Table 8. VCC - Output Diode

Table 9. Status Pin

Table 10. Protections (see note 1)

Note: 1. To ensure long term reliability under heavy overload or short circuit conditions, protection and related diagnostic signals must be

used together with a proper software strategy. If the device operates under abnormal conditions this software must limit the duration

and number of activation cycles.
