Overcurrent

The current of the channel load circuit has exceeded half of the current that is admissible for the protective function of the fuse. If a current is flowing that is too high, the IC switch switches off internally. The magnitude of the current depends on the number of impulses and the energy over time.

Protection class	Description
Permanent overcurrent protection	Channel inactive at I_out min. >2,0 / typ. 2,3 / max. <2,7A
Surge current protection	Channel inactive at I_out * t_oc : e. g. I_out * t_oc -> 3Ax80ms / 5Ax33ms / 10Ax15ms / 20Ax7ms / 35Ax4ms (tolerance ±20%) t_oc = response time of the overcurrent protection

Protection class

Description

Permanent overcurrent protection

Channel inactive at I_out min. >2,0 / typ. 2,3 / max. <2,7A

Surge current protection

Channel inactive at I_out * t_oc :

e. g. I_out * t_oc -> 3Ax80ms / 5Ax33ms / 10Ax15ms / 20Ax7ms / 35Ax4ms (tolerance ±20%)

t_oc = response time of the overcurrent protection
