Gate Driver from Fairchild offers reliability and space savings

This HVIC saves at least 50 percent PCB area compared to optocoupler-based or pulse transformer-based solutions, and eliminates a buffer transistor compared to other low current HVICs on the market. Fairchild’s FAN7371 is the optimal solution for driving MOSFETs and IGBTs in a wide array of applications up to 600V including plasma display panel (PDP), high intensity discharge (HID) lighting, induction heating and other general purpose inverter applications.

The FAN7371 further increases reliability by providing under-voltage lockout (UVLO) for VBS and a built-in 25V shunt regulator. In addition, the FAN7371 features the industry’s lowest temperature dependency, ensuring stable performance against fluctuating temperatures in harsh environments. To enhance efficiency, this high voltage gate driver offers a floating channel designed for bootstrap operation up to +600V. When coupled with Fairchild’s MOSFETs and IGBTs, it provides a full system power optimization solution.

The FAN7371 is part of Fairchild’s comprehensive portfolio of HVIC solutions that provide excellent system reliability, stable performance and space savings for inverter motors, PDP sustain and energy recovery drivers, HID inverters, backlight inverters for CCFL, fluorescent lamp ballasts and class D audio amplifiers.

The FAN7371 utilizes lead-free (Pb-free) terminals and has been characterized for moisture sensitivity in accordance with the Pb-free reflow requirements of the joint IPC/JEDEC standard J-STD-020.
