PTC Heaters

Heating up the cabin of hybrid and battery electric vehicles can be challenging. Positive temperature coefficient (PTC) heaters offer efficiency, dependability, and can eliminate any risk of overheating – improving passenger comfort and safety in 48V systems and optimizing charging for longer range in high voltage (HV) systems.

Allegro offers compact solutions, including half-bridge gate drivers with high isolation, current sensors, and EMC-compliant safety-focused DC/DC regulators, to provide customers with reliable and safe solutions that reduce their overall PTC heater footprint.
