Hall Effect Current Sensing in Hybrid Electric Vehicle (HEV) Applications
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.
Application Note
Advanced Hall-Effect Linear Current Sensor IC Enables High BW Sensing in Hybrid Electric Vehicles and other High Current Sensing Applications
The Allegro™ A1366 linear Hall-effect sensor IC has been designed to meet the high bandwidth, high accuracy requirements of HEV inverter applications.
Application Note
Hall Effect Current Sensing in Electric and Hybrid Vehicles
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.
Application Note
System-Level Application Considerations for Magnetic Speed Sensors
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.
