The maximum voltage that can be applied to the VM pin is 40V, but it's recommended to keep it below 36V for reliable operation.
The current limit on the DRV8804PWPR can be adjusted by changing the value of the sense resistor (Rs) connected to the CS pin. A smaller Rs value will result in a higher current limit.
The EN (enable) pin is used to enable or disable the driver. When EN is high, the driver is enabled, and when EN is low, the driver is disabled. This pin can be used to implement a shutdown or standby mode in the system.
The DRV8804PWPR has a built-in thermal shutdown feature that turns off the driver when the junction temperature exceeds 150°C. However, it's recommended to implement external thermal protection measures, such as a thermal sensor or a thermostat, to prevent overheating.
The minimum input voltage required for the DRV8804PWPR to operate is 8V, but it's recommended to use a minimum of 10V for reliable operation.
