*Current limit 1 and 2 are prescribed by the current detection resistor voltage drop range.
*If the control on this IC fails to work, its safety can not be guaranteed. Please protect with something other
than this IC.
*Please use a capacitor with good temperature characteristics in the OSC section. Capacitor deviation
causes timer error.
