Aitech Systems has released a high-efficiency U-P2330 power supply card (PSC) to support the power requirements of The Open Group Sensor Open Systems Architecture (SOSA). As a compatible power supply for a range of SOSA single-board computers (SBCs) and GPGPU-based boards, the new 3U PSC can be easily integrated as the main power supply in these open standards-based embedded systems, said the company. Key specs include a high-power output of up to 600 W and high efficiency up to 88%. In addition, the PSC can integrate an optional sharing mechanism, per VITA 62, which enables two power supplies to be operated in parallel and provides redundant operation (ORing) with a maximum power output of up to 1200 W, said the company. It also offers an optional holdup capacitor bank that can shut down the system in the event of power outage, while the supply redundancy protection ensures high-power-supply resiliency. The PSC is compliant with MIL-STD-704 and MIL-STD-1275.

Ceva, Inc. has added the FSP201 high-performance and low-power sensor hub MCU to its family of sensor fusion products. The new MCU delivers precise, accurate sensor fusion for motion tracking, heading, and orientation detection and can be used in consumer robotics and other emerging smart devices that use sensor fusion technologies, including XR glasses, 3D audio headsets, and six-axis motion use cases across IoT and the metaverse. The FSP201 combines the company’s MotionEngine sensor processing software with a low-power 32-bit Arm Cortex M23 MCU. It offers manufacturers the flexibility to choose from a pre-qualified list of external six-axis IMU sensors (accelerometer plus gyroscope) from different sensor suppliers and to provide features such as correction smoothing, auto-centering, tilt independent heading, inclination detection (full 3DOF robot orientation), and dynamic calibration. It uses I2C and UART industry interfaces for chip connectivity. For greater flexibility, the device can be placed directly on the product’s main circuit board or designed into a separate module. The FSP201 is code-compatible with the BNO08X series of nine-axis sensor system-in-package (SIP) products, which makes it easier for developers to migrate to a 6-axis-based solution that do not require nine-axis sensor fusion, said Ceva. The FSP201 is available for sampling along with documentation and evaluation tools via the company’s designated distributors.

Diodes Inc. has extended its portfolio of USB power delivery (PD) solutions with two new high-performance USB PD3.0 sink controller ICs. The AP33771 and AP33772 sink controllers target home appliances and cordless power tools, enabling the appropriate voltage level via USB-C. They have an operating voltage range of 3.3 V to 24 V. The AP33771’s pin-driven setting of required voltages and power makes it easier to use, while the AP33772 provides greater flexibility for more sophisticated designs that use a µC (with an I²C interface included), said the company. The AP33771’s preloaded power menu consists of eight different output voltages and 10 different power levels. It also provides 5-V charging when connected to a classic USB Type-A charger, as well as supporting USB Type-C to USB Type-C cable voltage drop compensation. These new products have built-in application firmware for automatic PD3.0 negotiation with the attached USB PD3.0 compliant charger to obtain the required power level. LED lighting (driven by one of their GPIOs) enables indication of the charging state and potential fault situation. Both devices, supplied in 24-pin W-QFN4040 packages, are priced at $0.5201 in quantities of 1,000. Evaluation boards are available through Diodes’ sales channel on request.
