The maximum current rating of the DRV8837CDSGT is 2.5A per channel, with a peak current of 4A.
The DRV8837CDSGT can be configured for different motor types by adjusting the input logic levels and the enable pin. For example, for a stepper motor, the input logic levels should be set to 5V, and the enable pin should be tied high. For a DC motor, the input logic levels should be set to 3.3V, and the enable pin should be tied low.
The internal voltage regulator in the DRV8837CDSGT is used to generate a 5V supply for the internal logic and the gate drivers. This allows the device to operate from a single supply voltage, and eliminates the need for an external voltage regulator.
The DRV8837CDSGT has built-in overcurrent protection and thermal shutdown features. The device will automatically shut down if the current exceeds 4A or if the junction temperature exceeds 150°C. Additionally, external protection circuits can be added to provide additional protection against overcurrent and overheating.
The minimum input voltage required for the DRV8837CDSGT is 6.5V, although the recommended operating voltage range is 8V to 35V.
