3.3.1 Power Up

  1. Before beginning the power up test procedure, verify the connections with Figure 4-1.
  2. Enable supply #1, if the current on DMM1 is more than 0.05 mA and less than 0.3 mA, everything is set correctly.
  3. Turn on Channel A of function generator.
  4. The following behavior should be observed:
    1. Stable pulse output on channel-1 and channel-2 of the oscilloscope, refer to Figure 4-2.
    2. Frequency measurement is 100 kHz, ±5 kHz or equal to the programmed function generator frequency.
    3. DMM #1 displays around 2.9 mA, ±0.75 mA with the default load capacitance of 1.8 nF. For more information about operating current, see the UCC27332Q1 Single Channel 20 V 9 A High Speed Low Side Gate Driver Data Sheet.
