When Rs input voltage exceeds inner reference voltage Vref(0.5V typical), this IC turns off the bottom output. After typ 200kΩ typ 220kΩ RS typ 300Ω S Latch R typ 5pF Vref overcurrent detection, a reset operation is done at each inner clock signal period. In case of not using this function, please connect Rs Inner Clock Trigger RS terminal inner equvalent circuit terminal to GL terminal. PDE-3064-0 ECN3064 6.
