Enable Input
The IRS2336xD family of HVICs is equipped with an enable input pin that is used to shutdown or enable the HVIC.
When the EN pin is in the high state the HVIC is able to operate normally (assuming no other fault conditions).
When a condition occurs that should shutdown the HVIC, the EN pin should see a low logic state. The enable
circuitry of the IRS2336xD features an input filter; the minimum input duration is specified by t
to the EN pin parameters V
functionality and Figure 11 illustrates the outputs’ response to a shutdown command.
