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.

Direct Insight creates QNX 7 BSP for Toradex Colibri iMX8X SoC modules

Thu, Jul 22, 2021

Systems integrator and system on module (SoM) reseller, Direct Insight, has created a QNX 7 board support package (BSP) for Toradex’s Colibri iMX8X embedded computing modules. They feature-rich QNX OS with real-time capability combined with the i.MX 8X processors can be used for mission critical applications such as medical devices, navigation, industrial automation, HMIs, avionics, POS, data acquisition and robotics.

Toradex Colibri iMX8X modules feature the NXP i.MX 8X family of embedded SoCs, including the i.MX 8QuadXPlus (i.MX 8QXP) which has four Cortex-A35 cores as the main processor cluster. The SoCs provide full 64-bit Arm v8-A support while maintaining seamless backward compatibility with 32-bit Armv7-A software. The main cores run at up to 1.2GHz.

According to David Pashley, Direct Insight’s managing director: “QNX is perfect for real time, safety critical applications,” he added that the BSP created by Direct Insight provides a great starting point for high availability industrial designs.

The QNX 7 BSP for Toradex’s Colibri iMX8X contains all the basic features required to run the OS on the board, such as drivers for various interfaces including Ethernet, Watchdog timer, I2C, SPI, USB, SD card and UART. A display driver is also planned.

The BSP is free to download as a demo system, and the source code can be licensed on a per-project basis for an affordable fee. Direct Insight also offers enhancements to the BSP, including additional drivers and production-hardening and testing.

Daniel Lang, chief medical officer at Toradex, added: “We design products for applications that demand high reliability, safety and security, such as medical devices. The QNX offering from Direct Insight further strengthens this positioning and allows our customers to use QNX while lowering the project risk and shortening the time-to-market.”

Founded in 1992, UK-based technical systems integrator and reseller of system on module (SoM) and other embedded systems, Direct Insight helps development teams to upgrade to the latest SoC, FPGA and OS technology by choosing the right off-the-shelf hardware, software and tools. It also provides support and services to fill the gaps, allowing customer development teams to focus on differentiating core skills.

Key partners include QNX, Ka-Ro Electronics, the German designer and manufacturer of embedded modules; and Taiwanese single board computer maker, DFI.

Hand-held camera cube reference design brings AI to the edge

Wed, Jul 21, 2021

Artificial intelligence (AI) which was previously limited to expensive machines with large power budgets can now be embedded in space-constrained, power-powered edge devices. Maxim Integrated says its MAXREFDES178# camera cube executes low latency AI vision and hearing inferences on a coin cell power budget with reduced cost and size.

The MAXREFDES178# enables low power IoT devices to implement hearing and vision. It is based on the MAX78000 low power microcontroller with neural network accelerator for audio and video inferences. The system also contains the MAX32666 low power Bluetooth microcontroller and two MAX9867 audio codecs. The system is delivered in a compact form factor to show how AI applications, such as facial identification and keyword recognition, can be embedded in low power, cost sensitive applications such as wearables and IoT devices.

AI applications require intensive computations, which is usually performed in the cloud or in expensive, power-hungry processors: self driving cars is an example. Maxim says that its MAXREFDES178# camera cube demonstrates how AI can operate on a low power budget, enabling applications that are time- and safety-critical to run on even the smallest of batteries. The MAX78000’s AI accelerator slashes the power of AI inferences up to 1,000x for vision and hearing applications, compared to other embedded solutions, reports Maxim. The AI inferences running on the MAXREFDES178# also show dramatic latency improvements, running more than 100x faster than on an embedded microcontroller.

The compact form factor of the camera cube (1.6 x 1.7 x 1.5inch of 41 x 44 x 39mm) allows AI to be implemented in wearables and other space-constrained IoT applications. The MAX78000 is up to 50 per cent smaller than the next-smallest GPU-based processor, says Maxim, and does not require other components like memories or complex power supplies to implement cost-effective AI inferences.

The MAXREFDES178# and the MAX78000 is available now, together with the MAX32666GWPBT+T RF microcontroller and the MAX9867EWV+T stereo codec at Maxim Integrated’s website and authorised distributors.
