Hall-effect sensors survive under the
bonnet
Increased 12bit accuracy helps designers manage power train applications more precisely, thus reducing pollution and improving fuel economy.
Micronas has produced two new members of its varioHAL family of fully integrated Hall-effect sensors with digital interfaces enabling robust and reliable data transfer in harsh automotive environments The HAL 2830 and HAL 2850 include a microcontroller, a temperature sensor, advanced on-chip compensation and a digital output format
