Texas Instruments (TI) (NASDAQ: TXN) introduced what it said is the industry’s fastest 120-V automotive grade half-bridge gate driver with robust handling features.
The driver, UCC27201A-Q1, provides a propagation delay at 15ns with short rise and fall times and the tightest delay matching of 1ns for 12-V to 48-V DC/DC power supplies. The UCC27201A-Q1 high-side/low-side gate driver offers advanced noise tolerance, resulting in improved overall system performance for hybrid vehicles.

From Circuit Models to Real-Time Simulation – Fast and Easy
Thanks to the new dSPACE Power RealTime Library, it is now faster and easier to simulate circuit models that were developed in SimPowerSystems (MathWorks Simulink).
Two typical application areas are wind energy generators and electric drives in vehicles and aircraft.
The dSPACE Power RealTime Library provides mean value models of power electronics bridge circuits that precisely emulate the electrical characteristics of fast-switching power semiconductor devices.
Traveo™ family based on ARM® Cortex®-R5 core delivers advanced HMI, security and networking for automotive applications
Spansion Inc. announced a new family of microcontrollers targeted at automotive applications. The Spansion® Traveo™ microcontrollers are based on the ARM® Cortex®-R5 core and will deliver high performance, enhanced human-machine interfaces, high-security and advanced networking protocols tailored for automotive applications such as electrification, body electronics, battery management, automotive cluster displays, HVAC and ADAS.
The first product of the Spansion Traveo family, the MB9D560 series, features dual ARM Cortex-R5 cores with 2MB of embedded flash and operates at 200 MHz. The Spansion Traveo microcontrollers expand Spansion’s portfolio for vehicle electrification utilized in hybrid vehicles (HEV) and electrical vehicles (EV).

This article describes what start-stop is and the prerequisites for an automotive start-stop system, including its implementation and benefits.
The fuel savings and CO2 reductions are in the five to 10 percent range. With fuel prices rising, taxes increasing for high carbon-oxide emissions, and governmental requirements for vehicles with lower and lower emissions, various measures are needed to increase efficiency and lower emissions.
Infineon Technologies AG has introduced an innovative package technology that provides high-current capability and high efficiency for demanding automotive electronics applications, including electric and hybrid vehicles.
The new TO package is compliant with JEDEC standard H-PSOF (Heatsink Plastic Small Outline Flat lead). The first available products using the H-PSOF package technology are 40V OptiMOS™ T2 power transistors offering up to 300A current capability and R DS(on) values of 0.76mΩ. Infineon describes those specifications as a new milestone.
