consumption in shutdown mode.
The TPS22924C is available with samples by the end of December, and evaluation modules in 2Q10. The TPS22924C comes in a small-footprint CSP package (1.4 x 0.9mm), and is priced at $0.55 in 1,000-unit quantities.
