MAX17055 ModelGauge shortens portable device development time

Mon, Apr 03, 2017

MAX17055 ModelGauge shortens portable device development time: Maxim Integrated has released the MAX17055 ModelGauge m5 to speed time to market of portable devices, by eliminating need for battery characterisation, during development.

Developers of portable devices now have an easier way to design in the most accurate and low power host-side battery gauges, says Maxim Integrated, of the MAX17055 ModelGauge m5. Traditionally, fuel gauges require extensive characterisation of each battery type, used in specific applications, to attain good performance. The customer would have to perform complicated battery characterisation, a process which could add weeks to the design cycle. The ModelGauge m5 EZ configuration of the MAX17055, battery characterisation requirement is eliminated, shortening time to market.

MAX20310 PMIC halves form factor for wearables

Fri, Mar 31, 2017

MAX20310 PMIC halves form factor for wearables: Wearable medical and fitness applications can be reduced in size by 50 per cent, says Maxim Integrated. The MAX20310 PMIC supports a low input voltage of 0.7V to provide wearable power management integrated circuits (PMICs) for primary cell architectures.

The MAX20310 low quiescent current (IQ) PMIC supports a low input voltage of 0.7V for the new generation of high-energy density battery architectures such as zinc air and silver oxide, as well as the more commonly used alkaline battery architecture. Personal and remote monitoring gaining traction also benefit from a reduced size and an extended battery life.

Kionix’s three-axis KXTJ3 accelerometer is small enough for key fobs

Fri, Mar 31, 2017

Kionix’s three-axis KXTJ3 accelerometer is small enough for key fobs: Kionix, a Rohm Group Company, announces the release of the KXTJ3, a thee-axis accelerometer. It is packaged in a tiny 2.0 x 2.0 x 0.9mm form factor.  

It follows the Kionix KXTJ2 accelerometer, but offers a size and price point that is embedded in toys, wearables, remote controls to the SmartHome and internet of things (IoT).

STSPIN250 brushed DC motor driver meets portable, battery-powered IoT devices

Tue, Mar 21, 2017

STSPIN250 brushed DC motor driver meets portable, battery-powered IoT devices: STMicroelectronics has announced the STSPIN250 single-chip 2.6A driver for brushed DC motors. The STSPIN250 extends STMicroelectronics’ family of miniature, low-voltage, energy-efficient drivers for battery-powered portable and wearable applications.

 The STSPIN250 driver integrates a full power-MOSFET bridge and fixed off-time PWM current controller in a tiny 3.0 x 3.0mm package that saves space in portable equipment. The low on-resistance of the power stage (200mOhm total, high-side + low-side) and what STMicroelectronics claims is the best-in-the market current-sipping standby mode — below 80nA – to help maximise battery runtime and keep equipment-case temperatures down. Its supply-voltage range of 10 to 1.8V allows designers to specify a power source as small as a single Li-Ion cell.
