PRODUCTION DATA
A high-power resistor can be used for sensing the boost input current. Overcurrent condition is detected when the voltage across RISENSE reaches 220 mV. Typical 20-mΩ sense resistor is used to set 11-A input current limit. Sense resistor value can be increased to lower overcurrent limit for application as needed. Power rating can be calculated from the input current and resistance value.
