HOW DOES IT WORK?
Current Limit 9 Click is based on the NPS4053, a load switch with a precision adjustable current limit from Nexperia. It limits the output current to a constant current using a constant-current mode when the output load exceeds the current limit threshold or is shorted. An internal voltage comparator turns off the load switch to protect devices on the input side of the switch when the output voltage is higher than the input. The other protections include active reverse voltage protection, ILIM pin protection, ESD protection, and more.

The current to which you can set the limit over the Current Limit 9 Click board™ can be selected between external supply or 5V from the mikroBUS™ socket via the VIN SEL jumper. The external voltage can be in the range of 2.5 – 5.5V. It can use the MAX5419, a 256-tap 200K nonvolatile digital potentiometer from Analog Devices, to set the current limit threshold to the NPS4053 over the ILIM pin. It can also use an onboard R9 resistor for a fixed 0.5A at 5V supply. The selection can be made over the ILIM SEL.
Current Limit 9 Click uses a standard 2-Wire I2C interface of the MAX5419 to allow the host MCU to set the desired current limit threshold, which supports a fast I2C interface. You can turn the current limit IC on or off over the ON pin. The FLT is an interrupt pin, and it is asserted to a low logic level during overcurrent, overtemperature, and reverse-voltage conditions.
This Click board™ can operate with either 3.3V or 5V logic voltage levels selected via the VCC SEL jumper. This way, both 3.3V and 5V capable MCUs can use the communication lines properly. Also, this Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used as a reference for further development.
