Logic Inputs (IN1-IN4): The input pins are logic-level signals that control the respective outputs (OUT1-OUT4). They generally receive a signal from a microcontroller or other control circuitry. Power Outputs (OUT1-OUT4): These pins are used to drive external devices like relays, motors, or LEDs. The outputs are capable of handling high-side current (i.e., sourcing current to the load). Ground Pins (GND, PGND): Ground pins are essential for completing the circuit. PGND is the power ground that connects the output current return path, while GND is used for the internal circuit logic ground. Fault Output (FAULT): This pin will output a low signal (typically) when there is a malfunction in the driver IC, such as an overcurrent or thermal shutdown. It provides diagnostic feedback to the system. Enable (EN): The enable pin activates or deactivates the entire device. When driven high, the device is active; when driven low, it enters a shutdown or idle state. Reset (RESET): Used to reset the internal logic and return the IC to its default operational state.Frequently Asked Questions (FAQ)
