Si85xx
3.3.6. Output Over-Range
The Si85xx can be over-ranged by more than 100% with no adverse effects. For instance, if the Si8512 (a 10 A
nominal full-scale device) has a 15 A peak current applied, then the output voltage (OUT) will be 3 V (assuming
VDD = 5 V). If a 10 A peak current is applied, then the output returns to the nominal 2 V output. The head room of
OUT is VDD–1.4 V. Figure 16 illustrates the head room limitation of the Si85xx versus supply.
