Table 1: Input/output truth table
Enable Input
The AUIRS2336S 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
AUIRS2336S 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 11 illustrates the outputs’ response to a shutdown command.
