TPS6594x-Q1 Evaluation Module

Figure 6. Header J37, Recommended Power Sequence (Enable) for Master and One or More Slaves

Table 9. Header J37 Master/Slave Select

Configuration

Description

Open

When used as a single PMIC (no stacking). ENABLE is
connected to a pullup and therefore automatically enabled. S1
can be used to generate edges or change the level.

Slave, M/S Select: Closed

Slave Mode. The PMIC signal ENABLE is connected to the
nPWRON_S signal which is from the master's VOUT_LDOVINT.

M/S Select, Master: Closed

Master Mode. The PMIC signal, VOUT_LDOVINT, is connected
to the nPWRON_S which will be the ENABLE signal on the
PMICs connected as slaves.
