3. Description
GXM8236 is an integrated motor driver with four N-channel power transistors, a charge pump regulator circuit, and a protection circuit. The charge pump integrates capacitors to reduce the size of the charge pump solution on the PCB.  
GXM8236 has an integrated current regulation function, which is based on the analog input VREF and the voltage of the ISEN pin (proportional to the current flowing through the external resistor). This device can limit the current to a certain level, significantly reducing power consumption.  
GXM8236 provides comprehensive protection against faults and short circuits, including undervoltage lockout (UVLO), overcurrent protection (OCP), and overheat protection (TSD). After troubleshooting, the chip will automatically resume normal operation.
