Description

Atomic HDriver Base is an H-bridge motor driver compatible with the Atom series controllers. It features a built-in DRV8876 motor driver chip that supports DC 9~24V power input. An integrated DC/DC circuit powers the entire device, while the ADC pin G33 is connected directly to a voltage divider circuit for real-time monitoring of the input power supply. The output current reaches 1.5A with a peak capacity of 2A, making it suitable for DC motor speed control and forward/reverse rotation control. The driver integrates an N-channel H-bridge, charge pump voltage regulator, current sensing and regulation, current ratio output, and protection circuits. Protection features include undervoltage lockout (UVLO), charge pump undervoltage (CPUV), output overcurrent protection (OCP), and thermal shutdown (TSD), with fault conditions indicated via the FAULT pin.
