It is the value of current which flows in the heavy load protection circuit when in the heavy load protection mode
(OSC3 ON or buzzer ON).
The value in x V can be found by the following expression: ISVDN (VDD = x V) = (x × 20) - 30 (Typ. value),
ISVDN (VDD = x V) = (x × 30) - 30 (Max. value
)
When OSC1 CR oscillation circuit is selected by the mask option.
