32 PRODUCT UPDATE Issue 1 2024 Power Electronics Europe www.power-mag.com with derating, depending on attached heatsink and airflow. Typically, the parts provide full load with a 20mm attached quarter brick heatsink up to 60°C ambient air temperature in natural convection and to around 90°C with 3m/s airflow. There is also programmable input under-voltage lockout, remote control, output trim and remote sensing. Comprehensive protection includes overtemperature, and output short-circuit, over-voltage and over-current. www.flexpowermodules.com Thermal management is a critical aspect of automotive design, yet compared to many other components, there is a noted lack of options when it comes to multi-channel remote temperature sensors. Microchip Technology has launched the MCP998x family of 10 automotive-qualified remote temperature sensors. The MCP998x family is perported to be one of the largest portfolios of automotive-grade multi-channel temperature sensors in the industry and is Multi-Channel Remote Temperature Sensors by Microchip Farnellhas added Nordic Semiconductors’ nPM1300 Power Management IC to its semiconductor portfolio to enhance the offering for connectivity of devices. The nPM1300 offers a simplified solution to system design by integrating essential functions that are necessary for embedded designs into a single, compact package. Its high efficiency power regulation provides designers with longer run times and efficient battery charging, while reducing the number of required components. The nPM1300i integrates many intelligent system management functions, including integrated hard reset functionality for one or two buttons, accurate battery fuel gauging, a system-level watchdog, power loss warning and recovery from failed boot. These functions are typically added using discrete components in Bluetooth Low Energy (LE) embedded designs, while the nPM1300 includes them in a single package. Key features of the nPM1300 Power Management IC include: 32 - 800 mA battery charger. Two 200 mA buck DCDC regulators. Two 100 mA Load switches, alternatively 50 mA LDO. Five GPIOs. ★ Three LED drivers. ★ Controlled via I2C compatible TWI. ★ USB-C compatibility. For more information, visit http://www.farnell.com/corporate Nordic Semiconductors’ Intelligent nPM1300 Power Management IC now available from Farnell designed for 1°C accuracy at a wide operational temperature range. The device family includes five sensors with shutdown temperature setpoints that are designed not to be overwritten by software or maliciously disabled. With up to five channels of monitoring and several alert and shutdown options for security, this product family claims to support systems that supervise more than one thermal element. The remote sensors also integrate resistance error correction and beta compensation, eliminating the need for additional configuration for improved accuracy. Monitoring temperatures at multiple locations with a single, integrated temperature sensor reduces board complexity and size and simplifies design for a lowered bill of material (BOM). Claimed More accurate where it counts, designed for 2.5°C accuracy up to 125°C, the MCP998x device family can be used at the high end of the traditional temperature range where many competitors are challenged. This high temperature tolerance makes them well-suited for automotive applications where operating temperatures for electronics is a major factor. The MCP998x sensors are designed to support vehicle functions including HID lamps, advanced driver-assistance system (ADAS), automotive servers, video processing, infotainment systems, engine control, telematics and body electronics such as seat control, lighting systems, mirror control and power windows.

The optocouplers provide low power consumption to save energy in industrial applications. The single-channel VOH260A, VOIH060A, and VOWH260A and dual-channel VOH263A and VOIH063A have a wide voltage supply range of 2.7 to 5.5V and an open collector output. They are for use with with low voltage microcontrollers and I?C and SPI bus systems, says the Vishay Semiconductors. Offered in DIP-8, SMD-8, and SOIC-8 packages, the optocouplers use an efficient input LED coupled to an integrated photodetector logic gate with a strobable output. The optocouplers combine a low supply current of 5mA maximum per channel with a low typical turn-on threshold current of 2mA typical, which simplifies designs by eliminating the need for an additional driver stage for a direct microcontroller connection. All five devices are suitable for data communications, high speed A/D and D/A conversion, level shifting and providing high voltage safety in automation equipment, motor drives and tools. They feature an internal shield that provides a guaranteed common mode transient immunity (CMTI) of 15kV/?s minimum. This means the optocouplers are also suitable for noise isolation and breaking up ground loops in these applications. The RoHS-compliant devices offer maximum rated withstand isolation voltage up to 5,000V RMS and provide isolation distances from 5.0 to 10mm to cover a wide range of requirements, including those of applications with working voltages exceeding 1,000V. Samples and production quantities are available now, with lead times of six weeks. www.vishay.com 10MBd optocouplers save energy in industrial applications
