Arrow and TI Introduce The Industry’s Smallest Integrated Load Switch

Arrow Electronics and Texas Instruments now offer complete standard linear and logic solutions ranging from op amps, LDO regulators, and peripheral drivers, Load Switches to RS-232, RS-422, RS-485, I²C, voltage level translation, and more—all backed by the support of Arrow’s world-class services, solutions, and technical know-how.

TI's TPS229xx family of integrated load switches provides an easy solution to optimize the power consumption in a system by reducing the current leakages. These load switches are specially designed as a solution to the challenges that portable power management designers are facing. They integrate all the main features of a discrete load switch on a single die, providing maximum performance and flexibility to the end-user. Using integrated load switches is an easy way to implement distributed power management architecture and power down applications when they are not being used.

Key Features

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

Key Benefits

• 2-A maximum current ensures applicability for a wide range of subsystems
• Lowest ON resistance allows minimum dropout through the pass switch
• Low quiescent and shutdown currents extend battery life in all modes

Package Information
TPS22901, TPS22902, and TPS22902B are available in a space-saving 4-terminal WCSP with 0.4-mm pitch (YFP). The devices are characterized for operation over the free-air temperature range of –40°C to 85°C.
