User-Configuration of the HCPL-316J Input Side
The V
variety of gate control and fault configurations possible,
depending on the motor drive requirements. The HC-
PL-316J has both inverting and noninverting gate con-
trol inputs, an open collector fault output suitable for
wired ‘OR’ applications and an active low reset input.
Driving Input pf HCPL-316J in Non-Inverting/Inverting
Mode
The Gate Drive Voltage Output of the HCPL-316J can
be configured as inverting or non-inverting using the
V
non-inverting configuration is desired, V
by connecting it to GND1 and V

gled.
Local Shutdown, Local Reset
As shown in Figure 70, the fault output of each HCPL-
316J gate driver is polled separately, and the individual
reset lines are asserted low independently to reset the
motor controller after a fault condition.
Global-Shutdown, Global Reset
As shown in Figure 71, when configured for inverting op-
eration, the HCPL-316J can be configured to shutdown
automatically in the event of a fault condition by tying
the FAULT output to V
open collector FAULT outputs of each HCPL-316J can be
wire ‘OR’ed together on a common fault bus, forming a
single fault bus for interfacing directly to the micro-con-
troller. When any of the six gate drivers detects a fault,
the fault output signal will disable all six HCPL-316J gate
drivers simultaneously and thereby provide protection
against further catastrophic failures.
