On-Board Chargers

We’re moving fast charging forward with solutions that make on-board chargers (OBC) safer, more efficient, and reliable. 

Our current sensors offer galvanic isolation from high voltage and near 1μs short circuit detection, along with the ability to track IGBT fast switching current (>1000kHz) to achieve high efficiency safely. Want to make your fast charger even safer? For charger locks, our 80V gate driver and integrated full bridge enable safe disconnect.

Check out our innovative current sensors, grade 0 regulators, and gate drivers for OBC.
