SolidSwitch 3 click

SolidSwitch 3 Click is a compact add-on board that contains a load switching device. This board features the BD8LB600FS-C, an automotive eight-channel low-side switch from Rohm Semiconductor. Every switch is controlled via an SPI interface and includes an N-channel MOSFET that supports a maximum current of 1A. The BD8LB600FS-C also has built-in protection circuits, namely the overcurrent, the thermal shutdown, the open-load detection, and the voltage lock-out circuits. Moreover, this device also possesses a diagnostic output function during abnormal detection.

Software Support

We provide a library for the SolidSwitch 3 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 SolidSwitch 3 Click driver.

Standard key functions :

Example key functions :

Example Description

This example demonstrates the use of SolidSwitch 3 click board by controlling the output state.

The demo application is composed of two sections :

Application Init

Initializes the driver and performs the click default configuration.

void application_init ( void )
{
log_cfg_t log_cfg;
solidswitch3_cfg_t solidswitch3_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
solidswitch3_cfg_setup( &solidswitch3_cfg );
SOLIDSWITCH3_MAP_MIKROBUS( solidswitch3_cfg, MIKROBUS_1 );
if ( SPI_MASTER_ERROR == solidswitch3_init( &solidswitch3, &solidswitch3_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
if ( SOLIDSWITCH3_ERROR == solidswitch3_default_cfg ( &solidswitch3 ) )
{
log_error( &logger, " Default configuration." );
for ( ; ; );
}
log_info( &logger, " Application Task " );
}

Application Task

Enables all outputs one by one in the span of 8 seconds, and after that disables

all outputs for 3 seconds. Accordingly, the outputs status will be displayed on the USB UART.

void application_task ( void )
{
for ( uint16_t cnt = SOLIDSWITCH3_CH_OUT1; cnt <= SOLIDSWITCH3_CH_OUT8; cnt <<= 1 )
{
if ( SOLIDSWITCH3_OK == solidswitch3_enable_output ( &solidswitch3, cnt ) )
{
solidswitch3_display_enabled_channels( &solidswitch3 );
Delay_ms ( 1000 );
}
}
{
solidswitch3_display_enabled_channels( &solidswitch3 );
Delay_ms ( 3000 );
}
}

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.SolidSwitch3

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.
