LED Driver 13 Click Board
LED Driver 13 Click Board
Key Features:
- Designed at a switching frequency of 400kHz, operate in Boost or SEPIC mode for flexible output , provides 150mA per channel, programmable boost frequency, selectable LED Dimming feature, onboard protection circuitry, and more
- Based on the A80604-1 - multi-output LED driver for automotive applications from Allegro Microsystems
- Can be used for various automotive applications, such as infotainment backlighting, interior/exterior lighting, heads-up display, and more
- mikroBUS: PWM and GPIO Interfaces
The LED Driver 13 Click Board™ is a compact add-on board that simplifies the control of multiple LEDs. This board features the A80604-1, a 4-channel LED driver designed at a switching frequency of 400kHz that provides 150mA per channel from Allegro Microsystems. It is powered by an external power supply in the range of 6V to 18V, providing an output voltage of approximately 26V, which is used to power LEDs connected to LED channels. On the logical side, this board uses both 3V3 and 5V with mikroBUS™ power rails and communicates with the MCU via GPIO pins. In addition, the user is given the option of analog or digital LED dimming selection, using a PWM pin from the mikroBUS™ socket or via an onboard potentiometer/external PWM signal. This Click board™ is suitable for various automotive applications, such as infotainment backlighting, interior/exterior lighting, heads-up display, and more.
The LED Driver 13 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 LED Driver 13 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.

Example Description
This library contains API for the LED Driver 13 Click Board™ driver.
void application_task ( void )
{
static int8_t duty_cnt = 1;
static int8_t duty_inc = 1;
float duty = duty_cnt / 1000.0;
leddriver13_set_duty_cycle ( &leddriver13, duty );
log_printf( &logger, "> Duty: %.1f%%rn", duty * 100 );
Delay_ms( 100 );
if ( 30 == duty_cnt )
{
duty_inc = -1;
}
else if ( 0 == duty_cnt )
{
duty_inc = 1;
}
duty_cnt += duty_inc;
}
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.LEDDriver13
Additional Notes and Information
Depending on the development board you are using, you may need a 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 LED Driver 13 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.
