productroundup Silicon/software for USB Type-C to DisplayPort cables Cypress Semiconductor has assembled a complete silicon and software offering for USB Type-C to DisplayPort adapters (dongles). The EZ-PD CCG1-based Type-C to DisplayPort Cable solution enables connectivity between a USB Type-C receptacle and a DisplayPort (DP) or Mini DisplayPort (mDP) receptacle, allowing emerging Type-C notebooks and monitors to be interoperable with older products. Cypress has demonstrated that its Type-C to DP solution is interoperable with the Apple MacBook, the Google Chromebook Pixel, and multiple other systems. Audio DSP chip will produce a better listening experience, says ON ON Semiconductor and AfterMaster Audio Labs have designed the BelaSigna 300 AM IC that embeds AfterMaster technology, from AfterMaster HD Audio Labs (Hollywood, California) that according to the two companies, will enhance the digital audio listening experience on any consumer device. The chip will operate at 4 mA from a 1.8V source while running AfterMaster HD’s algorithms to offer highfidelity, studio-quality sound to audio-enabled devices and services, using real-time mastering and re-mastering processing technology as well as proprietary Adaptive Intuitive Response mechanisms Complete article, here 20A hot-swap controller has MOSFET & current sense LTC4234 is a 20A Hot Swap controller with integrated MOSFET and current sensing, providing a small footprint hot-plug solution for high density circuit boards. The device ensures safe board insertion and removal from live 2.9V to 15V backplanes by controlling an internal N-channel power MOSFET to gently power up bulk capacitors, avoiding sparks, connector damage and system glitches. By integrating the two most critical and largest Hot Swap components – the power MOSFET and sense resistor – the LTC4234 reduces design time and saves board area. Complete article, here Power-monitoring IC for single-phase AC Microchip Technology’s MCP39F511 is a highly integrated and accurate single-phase power-monitoring IC, designed for the real-time measurement of AC power, combining the most popular power calculations with advanced features. Allowing for more accurate power measurements, this device is capable of 0.1 % error across a wide 4000:1 dynamic range. Its 512 bytes of EEPROM allow operating condition storage. The MCP39F511 also includes two 24-bit delta-sigma ADCs with 94.5 dB of SINAD performance, a 16-bit calculation engine, and a flexible two-wire interface.
