xEV Powertrains

This article will discuss two new innovative approaches to measure currents up to 600 A in PCB: a near-lossless Hall-based current sensor with an integrated conductor and a non-invasive standalone core-free and shield-free differential Hall current sensor.

From high-voltage (HV) inverters and traction motors, to HV converters and transmissions, to on-board chargers (and beyond), our portfolio includes a suite of current sensors, gate drivers, DC-DC regulators, and power management integrated circuits (PMICs) for a multitude of electrified vehicle (EV) applications.

This article discusses how using a common platform for both 12V and 48V starter generator systems will simplify and ease the transition to 48V solutions, as the electrical revolution continues to transform the automotive industry.

AN296217 - This application note describes how to switch between buck enabled and buck disabled operation on any variant of the AMT49100 or AMT49101 gate diver family.

This application note discusses LED headlights for two-wheelers, passenger vehicles, commercial vehicles, and mild hybrid vehicles, and explores battery voltage and power requirements for the headlights used in these vehicles.

Our advanced sensor and power IC solutions are engineered specifically to meet the unique requirements of these designs, providing superior performance and reliability in harsh environments and under complex operating conditions.

This application note describes the mathematics to convert the analog sine/cosine outputs of the A33230 into an angular position.

Governments around the world, including the European Union and the United States, have placed mandatory fuel economy standards on combustion engines to reduce emissions. These initiatives will require innovative advances in technologies, driving the demand for increased efficiencies.

The Allegro™ A1366 linear Hall-effect sensor IC has been designed to meet the high bandwidth, high accuracy requirements of HEV inverter applications.

Improved energy efficiency in HEVs and EVs can be attained by using electrically-driven actuators instead of belt-driven and hydraulic actuators. For instance, in traditional internal combustion engines a fan belt drives the cooling fan, which operates continuously while the engine is running.

This note provides an understanding of hybrid electric vehicle (HEV) power systems and the contribution Hall-effect sensing technology can provide to improving the performance and cost-effectiveness of these systems.

Powering the Future of Electrification. Electric vehicles demand compact, efficient, and safe solutions—and Allegro delivers. Our technologies support key systems like battery management, on-board charging, DC-DC conversion, and traction inverters. We offer high-accuracy current sensors, high-voltage gate drivers, automotive PMICs, and precise position sensors, all designed for ISO 26262 compliance, best-in-class thermal performance, and easy system integration.

AN296266 - The use of a noncontact, active, speed sensor integrated circuit (IC) greatly simplifies system design-in of a magnetic speed sensor. Although these ICs are designed to operate under a wide variety of system factors, the cautious automotive designer must contemplate certain more-subtle system considerations.

Allegro pioneers the first back-biased GMR Sensor with 50% larger air gaps. This larger air gap operation enables smaller and lighter transmissions that achieve reduced fuel consumption to help meet today's fuel economy standards.

AN296231 - This application note focuses on how a busbar should be designed to achieve optimum performance with the ACS37610 coreless current sensor.
