2.This terminal has the constant voltage characteristic of 6 to 8V,when current is supplied from outside.The maximum allowable
3.The low impedance voltage supply should not be applied to the OVP terminal.
(ON duty)
voltage is 6V when the constant voltage is applied to this terminal.And maximum allowable current into this terminal is 5mA.
