Current detection amp input
Current detection amp output current
Current detection amp gain
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.
