5.3 Overcurrent Limiting Operation
This IC detects overcurrent by outside resistance Rs.
When Rs input voltage exceeds inner reference voltage
Vref(0.5V typical), this IC turns off the bottom output. After
overcurrent detection, a reset operation is done
at each inner clock signal period.
In case of not using this function,
please connect Rs
terminal to GL terminal.
