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.
