Product information "M5Stack ATOM H-Bridge Driver Kit (DRV8876)"

ATOM HDriver is an H-bridge motor driver accessory for M5Atom. It contains 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 current input at any time). The current output is 1.5A, max 2A, it can be used for speed control of DC motors and forward and reverse control. The driver contains an N-channel H-bridge, a charge pump controller, current detection and control, a current proportional output and a protection circuit (protection functions: Undervoltage cut-off of the power supply (UVLO), undervoltage of the charge pump (CPUV), overvoltage current at the output (OCP) and overtemperature of the device (TSD), error states are also displayed via the FAULT pin).
