ICs & Semiconductors

FPGAs designed for mobile devices from Lattice Semiconductor are available through the distributor, Mouser.

Available in a tiny 1.6 x 1.2 x 0.6mm, 8pin MLPD package, the SC563 is a dual output, low dropout regulator from Semtech.
It provides two regulated outputs for up to 300mA for each output channel and accepts an input supply rail of 2.3 to 5.5V. It provides two fixed, regulated outputs, which eliminate the need for external resistor divider networks. It is ESD hardened to greater than 4kV for robust circuit protection.
It can be used for portable applications, such as wearable electronics, portable video cameras, smartphones and tablets as well as in femtocells, HDTV, set top boxes and networking devices.

Capable of switching between two different power sources, the TCK32xG power multiplexer IC series are for mobile device charging applications.
The three ICs from Toshiba Electronics Europe are the TCK321G, TCK322G and TCK323G. They are designed for the charging circuits of mobile devices that use dual-input power supply systems, consisting of AC adapters, USB or wireless charging inputs, for example, smartphones, tablets and wearable technology.
Power source is selected through the ICs external signal control and a built-in auto selection mode function which switches sources automatically according to priorities that are programmed in advance. Built in protection features are a reverse blocking circuit and thermal shutdown. There is also an integrated over voltage lockout (OVLO) that exhibits OVLO voltages between 12 and 15V for the different devices. All three ICs are contained in a WCSP type package, measuring 1.9 x 1.9mm, with 0.5mm pitch, featuring a maximum output current of 2A and a maximum input voltage of 36V.

A small footprint and up to 4MHz switching frequency enable the AS1382 to be implemented in very small power circuits in mobile phones and wearables, says ams.
