ELECTRICAL CHARACTERISTICS (cont’d)

Table 8. Protections and Diagnostics

Note: 6. IOL(off) = (VCC -VOL)/ROL (see figure 5).

7. t1(on): minimum open load duration which activates the status output;

t1(off): minimum load recovery time which desactivates the status output;

t2(off): minimum on time after thermal shut down which desactivates status output;

tpovl tpol: ISO definition (see figure 6).
