Product data sheet
External resistor calculation
The output current can be set by connecting an external resistor between VS (pin 5) and
REXT (pin 4).
I
Without an external resistor the output current will be typically 15 A.
Typical output currents versus supply voltage V
The applied supply voltage determines the output current.
at specified supply voltages, assuming that the working output current is 70% of the
maximum possible output current.
