Atomic HDriver Base is an H-bridge motor driver compatible with the ATOM series controllers. It features the DRV8876 motor driver chip, supports DC 9 ~ 24V power input (with an embedded DC/DC circuit to power the entire device, and the ADC pin G33 is directly connected to a voltage divider circuit to monitor the power input in real-time), and can output up to 1.5A, with a peak of 2A, suitable for DC motor speed control and forward/reverse control. The driver integrates an N-channel H-bridge, charge pump regulator, current sensing and regulation, current proportional output, and protection circuits (with integrated protection features: undervoltage lockout (UVLO), charge pump undervoltage (CPUV), output overcurrent (OCP), and device overtemperature (TSD), with fault conditions indicated via the FAULT pin).
