PRODUCTION DATA
The output current limit is programmable by placing a current sensing resistor between the ISP pin and ISN pin. The voltage limit between the ISP pin and the ISN pin is set to 50 mV. Thus a smaller resistance gets higher current limit and a bigger resistance gets lower current limit.
Connecting the ISP and the ISN pin together to the VOUT pin disables the output current limit because the sensed voltage is always zero.
