New system power-management device manages optimum power for application processor, memory, I/O, camera, audio and LED backlighting

SAN JOSE, Calif. -- Toshiba America Electronic Components, Inc. (TAEC)*, a committed leader that collaborates with technology companies to create breakthrough designs, today announced a new system power management IC (PMIC) designed to help optimize power management functions for a wide range of mobile products. The TC7734FTG PMIC adopts a 130-nanometer analog semiconductor process with very low on-resistance and gate charge characteristics, and integrates various power management blocks within a single device.

Rising demand for mobile products is driving concurrent growth in the market for PMICs, as manufacturers continually seek to reduce their products' power consumption. According to Transparency Market Research, the current compound annual growth rate for the global PMIC market (2013-2019) is currently 6.15 percent. By these statistics, the market will reach $46 billion by 2019. [1

"Our customers often face conflicting challenges in battery-powered products where compact, efficient, and highly reliable power management solutions are needed in a short time-to-market window," said Deepak Mithani, senior director, Mixed-Signal Business Unit, System LSI Group at TAEC. "Toshiba is committed to providing power-management solutions that will help them to achieve these goals."

Power management blocks integrated by the TC7734FTG include power paths, switching charger, four-channel buck converters, three-channel low-dropout (LDO) regulators and two- channel LED backlight drivers. The charger block detects various USB(TM) port conditions and restricts the input current to 500mA, 1000mA or 1500mA, and all charger functions operate automatically without the need for any external control signals and it automatically changes the voltage source between the battery and USB connection as needed.

The IC also features an external thermistor that detects the battery's temperature, helping to prevent overheating while the mobile device is charging. Various thresholds and settings of the charger functions can be programmed by the onboard I2C interface. Individual settings of various output voltage levels, power sequences and many other functions can be programmed via I2C, with user-programmable eFuse to fit various platforms needs.

The TC7734FTG is housed in a compact 7mmx7mm QFN64 package with input voltage ranging from 3.4V to 5.5V. The IC integrates various error detect function, including thermal detect, over current limitation and LED open/short detection, to help ensure proper operation of smartphones, tablets, handheld medical devices, industrial PDAs, barcode readers and portable instruments.


Samples of the TC7734FTG PMIC are available now, with volume manufacturing set to begin in April 2015.
