Texas Instruments Intros Industry’s Smallest Integrated Load Switch

Texas Instruments Inc. (TI) has launched a new family of integrated load switches with controlled turn-on and quick output discharge to simplify subsystem load management. The TPS229xx family comes in an ultra-small 0.8x0.8mm wafer chip scale package (WCSP) that is ten times smaller than a conventional discrete solution and supports space-constrained applications, such as portable media players, cell phones and portable navigation systems.

The TPS229xx family has the lowest ON resistance to minimize dropout through the switch compared to competing solutions. In addition, the new TI devices have a low operating voltage range from 0.9V to 3.6V, which enables a variety of portable applications where low-voltage specifications are becoming more popular.

Key features include:
• Up to 2-A maximum continuous switch current
• Ultra-low ON resistance
• Low quiescent current: 82nA at 1.8 V
• Low shutdown current: 44nA at 1.8 V
• Ultra-small WCSP package (as small as 0.64mm²)
• Integrated slew-rate control and quick output discharge options

The TPS229xx family is available now in volume production in a WCSP package. The TPS22901 and TPS22902 have 78mΩ ON resistance in a four-terminal package (0.8x0.8mm). The TPS22903 has 66mΩ ON resistance in a four-terminal package (0.8x0.8mm). The TPS22906 has 90mΩ ON resistance in a four-terminal package (0.9x0.9mm). The TPS22921 and TPS22922 have 14mΩ ON resistance in a six-terminal package (1.2x0.8mm).
