Working Principle

The working principle of the DRV8884EVM is based on the integrated circuit technology of DRV8884, which is a high-current MOSFET driver. It is designed to drive two application-specific MOSFET banks with a total supply current range of 0. 8A to 8A and output drive capability of 400mA to 2. 2A each. The DRV8884EVM board can be used to adjust the output voltage from 7V to 35V.

The DRV8884EVM board has three input pins which are VBus(input voltage), VDrain(high voltage for MOSFET switching) and ENPIN(input signal connected to ground to enable the circuit). The VDrain is connected to the positive output of the main power supply, while the Vbus is connected to the negative output. ENPIN is connected to a signal which drives the circuit to turn on and off.

When the ENPIN is connected to the ground voltage, the DRV8884 integrated circuit is enabled and drives the MOSFET gates depending on the input signal. The board also has two LED indicators that are connected to the VBus and VDrain lines. When the circuit is enabled, the LED indicator near the VBus pin shows the presence of a low voltage while the LED indicator near the VDrain pin shows the presence of a high voltage, indicating the presence of a working circuit.
