7.3.5 Power Sequencing and VR Control

When a valid power source is available at VSYS (VSYS ≥ 5.6 V), internal analog blocks including LDO5 and LDO3P3 are enabled. For part numbers with LDOA1 set as an always on rail, the PMIC leaves reset and I2C communication is available as soon as LDO3P3 and LDO5 power goods are confirmed. For part numbers with LDOA1 set as a general-purpose LDO, the PMIC remains in reset until PMICEN is set high. Five input pins of the TPS65094x device are driven by a host or by external-controller (EC) defined power states that transition from one to another in sequence.

Table 7-8 shows various system-level power states. Also, Table 7-9 summarizes a list of active rails in each power state. The sequencing for the transitions between these states is described in the following sections.

If a rail is either disabled by I2C or OTP programming, then it is not enabled by the following sequences. For example, VTT LDO is not enabled for LPDDR4 OTPs.

Table 7-8 Power State and Corresponding I/O Status
POWER STATE SIGNALS TO PMIC SIGNALS FROM PMIC
PMICEN SLP_S4B(1) SLP_S3B(1) SLP_S0B(2) THERMTRIPB(3) RSMRSTB PCH_PWROK
G3 0 0 0 0 0 0 0
S4/S5 1 0 0 1 1 1 0
S3 1 1 0 1 1 1 0
S0iX 1 1 1 0 1 1 1
S0 1 1 1 1 1 1 1
(1) When PMIC is first enabled, SLP_S4B and SLP_S3B are to be treated as if they are low (actual state of signal ignored) until the deassertion of RSMRSTB (L → H).
(2) When PMIC is first enabled, SLP_S0B are to be treated as if they are high (actual state of signal ignored) until the assertion of PCH_PWROK (L → H).
(3) THERMTRIPB is to be treated as if it is high (actual state of signal ignored) until the deassertion of RSMRSTB (L → H).
