Current Limit 7 Click Board
Current Limit 7 Click Board
Key Features:
- Integrated protection features, programmable current limiting up to 2.5A, operational and fault indicator, and more
- Based on the MAX14575A - programmable current-limit switch featuring internal current limiting to prevent damage to host devices due to faulty load conditions from Analog Devices
- Can be used for applications in portable equipment and condition monitoring or power supplies, protecting them in short circuits or other overload conditions
- mikroBUS: I2C and GPIO Interfaces
The Current Limit 7 Click Board™ is a compact add-on board representing a current-limiting solution. This board features the MAX14575A, an adjustable current-limit switch from Analog Devices. This Click board™ features internal current limiting to prevent damage to host devices due to faulty load conditions, has a low 32mΩ on-resistance, and operates from a 2.3V to 5.5V input voltage range. Also, the current limit is adjustable from 250mA to 2.5A programmed through AD5272 digital rheostat and set via onboard range switch. This Click board™ is suitable for applications in portable equipment and condition monitoring or power supplies, protecting them in short circuits or other overload conditions.
The Current Limit 7 Click Board™ is supported by a mikroSDK compliant library, which includes functions that simplify software development. This Click board™ comes as a fully tested product, ready to be used on a system equipped with the mikroBUS™ socket.
Software Support
We provide a library for the Current Limit 7 Click Board™ as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.
The package can be downloaded/installed directly from NECTO Studio The package Manager (recommended), downloaded from our LibStock™ or found on MikroE Github account.
Library Description
This library contains API for the Current Limit 7 Click Board™ driver.
Key functions
-
currentlimit7_set_current_limit
Current Limit 7 set current limit function. -
currentlimit7_set_resistance
Current Limit 7 set resistance function. -
currentlimit7_get_fault
Current Limit 7 get fault function.
Example Description
This library contains API for the Current Limit 7 Click Board™ driver. This driver provides the functions to set the current limiting conditions in order to provide the threshold of the fault conditions.

The full application code, and ready to use projects can be installed directly from NECTO Studio The package Manager (recommended), downloaded from our LibStock™ or found on MikroE Github account.
Other MikroE Libraries used in the example:
- MikroSDK.Board
- MikroSDK.Log
- Click.CurrentLimit7
Additional Notes and Information
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 MikroElektronika compilers.
MIKROSDK
The Current Limit 7 Click Board™ is supported with mikroSDK - MikroElektronika 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.
