Claimed to be the industry’s lowest power, smallest footprint Bluetooth Smart solution, the Atmel SmartConnect Bluetooth Smart BTLC1000 consumes less than 4mA in RX and less than 3mA TX at 3.6V. According to the company, it can increases battery life by as much as one year or more for certain applications.
The 2.2 x 2.1mm WLCSP is ‘unparalleled’ says the company and significantly smaller than alternatives available on the market today. The tiny, low-power SoC opens up possibilities for IoT and wearable markets, says the company, enabling applications such as fitness trackers and medical devices, along with human Interface devices, asset trackers and beacons.
Wearable
Motion sensor creates implantable applications
Designed for medical applications, including implantable devices classified by US Food and Drug Administration as Class III, the MISDH is a low power, three-axis accelerometer from STMicroelectronics.
It measures just 2.0 x 2.0 x 1mm³ and consumes down to 2µA in low power mode. As well as 8-, 10- and 12bit operating modes, ±2g/±4g/±8g/±16g are selectable. Output data rate is 1Hz to 5kHz and operating voltage is 1.71 to 3.6V.
Sensor hub IC includes Bluetooth v4.1
Designed for wearable products, the TZ1041MBG is an application processor that has been added to Toshiba Electronics Europe’s ApP LiteM TZ1000 family.
Buck regulator delivers industry’s highest power conversion efficiency
Able to extend battery life in portable devices by virtue of what is claimed to be the industry’s highest light-load power conversion efficiency at 90%, the ADP5301 buck regulator consumes just 180nA quiescent current.
It is, says Analog Devices, designed to deliver maximum power for a longer period of time than previously achievable and is suited for IoTapplications, including wireless sensor networks and wearable devices such as fitness bands and smartwatches.
It is housed in a tiny WLCSP package that measures less than 3.1mm².
The input voltage is from 6.5 to 2.05V to enable a range of battery sources or architectures. Selectable, low-noise forced PWM mode, with low output voltage ripple powers noise-sensitive analogue load up to 500mA output current.
The ADP5301 and ADP5303 (with VOUT OK and VIN OK flags, respectively) are offered in a nine-ball WLCSP, and the ADP5300 and ADP5302 (VOUT OK and VIN OK flags, respectively) are available in a 10-lead LFCSP.
