Current Limit 10 Click

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.

Software Support

We provide a library for the Current Limit 10 Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for Current Limit 10 Click driver.

Example Description

This library contains API for the Current Limit 10 Click driver. This driver provides the functions to set the current limiting conditions in order to provide the threshold of the fault conditions.

The demo application is composed of two sections :

Application Init

Initialization of I2C module and log UART. After driver initialization, the app executes a default configuration and and sets the current limit threshold of 750 mA.

void application_init ( void )
{
log_cfg_t log_cfg;
currentlimit10_cfg_t currentlimit10_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
currentlimit10_cfg_setup( &currentlimit10_cfg );
CURRENTLIMIT10_MAP_MIKROBUS( currentlimit10_cfg, MIKROBUS_1 );
if ( I2C_MASTER_ERROR == currentlimit10_init( &currentlimit10, &currentlimit10_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
if ( CURRENTLIMIT10_ERROR == currentlimit10_default_cfg ( &currentlimit10 ) )
{
log_error( &logger, " Default configuration." );
for ( ; ; );
}
if ( CURRENTLIMIT10_ERROR == currentlimit10_set_limit( &currentlimit10, 0.75 ) )
{
log_error( &logger, " Current limit threshold." );
for ( ; ; );
}
log_info( &logger, " Application Task " );
Delay_ms ( 100 );
}

Application Task

This example demonstrates the use of the Current Limit 10 Click board. The demo application checks the fault flag for overcurrent conditions. Results are being sent to the UART Terminal, where you can track their changes.

void application_task ( void )
{
{
log_printf( &logger, "Fault flag: Overcurrent\r\n" );
}
else
{
log_printf( &logger, " Current limit is 0.75 A\r\n" );
}
Delay_ms ( 1000 );
}

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.CurrentLimit10

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 MikroElektronika compilers.
