Description
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 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 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 applica-
tion and half and full bridge application in the motor drive sys-
tem.
