Mouser offers explorer kit to evaluate u-blox location hardware and software

Thu, Sep 30, 2021

To evaluate the potential of Bluetooth 5.1 direction finding and high precision indoor positioning for access control, collision detection, smart home appliances and asset tracking, the u-blox XPLR-AOA-1 Explorer Kit for Bluetooth Direction Finding is available from Mouser.

The u-blox XPLR-AOA-1 Explorer Kit contains an antenna board with a u-blox NINA-B411 Bluetooth Low Energy module, transmitter tag with NINA-B406 Bluetooth Low Energy module and u-connectLocate direction finding software. The software runs directly on the NINA-B411 module’s embedded Nordic Semiconductor nRF52833 SoC, calculating the angle of arrival (AoA) of the incoming signals with no additional processing required.

Engineers can combine several XPLR-AOA-1 kits and triangulate directions from three or more antenna boards to create a full positioning system. Target applications include detecting whether a person or an object is approaching a door, avoiding collisions between moving objects, and directing a camera at a moving tag.
Mouser claims to offer the world’s widest selection of the newest semiconductors and electronic components — in stock and ready to ship.

To help speed customers’ designs, Mouser’s website hosts an extensive library of technical resources, including a Technical Resource Centre, along with product data sheets, supplier-specific reference designs, application notes, technical design information, engineering tools and other helpful information.

Digi-Key Electronics continues support for Winning Combinations

Tue, Sep 14, 2021

Following the acquisition of Dialog by Renesas, distributor Digi-Key Electronics has confirmed that it will continue to support the product portfolios of both companies.

Digi-Key has announced five new product combinations from Renesas and Dialog, following the announcement. They are a 100W adapter with power delivery (PD) and wireless charger, a smart asset tracking label, a smart connected pulse oximeter, a smart time-of-flight (ToF) -based range finder with mobile app and a smart lock with low power Wi-Fi and Bluetooth Low Energy.

These expert designs showcase both Renesas’ and Dialog’s complementary, and now combined, product portfolios for embedded processing, analogue, power and connectivity. Winning Combinations are engineering-vetted designs which can be used by customers. They are encouraged to take advantage of an elevated platform for their own design ideas in order to accelerate the product development cycle and lower the overall risk to bring a design to market.

“We are proud to support the completion of the merger between Renesas and Dialog by offering new winning combinations from their extensive product portfolio,” said David Stein, vice president of global supplier management for Digi-Key.

Digi-Key Electronics is headquartered in Thief River Falls, Minnesota, USA. It describes itself as a leader and continuous innovator in the high service distribution of electronic components and automation products worldwide.

Digi-Key provides more than 11.7 million components from over 1,900 quality name-brand manufacturers with an industry-leading breadth and depth of product in stock and available for immediate shipment.

Digi-Key also supports design engineers and procurement professionals with a wealth of digital solutions and tools to make their jobs more efficient.

Farnell extends Nordic Semiconductor offering with its first PMIC

Fri, Aug 20, 2021

The first power management IC (PMIC) from Nordic Semiconductor, the nPM1100, is now available from Farnell. Claimed to be the industry’s most compact PMIC, it is intended for wearable electronics, remote controls, personal medical devices and smart home sensors.

The nPM1100 can be used as a generic PMIC for any application using rechargeable Li-ion/Li-Po batteries, advised Farnell. PCB space requirements are as low as 23mm², makes it particularly well suited to be integrated into wearables, connected medical devices and projects which have limited space. No configuration software is required to operate as all settings are pin-configurable. It can be used to conserve energy in designs, and can charge small batteries while providing efficient power management in

The nPM1100-CAAA is a small form factor dedicated PMIC with a dual-mode configurable buck regulator and integrated battery charger. It is a complementary component to Nordic’s SoCs and also has over-voltage protection, low current mode and an operating range of -40 to +85 degrees C.

Farnell also offers the nPM1100 evaluation kit which does not require software to operate and is performance optimised for the PMIC with electrical connectors and physical interfaces for operation. It features switches for all selectable settings, buttons to enter and exit ship mode and connectors for batteries, USB and headers for all pins on the PMIC. The kit may be used with other development kits such as Nordic’s nRF5340-DK or it can be used to test the PMIC’s functionality with non-Nordic products. The kit also includes indicator LEDs for charge and error indication.

Nordic Semiconductor specialises in low power wireless technology with Bluetooth Low Energy solutions, complemented by ANT+, Bluetooth mesh, Thread, and Zigbee products.

Lee Turner, global head of semiconductors and single board computing at Farnell said: “We are pleased to expand our PMIC range with the latest products from Nordic Semiconductor. The . . .  nPM1100 is an ideal solution to help our customers reduce energy consumption in their designs. The ability to charge small batteries and extend battery life while providing efficient power management within small, space constrained applications, such as wearables and connected medical devices, is now of critical importance.”

Rutronik adds Nordic Semiconductor’s PMIC

Tue, Jul 27, 2021

Offering efficient reliability in confined spaces, the Nordic nPM1100 is a dedicated power management IC (PMIC) with configurable dual-mode buck regulator and integrated battery charger. It is designed as a complementary component to Nordic‘s nRF52 and nRF53 series of SoCs and to ensure reliable power supply and stable operation while maximising battery life through high efficiency and low quiescent currents. It can also be used as a generic PMIC device, says Rutronik, which has added the nPM1100 to its portfolio.

The compact (2.075 x 2.075 mm) WLCSP package can be used in wearable devices, connected medical devices, smart home sensors and controls, remote controls and game controllers, and other size constrained applications, advises Rutronik.

The integrated battery charger is designed to charge lithium-ion and lithium-polymer batteries to a selectable termination voltage of 4.1 or 4.2V and supports cell chemistries with a nominal voltage of 3.6 or 3.7V respectively. The PMICe features thermal battery protection and automatic selection of three charging modes: automatic trickle charge, constant current and constant voltage.

The maximum charging current can be selected via a resistor from 20 up to 400mA. The charger also has a discharge current limiter and is JEITA-compliant.

The high-efficiency step-down regulator can deliver up to 150mA of current at a selectable output voltage of 1.8, 2.1, 2.7 or 3.0V. It features soft start and automatic transition between hysteresis and PWM modes. It also enables a forced PWM mode to ensure clean operation.

The nPM1100 has a low quiescent current, 700nA typical, 470nA in ship mode (deactivates the current output) and 150mA current limit. The PMIC also has over-voltage protection  and USB port detection for SDP, CDP and DCP.  There is also a driver for charging and error indication LED  and the nPM1100 evaluation kit.
