Note 1.
“
+
”
sign shows the direction of current flow into the IC and
“–”
sigh shows the current flow
from the IC.
Note 2. This terminal has the constant voltage characteristic of 6V to 8V when current is supplied
from outside. The maximum allowable voltage is 6V when the constant voltage is applied
to this terminal. And maximum allowable current into this terminal is 5mA.
Note 3. The low impedance voltage supply should not be applied to the OVP terminal.
