* Note: These parameter values are proportional to V
. Values shown are at V
REF
= 5V; when different V
REF
values are used, these values should be scaled accordingly. For example
when operating at V
= 4V, multiply each of the asterisk values by 0.8.
The V
output is intended for use in gross overcurrent detection. For accurate current measurements V
should be used.
The equation below shows how the specifications are used to compute overall error in V
IRSENSE
. (
T is the change in ambient temperature from 25°C).
