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. […]

Automotive, industrial op amps operate to 175C
STMicroelectronics’ TSZ181H1 and dual TSZ182H1 automotive-qualified operational amplifiers (op amps) deliver high accuracy and stability over a wide (-40°C to 175°C) temperature range. The high maximum operating temperature encourages use in harsh environments and in applications with long mission profiles. The op amps have very low input offset voltage, typically 3.5µV at 25°Cm, and input bias current, typically 30pA […]
IR motion sensor also detects still object
STMicroelectronics is launching a novel human-presence and -motion detector to enhance security systems, home automation equipment, and IoT devices that typically use passive infrared (PIR) sensing. The STHS34PF80 sensor contains thermal transistors that can detect stationary objects, unlike conventional PIR detectors that require the detected object to be moving to produce a measurable response from the sensor. Also, while […]
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 […]
What are top applications of CAN protocol?
The CAN (controller area network) protocol was developed by the European automotive electronics company Robert Bosch GmbH in 1983 for in-vehicle networks. The intention behind the development of the CAN protocol was to enable robust data communication between different electronic control units (ECU) and microcontroller control units (MCU) of a vehicle on a single wire […]
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 […]
Waterproof pressure sensor provides digital memory and connunications
STMicroelectronics has introduced the market’s first MEMS water/liquid-proof absolute pressure sensor with a declared 10-year longevity program for the industrial market. ST’s new ILPS28QSW sensor comes in a sealed, cylindrical, surface-mountable package. It features a ceramic substrate that provides high resistance to liquid permeability and a robust potting gel, proven in automotive applications, to protect the […]
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 […]
MPU combine 64-bit core with AI engine
STMicroelectronics has introduced the second generation of its STM32 MPUs (microprocessors), coming with a new architecture built upon the same ecosystem and raising performance and security for applications at the industrial and IoT edge. The first product line in this new generation, the STM32MP25, is available with single or dual 64-bit Arm Cortex-A35 cores running efficiently at […]
