Sequencing (SS/TR)
Many of the common power supply sequencing methods can be implemented using the SS/TR, INH and
PWRGD pins. The sequential method is illustrated in Figure 29 using two TPS84210 devices. The PWRGD pin
of the first device is coupled to the INH pin of the second device which enables the second power supply once
the primary supply reaches regulation. Do not place a pull-up resistor on PWRGD in this configuration. Figure 30
shows sequential turn-on waveforms of two TPS84210 devices.

Simultaneous power supply sequencing can be implemented by connecting the resistor network of R1 and R2
shown in Figure 31 to the output of the power supply that needs to be tracked or to another voltage reference
source. Figure 32 shows simultaneous turn-on waveforms of two TPS84210 devices. Use Equation 3 and
Equation 4 to calculate the values of R1 and R2.
