FAN7380/FAN7382
Half-Bridge Gate Drivers, FAN7380 and FAN7382, Offer Excellent Reliability and Industry's Lowest Power Consumption for Appliance, Display and Ballast Applications
These high-performance half-bridge gate driver ICs, FAN7380 and FAN7382, ensure exceptional system reliability and efficiency in a range of consumer and industrial applications. The FAN7380 and FAN7382 significantly improve system reliability by utilizing an innovative common mode dv/dt noise canceling circuit that provides excellent noise immunity. These components deliver an advanced level shift circuit permitting industry-leading, high-side driver operation with negative VS swings of up to -9 V (@ VBS=15 V). Both products feature the industry's lowest quiescent currents resulting in extremely low power consumption. With a voltage capability up to 600 V and a very fast switching speed [dv/dt = 50 V/ns (max)], these devices are optimal for driving MOSFETs and IGBTs in a wide array of applications including air conditioners, washing machines, LCD monitors, electronic ballasts and industrial motor controls.
