DRV8832QDGQQ1 datasheet by Texas Instruments

DRV8832QDGQQ1 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 18V, but it's recommended to keep it below 15V for reliable operation.
• How do I properly sequence the enable pins (ENx) and input pins (INx) during startup?
  It's recommended to sequence the enable pins (ENx) high before applying the input signals (INx) to prevent unwanted motor movement during startup.
• What is the recommended decoupling capacitor value for the VM pin?
  A 10uF to 22uF ceramic capacitor is recommended for decoupling the VM pin to ensure stable operation and reduce noise.
• Can I use the DRV8832QDGQQ1 with a brushed DC motor?
  Yes, the DRV8832QDGQQ1 can be used with brushed DC motors, but it's primarily designed for stepper motors and may not provide optimal performance with brushed DC motors.
• How do I calculate the current sense resistor (RSENSE) value for my specific application?
  The RSENSE value depends on the motor current and desired sense voltage. A general guideline is to choose a RSENSE value that sets the sense voltage to around 50mV to 100mV at the maximum motor current.
