Incorporating an algorithm that converts raw measurements like battery voltage, current and temperature in state of charge (%), absolute capacity (mAhr) and time-to-empty, time-to-full (while charging) values, the ModelGauge m5 standalone fuel gauge has been announced by Maxim Integrated.

Tri-mode wireless charger meets three wireless charge standards
At the AirFuel Alliance Members Meeting, Semtech has unveiled what it claims is the industry’s first complete and self-contained tri-mode wireless charging transmitter.
Digital pressure sensor’s ASIC lowers current consumption
A low current consumption model has been added to the HSPPAD series of digital pressure sensors for integration into smartphones, tablets and wearable devices. The HSPPAD042A has been developed in response to the need smartphones, tablets and wearable electronics using different kinds of software and applications which demand higher performance while increasing the power requirement. Sensors need to be not only power-efficient but also more compact given the higher number of parts integrated, says the company.
Magnetic sensor reduces power consumption and processing time
Designed for portable devices, the MMC3630KJ, is a small, BGA package, magnetometer, from Memsic. The magnetometer integrates a monolithic, three-axis AMR sensor and signal conditioning ASIC and is based on the company’s proprietary technology. The BGA package measures 1.2 x 1.2 x 0.5mm. It has a range of ±30G range, and more than five times better noise level compared to other technologies, says the company. With 600Hz magnetic sensing bandwidth, the magnetometer provides better than 10 accuracy in eCompass applications. The design also has drastically lower system level power consumption and processing time, claims the company. There is also a self-degaussing feature, which can eliminate the output drift due to temperature change and residual magnetic from ambient magnetic field. The series also includes an interruption feature, which can be used for motion detection and data acquisition ready notifications to lower system-level power consumption. http://www.memsic.com
