Note 1."+" sign shows the direction of current flow into the IC and "-" sign shows the current flow from the IC.
2.This terminal has the constant voltage characteristic of 6 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.
3.The low impedance voltage supply should not be applied to the OVP terminal.
