* Values for R12VGATE and R3VGATE may vary
depending upon the CGS of the external MOSFETs.
# These components are not required for ISL6112
operation but can be implemented for GATE output
slew rate control (application specific).
• Bold lines indicate high current paths.
^ RSENSE value is application specific.
