TI Korea (CEO Kent Chon, www.ti.com/ww/kr ) August 13, 2014 – TI (CEO Kent Chon) announced the launch of a bidirectional 18V, 5A protection switch product that achieves the industry's smallest size and high power efficiency. These compact devices reduce the overall solution size and extend battery life for mobile devices, adapter-powered products, and enterprise and client solid-state drives (SSDs).

As enterprise SSDs require reading and writing larger amounts of data than ever before, they demand faster speeds and greater reliability in increasingly smaller form factors. TI’s TPS25940 and TPS25942 feature back-to-back FETs, enabling bidirectional current control and reducing system size by up to 50% compared to discrete solutions. Additionally, these intelligent eFuse ICs reduce board space by maintaining 2% overvoltage/undervoltage threshold accuracy and eliminating the need for a separate power supply voltage monitoring chip.

The TPS25940 eFuse power switch provides DevSleep mode, which allows the host and device to operate the SSD Serial ATA (SATA) interface in an ultra-low power mode, thereby reducing power consumption to less than 5mW. The TPS25942 eFuse power multiplexer (MUX) product integrates an enable block function, allowing the system to select between non-ideal diode mode and ideal diode mode.

The intelligent eFuse device of the TPS2594x reduces power consumption by providing an active mode and low switch resistance (rated at 42 mW ) along with DevSleep mode, thereby extending battery life and reducing power loss. In addition, it has the advantage of being an intelligent MUX that minimizes bus droop and power stress in the event of a short circuit with a rapid short-circuit response of 200 ns, and can designate two power sources of the same voltage as primary and secondary power sources without turning off the overcurrent protection NFET on either side, thereby reducing the hold-up capacitor requirement by up to 70%.

TI has also released a new Power Management Unit (PMU) product with six built-in buck regulators. These are designed for use with SandForce® SF3700 SSD controllers in laptops and PCs. The LM10692 operates at a 2 MHz switching frequency and provides phase shift functionality, thereby reducing input current ripple. Furthermore, this integrated PMU product minimizes inductor and capacitor sizes, saving valuable board space. Combining TI's LM10692 and MSP430 with SandForce's SF3700 controller reduces the system size to a compact 13.5 mm x 9.3 mm footprint. TI is collaborating with SandForce controllers by joining the SandForce Trusted® program to provide the best support to customers using TI solutions and to help them accelerate time-to-market.
