3.1.2 Adjustable Current Limit

The current limit of the device can be adjusted using an external resistor on the ILIM pin. The value, which is set by the ILIM pin, is applied to both channels. The device provides ILIM settings with a thermal regulated current limit, which adjusts the current limit level based on the relative temperature of the FET and the controller, to enable the device to charge up large capacitors at start-up. The device also offers ILIM settings without thermal regulation where the device limits the current at the set ILIM value.

The EVM can be designed to hold different current limit values through a potentiometer (R7) or resistor (R15).
