25 / 40 page  AN2808 PM6670S evaluation tests 25/40 10.7 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. VDDQ, VTTREF, VTT output voltages and LDO input current, 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. |
