Description
The FAN7842, a monolithic high and low side gate drive
IC, which can drive MOSFETs and IGBTs that operate up
to +200V.
Fairchild’s high-voltage process and common-mode
noise canceling technique provide stable operation of the
high-side driver under high-dv/dt noise circumstances.
An advanced level-shift circuit allows high-side gate
driver operation up to VS=-9.8V (typical) for VBS=15V.
The input logic level is compatible with standard TTL-
series logic gates.
The UVLO circuits for both channels prevent malfunction
when VCC and VBS are lower than the specified thresh-
old voltage. Output driver current (source/sink) is typi-
cally 350mA/650mA, respectively.
