FD and LIN buses enhance automotive power management IC
STMicroelectronics’ SPSB081 automotive power-management IC is a Swiss Army Knife of features including a main fixed-voltage low-dropout regulator (LDO), a secondary programmable LDO, four high-side drivers, a CAN FD transceiver[1], and an optional LIN transceiver[2]. The ICs provide multiple standby modes with very low quiescent current and programmable local or remote wake-up to help minimize power consumption. […]
GaN driver sinks and sources up to 3A gate current to connected transistor
STMicroelectronics’ first galvanically isolated gate driver for gallium-nitride (GaN) transistors, the STGAP2GS, trims dimensions, and bill-of-materials costs in applications that demand superior wide-bandgap efficiency with robust safety and electrical protection. The single-channel driver can be connected to a high-voltage rail up to 1200V, or 1700V with the STGAP2GSN narrow-body version, and provides gate-driving voltage up […]
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 […]
