Connecting and Using the Fault Output

The IM483 has an open collector fault output located on P1:7. This output is

non-isolated and has the ability of sustaining maximum driver voltage. It can

sink a maximum of 25mA, which is sufficient to drive an LED or a small relay.

This output is active when in a LOW state. The following conditions will cause

this output to become active:

1] Phase-to-phase short circuit.

2] Phase-to-ground short circuit.

3] Phase over-current condition.

When the fault output becomes active, it disables the driver outputs and latches

in this condition. It can only be cleared by toggling the reset input LOW, or by

powering OFF then powering ON the drive.

Figure 7:10 illustrates the fault output connected to an LED.

NOTE! Once the fault output is active, it can only be cleared

by toggling the reset input LOW, or by powering off the driver.

NOTE! The IM483 driver outputs will disable in the event of an

over-temperature condition, however, in this case the fault

output WILL NOT latch. The driver will begin operating again

when the temperature drops below the shut-off threshold.
