Positive Temperature (PTC) Heater System
NXPs robust product portfolio provides automotive MCU, sensor, interface solutions, and anti-tamper products for positive temperature coefficient (PTC) heater system and control applications, In an Electrical Vehicle, the PTC heater brings efficiency and safety to heating system. The PTC heater runs off the high voltage battery to maximize the power delivered to the heater. An IGBT or other high current power device is used to turn the heater on and off.
