FAN7081_F085
High Side Gate Driver
Features
• Qualified to AEC Q100
• Floating channel designed for bootstrap operation up fully
operational to + 600V
• Tolerance to negative transient voltage on VS pin
• dV/dt immune.
• Gate drive supply range from 10V to 20V
• Under-voltage lockout
• CMOS Schmit-triggered inputs with pull-up
• High side output out of phase with input (Inverted input)
Typical Applications
• Diesel and gasoline Injectors/Valves
• MOSFET-and IGBT high side driver applications
Description
The FAN7081_F085 is a high-side gate drive IC designed for
high voltage and high speed driving of MOSFET or IGBT, which
operates up to 600V. Fairchild's high-voltage process and com-
mon-mode noise cancellation technique provide stable opera-
tion 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 cir-
cuits prevent from malfunction when VCC and VBS are lower
than the specified threshold voltage. It is available with space
saving SOIC-8 Package. Minimum source and sink current
capability of output driver is 250mA and 500mA respectively,
which is suitable for magnetic- and piezo type injectors and gen-
eral MOSFET/IGBT based high side driver applications.
