Table 1: Input/output truth table
Enable Input
The IRS26310D 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
IRS26310D features an input filter; the minimum input duration is specified by t FILTER,EN . Please refer to the EN pin
parameters V EN,TH+ , V EN,TH- , and I EN for the details of its use. Table 2 gives a summary of this pin’s functionality and
Figure 10 illustrates the outputs’ response to a shutdown command.
