PROFET -15A Click Board™

How Does The PROFET -15A Click Board™ Work?

The PROFET -15A Click Board™ as its foundation uses the BTS70041EPPXUMA1, a single-channel, smart high-side power switch with embedded protection and diagnosis feature from Infineon Technologies. The BTS70041EPPXUMA1 has a driving capability suitable for 15A 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 -15A 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 labelled 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 BTS70041EPPXUMA1 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 BTS70041EPPXUMA1 provides a combination of digital and analogue signals at the AN pin of the mikroBUS™ socket.

The PROFET -15A Click Board™ supports an external power supply for the BTS70041EPPXUMA1, which can be connected to the input terminal labelled as VIN and should be within the range of 4.1V to 28V. VIN has an under-voltage detection circuit, which prevents the activation of the power output stages and diagnosis if the applied voltage is below the under-voltage threshold. A power supply indication, red LED labelled as VIN, indicates the presence of an external power supply.

The PROFET -15A 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.
