* Values for R_12VGATE and R_3VGATE may vary
depending upon the C_GS of the external MOSFETs.
# These components are not required for ISL6113/4
operation but can be implemented for GATE output
slew rate control (application specific)
• Bold lines indicate high current paths
^ R_SENSE value is application specific
