VDDQ, VTT and VTTREF turn-off (soft end)
10.7.1
Tracking discharge
The JP2 jumper, if placed in the middle, allows the output tracking to be discharged. When
S3 and S5 are pulled down, VTT discharges VDDQ by sinking 1 A and, at the same time,
tracks the VDDQ half. When VDDQ reaches approximately 400 mV, the output discharge
MOSFETs are all closed and each rail is finally discharged.
Figure 29.

tracking discharge, no load on any rail
10.7.2
Non-tracking discharge
When the non-tracking discharge is programmed (JP2 in the lower position) and S3-S5 are
both tied to GND, each output rail is discharged through its discharge MOSFET, as depicted
in Figure 30.
