Functional description

Figure 24. Zoomed waveform
The VBIAS pin absolute maximum ratings (see Table 2: Absolute maximum ratings on
page 6) must be satisfied over the different dynamic conditions.
If VBIAS is connected to GND there are no issues (see Figure 23 and Figure 24).
A small resistor value (few
) in series with the VBIAS can help to limit the pin negative
voltage (see Figure 25) during heavy short-circuit events if it is connected to the regulated
output voltage.
