The FAN7080-GF085 is a half-bridge gate drive IC w ith
reset input and adjustable dead time control. It is
designed for high voltage and high speed driving of
MOSFET or IGBT, w hich operates up to 600 V. ON
Semiconductor'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 allow s
high-side gate driver operation up to VS=-5 V (typical) at
VBS=15 V. Logic input is compatible w ith standard
CMOS outputs. The UVLO circuits for both channels
prevent from malfunction w hen VCC and VBS are low er
than the specified threshold voltage. Combined pin
function for dead time adjustment and reset shutdow n
make this IC packaged w ith space saving SOIC-8
Package. Minimum source and sink current capability of
output driver is 250 mA and 500 mA respectively, w hich
is suitable for junction box application and half and full
bridge application in the motor drive system.

3 SD/DT VS 6
VDT = Vdd*R2 / (R1+R2). Vdd is output voltage of Microcontroller.
The operating range that allows a VDT range of 1.2~3.3V.
When pulled lower than VDT [Typ. 0.5V] the device is shutdown.
Care must be taken to avoid below threshold spikes on pin 3 that can cause undesired shut down of the IC.
For this reason the connection of the components between pin 3 and ground has to be as short as possible.
And a capacitor (Typ. 0.02µF )between pin3 and COM can prevent this spike. This pin can not be left
floating for the same reason.
