• Manufacturer Part Number: HCPL-316
• Description: 2.0 Amp Gate Drive Optocoupler with Integrated (VCE) Desaturation Detection and Fault Status Feedback
• Manufacturer: ETC

User-Configuration of the
HCPL-316J Input Side
The V
RESET input pins make a wide
variety of gate control and fault
configurations possible,
depending on the motor drive
requirements. The HCPL-316J
has both inverting and non-
inverting gate control inputs, an
open collector fault output
suitable for wired ‘OR’
applications and an active low
reset input.
