DRV8801PWP datasheet by Texas Instruments

DRV8801PWP 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 DRV8801PWP?
  The current limit on the DRV8801PWP can be adjusted by changing the value of the sense resistor (Rs) connected between the SENSE pin and GND. 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 DRV8801PWP from back-EMF when using inductive loads?
  To protect the DRV8801PWP from back-EMF when using inductive loads, a freewheeling diode (D1) should be connected in parallel with the load. This diode provides a path for the back-EMF current to flow when the driver is turned off.
• What is the maximum frequency that the DRV8801PWP can operate at?
  The DRV8801PWP can operate at frequencies up to 100 kHz, but the maximum frequency may be limited by the specific application and the type of load being driven.
