![]() ![]() 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). charge pump, enabling minimum energy consump. this card will works in all other aspects, such as controlling the drive. The Cortex-M4, DMA Controller, and peripherals (not peripherals in the low frequency clock domain) run on. When the Charge Pump is removed all outputs on the PMDX-126 are also disabled which means DB25-Pin1 that is set as Enable1 output also vanishes. Stop MACH and the Charge Pump vanishes and again Power goes away. ![]() It integrates the DRV8876 motor driver chip,which supports 9-24V/DC voltage input(The inline DC/DC circuit supplies power to the whole device,the ADC pin G33 is directly connected to the voltage divider circuit and can monitor the power input at any time) The current output is 1.5A, max 2A, It can be used for DC motor speed regulation and forward and reverse control. to EPP mode which Gecko G540 needs for the Charge pump feature to work. Loose Charge Pump or open the ESTOP circuit and all power that could move something is removed. ATOM HDriver is a H-bridge motor driver accessory for M5Atom.
