Le Carte à clic PROFET™ -10A est une carte complémentaire compacte qui contient un commutateur d'alimentation côté haut intelligent. Cette carte comprend le Profet™ BTS7008-1EPA, un commutateur d'alimentation côté haut à double canal avec fonction de protection et de diagnostic intégrée d'Infineon Technologies. Ce commutateur a une capacité de pilotage adaptée aux charges de 7,5 A et aux charges à courant d'appel élevé et dispose d'un ReverSave™, qui provoque l'activation du transistor de puissance en cas d'inversion de polarité. Outre ses fonctions de protection, il dispose également de plusieurs fonctions de diagnostic configurables par broches telles que la détection de courant de charge proportionnelle, la charge ouverte en état ON et OFF, et le court-circuit à la terre et à la batterie.
Le PROFET™ -10A Click Board™ convient aux charges résistives, inductives et capacitives, remplaçant les relais électromécaniques, les fusibles et les circuits discrets, et bien d'autres.
How Does The PROFET -10A Click Board™ Work?
The PROFET -10A Click Board™ as its foundation uses the BTS7008-1EPA, a single-channel, smart high-side power switch with embedded protection and diagnosis feature from Infineon Technologies. The BTS7008-1EPA has a driving capability suitable for 10A loads and comes equipped with "ReverseON" functionality which causes the power transistor to switch on in case of reverse polarity. It also offers outstanding energy efficiency with reduced current consumption, state-of-art current sense accuracy, and faster switching/slew rate with no impact on EMC, making it suitable for resistive, inductive, and capacitive loads, replacement of electromechanical relays, fuses, and discrete circuits, and many more.
The PROFET -10A Click Board™ uses three digital pins for direct control. The input pin marked as IN routed to the PWM pin of the mikroBUS™ socket activates the corresponding output channel labeled VOUT. Also, the Diagnosis Enable (DEN) pin routed to the CS pin of the mikroBUS™ socket controls the diagnosis and protection circuitry, and in combination with IN pins, it enables the selection of appropriate operating states: Sleep, Stand-by, and Active Mode.
The BTS7008-1EPA is protected against overtemperature, overload, reverse power supply (GND and VIN are reverse supplied), and overvoltage. Overtemperature and overload protection work when the device is not in Sleep mode, while overvoltage protection works in all operation modes. For diagnosis purposes, the BTS7008-1EPA provides a combination of digital and analog signals at the AN pin of the mikroBUS™ socket.
The PROFET -10A Click Board™ supports an external power supply for the BTS7008-1EPA, which can be connected to the input terminal labeled as VIN and should be within the range of 6V to 18V. VIN has an undervoltage detection circuit, which prevents the activation of the power output stages and diagnosis if the applied voltage is below the undervoltage threshold. A power supply indication, red LED labeled as VIN, indicates the presence of an external power supply.
The PROFET -10A Click Board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before use with MCUs with different logic levels. However, the Click board™ comes equipped with a library containing functions and an example code that can be used, as a reference, for further development.

Example Description
This example showcases the ability of the PROFET -10A Click Board™. It configures Host MCU for communication and then enables and disables output channel. Besides that, it reads the voltage of IS pin and calculates current on output.

{
static uint8_t mode = PROFET_DIAGNOSTIC_ON;
float profet_an_voltage = 0;
profet_set_mode( &profet, mode );
if ( PROFET_DIAGNOSTIC_ON == profet.mode )
{
mode = PROFET_MODE_OFF;
log_printf( &logger, " > Output ON diagnostic modern" );

log_printf( &logger, " > Output OFFrn" );
}
if ( profet_read_an_pin_voltage ( &profet, &profet_an_voltage ) != ADC_ERROR )
{
log_printf( &logger, " > IS Voltage t~ %.3f[V]rn", profet_an_voltage );
float current = profet_an_voltage * profet.kilis / profet.rsens;

Additional notes and informations
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 PROFET -10A 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.
