 ## Description
 
-**ATOM HDriver** is a `H-bridge` motor driver adapted to ATOM controller. Built-in DRV8876 motor driver chip, support `9-24V/DC power input` (Built-in DC/DC circuit powers the whole device, ADC pin G33 direct voltage divider circuit can monitor the power input at any time), the output current can reach `1.5A`, `peak 2A`, can be used for DC motor speed regulation and forward and reverse control. The driver integrates N-channel H bridge, charge pump regulator, current detection and regulation, current proportional output and protection circuit (protection function integration: power supply undervoltage lockout (UVLO), charge pump undervoltage (CPUV), output overvoltage Current (OCP) and device over temperature (TSD), fault conditions are also indicated by the `FAULT` pin).
