Current Limit 10 Click is a compact add-on board representing a current-limiting solution for your application. This board features the HS2950P, a load protection HotSwitch from Semtech. It features a wide input voltage range of 2.7V up to 29V and can provide up to 5A output current. The HS2950P features an adjustable current limit, over-voltage protection, automatic output discharge, and soft start. It automatically restarts from all faults except OVP and UVLO. This Click board™ makes the perfect solution for the development of telecommunication and networking equipment, office automation equipment, consumer products, and more.
Current Limit 10 Click is fully compatible with the mikroBUS™ socket and can be used on any host system supporting the mikroBUS™ standard. It comes with the mikroSDK open-source libraries, offering unparalleled flexibility for evaluation and customization. What sets this Click board™ apart is the groundbreaking ClickID feature, enabling your host system to seamlessly and automatically detect and identify this add-on board.

Availability date:
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.

We provide a library for the Current Limit 10 Click as well as a demo application (example), developed using MIKROE compilers. The demo can run on all the main MIKROE development boards.
Package can be downloaded/installed directly from NECTO Studio Package Manager (recommended), downloaded from our LibStock™ or found on Mikroe github account.
Library Description
This library contains API for Current Limit 10 Click driver.
Key functions
currentlimit10_set_limit
This function sets the desired current limit threshold using the I2C serial interface.
currentlimit10_get_fault
This function gets the state of the fault flag to indicate overcurrent, overtemperature, or reverse-voltage conditions.
currentlimit10_enable
This function turns on the power switch and enables the internal MOSFET.
Example Description
This library contains API for the Current Limit 10 Click driver for the current limiting to a certain value and displays the sources a current proportional to the load current [A].

Additional notes and informations
Depending on the development board you are using, you may need USB UART click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. UART terminal is available in all MIKROE compilers.
This Click board™ is supported with mikroSDK - MIKROE Software Development Kit. To ensure proper operation of mikroSDK compliant Click board™ demo applications, mikroSDK should be downloaded from the LibStock and installed for the compiler you are using.
For more information about mikroSDK, visit the official page.
NOTE: Please be advised that any peripheral devices or accessories shown connected to the Click board™ are not included in the package. Check their availability in our shop or in the YMAN section below.
