DRV8800RTYT datasheet by Texas Instruments

DRV8800RTYT Frequently Asked Questions (FAQs)

• What is the maximum voltage that can be applied to the VM pin?
  The maximum voltage that can be applied to the VM pin is 50V, but it's recommended to keep it below 40V for reliable operation.
• How do I adjust the current limit on the DRV8800RTYT?
  The current limit on the DRV8800RTYT can be adjusted by changing the value of the sense resistor (Rs) connected between the IS pin and ground. A smaller Rs value will result in a higher current limit.
• What is the purpose of the EN pin, and how do I use it?
  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.
• How do I protect the DRV8800RTYT from over-temperature?
  The DRV8800RTYT has a built-in thermal shutdown feature that turns off the driver when the junction temperature exceeds 170°C. However, it's recommended to implement external thermal protection measures, such as a thermal sensor or a heat sink, to prevent overheating.
• What is the minimum input voltage required for the DRV8800RTYT to operate?
  The minimum input voltage required for the DRV8800RTYT to operate is 8V, but it's recommended to use a minimum of 10V for reliable operation.
