HOW DOES IT WORK?
PROFET 2 Click as its foundation uses the BTS70082EPAXUMA1, a dual-channel, smart high-side power switch with embedded protection and diagnosis feature from Infineon Technologies. The BTS70082EPAXUMA1 has a driving capability suitable for 7.5A 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.
This Click board™ uses five digital pins for direct control. The input pins IN0 and IN1, routed to the PWM and INT pins of the mikroBUS™ socket, activate the corresponding output channels labeled VOUT0 and VOUT1. 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 BTS70082EPAXUMA1 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 BTS70082EPAXUMA1 provides a combination of digital and analog signals at the AN pin of the mikroBUS™ socket. Besides, the Diagnosis Selection DSEL pin, routed to the RST pin of the mikroBUS™ socket, selects the channel on which a diagnosis will be performed.
The PROFET 2 Click supports an external power supply for the BTS70082EPAXUMA1, which can be connected to the input terminal labeled as VIN and should be within the range of 4.1V to 28V. 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.
This 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.
