PRODUCTION DATA
If active, the REG_TMR will monitor the time a VOUTx takes to cross the VONx voltage once the ENx signal is forced high. In the case the REG_TMR is expired and VOUTx has not crossed the VONx voltage, a reverse sequence down from the previously sequenced rail will be started as described in the State Machine section. Figure 8-8 shows the REG_TMR active during sequence up, from the time ENx is forced high (VOUTx starts rising). In this case, VOUTx always crosses VON before the timer is expired. The REG_TMR resistor can be selected using Equation 16. Figure 8-10 shows the linear trend between the REG_TMR resistor and the regulation time allowed for the rail to be in regulation (VOUTx > VONx).
Table 8-2 shows typical resistor values for different allowed regulation times.
