Equipped with state-of-the-art technology, Littelfuse’s LQ050XX integrated load switch ICs offer the industry’s highest performance with ultra-low power consumption. They make it possible to reduce parasitic leakage currents, improve system efficiency, and extend battery life. That means a real upgrade for a wide range of applications, e.g. in wearables, smart homes, or IoT devices.

The integrated load switch ICs are available in different housing sizes from 0.77 mm x 0.77 mm x 0.46 mm to 0.97 mm x 1.47 mm x 0.55 mm. Their small size makes them particularly suitable for applications with limited space. The switches are robust, particularly power-saving and, thanks to the cutting-edge technology they contain, can deliver market-leading performance in terms of low quiescent current and switch-off current. In addition, they impress with low power losses and reduced leakage currents for extremely convincing efficiency.

The ICs are available in the following versions:
LQ05021QCS4:
The load switch delivers 2 A rated power. The integrated slew rate control improves system reliability and reduces voltage fluctuations on the bus. Together with its outstanding efficiency, this makes it the ideal solution for applications such as IoT or wearables.
LQ05021RCS4:
The IC has a high efficiency and the leading True Reverse Current Blocking (TRCB) technology. Together with a particularly low threshold voltage, the LQ05021RCS4 prevents reverse current when Vout exceeds Vin, minimises power loss during operation, and offers an extremely low switch-off current. The switch is predestined for wearables, portable electrical devices, or IoT applications.
LQ05022QCS4:
This switch is also equipped with slew rate control, which limits the inrush current and thus minimises the voltage drop. The LQ05022QCS4 supports a wide input voltage range, which optimises both the service life and the reliability of a system. The component can also be used in different voltage rails. Preferred applications include data storage, IoT devices, or low-power subsystems.
LQ05041QCS6
The LQ05041QCS6 has a rated power of 4 A. It has an integrated slew rate control and also a slew rate control. With six bumps and a size of 0.97 mm x 1.47 mm x 0.55 mm, it is particularly small and is primarily used in data storage, or the medical sector.
LQ05041RCS6
With its leading TRCB technology and extremely low threshold voltage, the switch prevents reverse currents and minimises power loss during operation. Its main areas of application include portable devices and power-saving subsystems.

New adapter board from Rutronik enables centimetre-precise positioning in real-time

Thu, Mar 14, 2024

Precise positioning has become increasingly important in many areas and applications. Real-Time Kinematic (RTK) offers significantly greater accuracy than conventional multi-GNSS systems and continues to grow in cost-effectiveness. Together with the Rutronik Wireless Competence Centre Rutronik System Solutions have developed the Adapter Board RAB4, which facilitates testing the performance of RTK without designing any hardware. By accelerating the pre-development phase and reducing costs, the RAB4 helps to bring applications to market faster.
Autonomous vehicles, drones, and also agricultural machines rely on accurate positioning in real-time. RTK increases the precision of satellite system positions using a base station that sends correction data to a moving receiver. That allows an accuracy of one to two centimetres, even with fast-moving objects. “RTK is not a new technology and has been used in some areas for a long time. However, the costs were very high until now. Nowadays, cheaper but nevertheless powerful modules are available. That makes the technology and its advantages interesting for other areas of application.

The high-precision UM980 RTK positioning module from Unicore Communications uses the latest generation of the NebulasIV GNSS SoC, offers a high positioning rate, and supports all available GNSS frequencies. It is ideal for navigation and positioning applications.

For absolute positioning, a 4G LTE module with an integrated standard multi-GNSS receiver from Telit Cinterion’s LE910 series is integrated on the Adapter Board. Another advantage is that the integration of a GNSS and RTK receiver makes it possible to compare the outputs directly with each other without having to use several development kits from different suppliers. The RAB4 also includes a 100 MB prepaid SIM card. Thanks to this combination, NTRIP correction data can be downloaded from the Internet. It is not necessary to operate an own reference station.

Thanks to the Arduino interface, the RAB4 is easy to combine with other boards like the RDK3 from Rutronik System Solutions, a Base Board that allows wireless connections to be realized using Bluetooth Low Energy. The application example from Rutronik System Solutions demonstrates how the connection works. Using this example, a rover was developed in-house that can be controlled with centimetre precision via an app. It will celebrate its premiere at the Rutronik booth at embedded world 2024 in Nuremberg.

ST’ high-performance microcontrollers pave the way to new innovations in smart home and industrial systems

Wed, Mar 13, 2024

ST has revealed a new high-performance device that combines performance, scalability and security of microprocessor-based systems that are typically more complex with the simplicity and integration of microcontrollers (MCUs).

Using these new STM32H7 MCUs, producers of equipment like smart appliances, smart-building controllers, industrial automation, and personal medical devices can evolve their products more quickly and cost effectively as end-users’ demands continue to increase. Examples include adding richer, colourful user interfaces and performing multiple functions simultaneously, which is usually achieved with microprocessors (MPU).

ST’s new STM32H7R and STM32H7S microcontrollers come with robust security features, needed to address Internet of Things (IoT) applications. They include protection against physical attacks, memory protection, code isolation to protect the application at runtime, and platform authentication. The STM32H7S devices provide further security enhancement by integrating immutable root of trust, debug authentication, and hardware cryptographic accelerators that support the latest algorithms to prevent unauthorised access to code and data. With these security features, the devices are targeting up to SESIP3 and PSA Level 3 certifications, meeting the highest industry standards for cyber protection.

The STM32H7 MCUs combine the highest-performing Arm Cortex-M core ST has yet announced (Cortex-M7 running at up to 600MHz) with minimal on-chip memory and high-speed external interfaces. They let engineers build systems with extra performance and flexibility using simple, low-cost microcontroller development tools. The devices available are further divided into the STM32H7R3/S3 general-purpose MCUs and the STM32H7R7/S7 with enhanced graphics-handling capabilities. Developers can share software extensively between the two lines, enabling efficient use of project resources and faster time to market for new products.

ST’s new STM32H7 MCUs are scheduled to enter volume production from April 2024. Sample requests and pricing information are available from local ST sales offices.

The STM32H7S8-DK demonstration and development platform, and the affordable and extendable NUCLEO-H7S3L8 MCU board, are available to accelerate building applications using the new devices.
