5.1 Timing Diagram Values

The following table lists the timing diagram values of the XIFM gate driver.

Note: Condition VSUP = 24V, Temp. = 0 °C to 85 °C.

Note:
  1. Measured from 50% to 50% of input trigger and output VGS signal.
  2. Measured from 10% to 90% of output VGS signal.
  3. Measured without augmented settings and at no load condition.
  4. Software configurable depends on user requirements.
  5. Hardware blanking time is set to the present value in the table.
  6. Death Time must be configured by the user by the host controller.
  7. This is fault output delay time, but when DSAT is detected on board gate driver shouts-down trigger within 25 ns.
  8. The minimum pulse width is a factor of the multi-level turn-off and two-level turn-on time.
