High-side switches add less than 260 mΩ
STMicroelectronics has launched a family of octal high-side switches that combine galvanic isolation for robustness, RDS(on) below 260mΩ for energy efficiency and protection, and diagnostics for reliability and fault recovery. The 8-channel switches, ISO808, ISO808A, ISO808-1, and ISO808A-1, drive all types of industrial loads – capacitive, resistive, and inductive – with one side connected to the ground. Typical uses […]
High-side switches protect and diagnose motor circuits
STMicroelectronics’ IPS8160HQ and IPS8160HQ-1 high-side switches provide eight channels, in a compact QFN48L package, with the added value of built-in protection and diagnostics. This unique combination of features helps save space and enhance reliability in PLC modules used for driving heavy loads and unidirectional motors in vending machines. Further applications include I/O peripherals in factory automation equipment, computer numerical […]
Power windows: now much more than just a motor and switch, Part 2
The automotive power window has evolved from a basic on/off switch and motor to a sophisticated motion-control subsystem with dedicated ICs. As with most improvements, there are both expected and unanticipated ripple effects in product objectives, associated design, and actual production. As cars became increasingly “electrified” with more motors, switches, lighting, power seats, infotainment, advanced […]
APEC 2023 round-up
The Applied Power Electronics Conference (APEC) has grown over the course of a few decades to be the leading conference in North America for power electronics professionals. This past month, March 19th to the 23rd, in Orlando, APEC returned to share the latest trends, technologies, and opportunities in power electronics with industry and academia alike. […]
GaN converters targets SMPS
STMicroelectronics has extended its high-voltage wide-bandgap power converter family by adding the VIPerGaN100 and VIPerGaN65 for single-switch quasi-resonant (QR) flyback converters up to 100W and 65W. The compact and highly integrated design targets switched-mode power supplies (SMPS) for USB-PD chargers, home appliances, smart-building controllers, lighting, air conditioning, smart metering, and other industrial applications. Each device integrates a pulse-width […]
USB power delivery controller produces 140 W
STMicroelectronics has introduced the ST-ONEHP integrated digital controller, the world’s first IC certified by USB-IF according to the USB Power Delivery Extended Power Range (USB PD 3.1 EPR) specification. As the third controller in the ST-ONE family, the ST-ONEHP has 28V output capability to simplify building chargers and power adapters rated up to 140W. Sharing the […]
High-side gate drivers keep vehicles driving
STMicroelectronics has released single-, double-, and four-channel automotive high-side gate drivers in a common PowerSSO-16 package style, with pin assignments that simplify scaling circuit designs to add more driver channels. The gate drivers target applications throughout the vehicle, including safety, comfort, powertrain, body electronics, infotainment, and driver assistance systems. Meeting the automotive industry’s LV124 test schedule for […]
Flyback controller lights LEDs in 250 msec
STMicroelectronics’ HVLED101 90-400V flyback controller for LED-lighting applications up to 180W enhances performance and simplifies design through extensive feature integration, patented control techniques, and support for primary-sensing regulation. Joining ST’s HVLED family of high-power-factor controllers, the HVLED101 contains 800V startup circuitry that cuts the LED turn-on time to less than 250ms. High-voltage input-sensing circuitry and maximum power […]
USB-PD adapters supports two power outputs
STMicroelectronics is extending its highly integrated and power-saving ST-ONE family of USB Power Delivery (USB-PD) digital controllers by introducing the ST-ONEMP, which supports two power outputs. The ST-ONEMP builds on the market-first ST-ONE architecture combining an Arm Cortex-M0+ microcontroller, energy-efficient non-complementary active clamp flyback controller, and USB-PD 3.1 interface in a single package. Using galvanic […]
