Features
• Qualified to AEC Q100
Half Bridge Gate Driver
Description
The FAN7080_F085_F085 is a half-bridge gate drive IC with reset input and adjustable dead time control. It is designed for high voltage and high speed driving of MOSFET or IGBT, which operates up to 600V. Fairchild's high-voltage process and common-mode noise cancellation technique provide stable operation in the high side driver under high-dV/dt noise circumstances. An advanced level-shift circuit allows high-side gate driver operation up to VS=-5V (typical) at VBS=15V. Logic input is compatible with standard CMOS outputs. The UVLO circuits for both channels prevent from malfunction when VCC and VBS are lower than the specified threshold voltage. Combined pin function for dead time adjustment and reset shutdown make this IC packaged with space saving SOIC-8 Package. Minimum source and sink current capability of output driver is 250mA and 500mA respectively, which is suitable for junction box application and half and full bridge application in the motor drive system.
• Floating channel designed for bootstrap operation fully operational to + 600V • Tolerance to negative transient voltage on VS pin • VS-pin dv/dt immune. • Gate drive supply range from 5.5V to 20V • Under-voltage lockout • CMOS Schmitt-triggered inputs with pull-down • High side output in phase with input • IN input is 3.3V/5V logic compatible and available on 15V input • Matched propagation delay for both channels • Dead time adjustable
Typical Applications
• Junction Box • Half and full bridge application in the motor drive system
