PRODUCTION DATA
Figure 9-25 shows the waveform for a positive voltage transition. The timing and voltages apply to both a transition from 0 V to PP_5V0 and a transition from PP_5V0 to PP_HV as well as a transition from PP_5V0 to an PP_EXT. A transition from PP_HV to PP_EXT is possible and vice versa, but does not necessarily follow the constraints in Figure 9-25. When a switch is closed to transition the voltage, a maximum slew-rate of SRPOS occurs on the transition. The voltage ramp will remain monotonic until the voltage reaches VSRCVALID within the final voltage. The voltage may overshoot the new voltage by VSRCVALID. After time TSTABLE from the start of the transition, the voltage will fall to within VSRCNEW of the new voltage. During the time TSTABLE, the voltage may fall below the new voltage, but will remain within VSRCNEW of this voltage.
Figure 9-26 shows the waveform for a negative voltage transition. The timing and voltages apply to both a transition from PP_HV to PP_5V0 and a transition from PP_5V0 to 0V as well as a transition from PP_EXT to PP_5V0. A transition from PP_HV to PP_EXT is possible and vice versa, but does not necessarily follow the constraints in Figure 9-26. When a switch is closed to transition the voltage, a maximum slew-rate of SRNEG occurs on the transition. The voltage ramp will remain monotonic until the voltage reaches TOLTRANUN within the final voltage. The voltage may overshoot the new voltage by TOLTRANLN. After time TSTABLE from the start of the transition, the voltage will fall to within VSRCNEW of the new voltage. During the time TSTABLE, the voltage may fall below the new voltage, but will remain within VSRCNEW of this voltage.
