A family of products, beginning with this Multi Micro Hornet (ORG1510-MK) module combines a MediaTek chip with OriginGPS’ proprietary Noise Free Zone NFZ technology, to create small action sports cameras and wearable devices.
According to OriginGPS, it is the world’s smallest, fully integrated, multi-GNSS (GPS, Glonass and BeiDou) module. The low-power architecture supports an update rate of up to 10Hz and contains onboard flash, making it suitable for use as a GNSS component for devices that require small footprints, such as UAVs designed to follow action sports and other fast-moving activities, or wearable products.
The module contains the MediaTek MT3333 chip, claimed to support the fastest update position calculation rate, as well as an-onboard flash memory that does not erase when power is off. Standby and backup modes ensure it consumes very little power, says the company, and, in advanced applications, a periodic mode can turn the device on and off when in backup or standby.
The module measures just 10 x 10 x 6.1mm yet achieves rapid Time To First Fix of less than one second, accuracy within as little as 1m, and sensitivity at an industry leading -165dBm two constellations simultaneously, claims the company.
The Hornet family of GPS / GNSS antenna modules integrates a GNSS receiver and patch antenna in a single module. The ORG1510-MK is pin-to-pin compatibility with the Micro and Nano Hornet modules ensures a seamless migration from GPS to GNSS. Developers can simply connect the module to a power source on a single layer PCB to begin integrating it into designs.
ICs & Semiconductors
Smallest, lowest power battery management extends lifetime of wearables
Claimed to deliver the industry’s lowest quiescent current, 700nA, and a buck converter, operating at 1.8V, the bq25120 is an integrated battery management IC from Texas Instruments.
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.
