Description

A

Block Diagram of DRV81545.

B

OUT1 Channel control parameters.

  • IN1 Duty Cycle: The IN1 PWM duty cycle is adjustable from 0% to 100%.

  • IN1 Frequency: The IN1 PWM frequency can be varied between 0 Hz and 250 kHz, with selectable units (Hz or kHz).

  • IN1 Ramp Rate: ItControls the rate of duty cycle increment.

  • OUT1 Enable/Disable: This toggle switch governs the application of the IN1 PWM signal.

    • Enabled: The IN1 PWM signal is applied to the IN1 pin.

    • Disabled: The IN1 PWM signal is not applied to the IN1 pin.

C

  • Device: Device name
  • Firmware Version: EVM firmware version
  • VM voltage: supply voltage value

D

  • nFAULT Pin Status:

    • Green: Indicates normal operation with no active fault conditions.

    • Red: : Indicates that either over-current or over-temperature protection has been activated for one or more channels.
