HOW DOES IT WORK?
Current Limit 10 Click is based on the HS2950P, a load protection HotSwitch from Semtech. It utilizes flexible and programmable protection features and can handle multiple fault conditions. During fault conditions, automatic output discharge will be activated, thus protecting the load, and the HS2950P will automatically restart from a fault condition. The under-voltage lockout threshold is set to the default position (2.6V). The overvoltage protection can be externally set over the OVP SEL jumper, choosing between values 5.44V, 12.36V, and 24.13V. The OVP is set by default to 5.44V.
The current limit threshold can be set over the MAX5419, a nonvolatile digital potentiometer from Analog Devices. You can also choose the onboard external resistor for a fixed 0.5A value. The selection can be made over the ILIM SEL jumper. The soft start time is set to 0.32 ms, and the turn-on delay is set to 4 ms.
Current Limit 10 Click uses a standard 2-wire I2C interface of the MAX5419 to allow the host MCU to set the limit threshold. The HS2950P will alert the host MCU when the fault condition occurs over the FLT pin, along with the FLT LED indicator. Finally, you can turn off the current limiter over the enable EN pin.
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.
