53 / 101 page  DA9062 PMIC for Applications Requiring up to 8.5 A Datasheet Revision 3.8 15-Feb-2022 CFR0011-120-00 53 of 99 © 2022 Renesas Electronics Table 30: Regulator Control Functionality of the Power Supply Sequencer Power-Up (Sequencer Direction Up) Auto Conf POWERDOWN Mode (Before) ACTIVE Mode (After) En Sel En Sel Sequencer Functionality 0 0 x x 0 0 The regulator is disabled at the step pointed to by BUCK<x>_STEP/LDO<x>_STEP and the A-setting (VBUCK<x>_A/VLDO<x>_A) is activated. x 1 x x 1 0 The regulator is enabled at the step pointed to by BUCK<x>_STEP/LDO<x>_STEP and the A-setting (VBUCK<x>_A/VLDO<x>_A) is activated. 1 x x x 1 0 Power-Down (Sequencer Direction Down) Auto Conf ACTIVE Mode (Before) POWERDOWN Mode (After) En Sel En Sel x 0 x x 0 0 The regulator is disabled at the step pointed to by BUCK<x>_STEP/LDO<x>_STEP and the A-setting (VBUCK<x>_A/VLDO<x>_A) is activated. x 1 x x 1 1 The regulator stays enabled but it is switched to the B-setting (VBUCK<x>_B/VLDO<x>_B). Step 0 of the sequencer has a special meaning. If register DEF_SUPPLY is set, the sequencer treats all regulators pointing to step 0 as default supplies. This means that the regulators are enabled automatically when entering the POWERDOWN mode. Regulators assigned to other steps are only enabled after a wakeup condition occurs. Apart from this, step 0 acts the same as steps 1 to 15. If register DEF_SUPPLY = 0, step 0 of the sequencer does not have any affect. As mentioned in Section 8.6.1, LDO1 can be programmed as an always-on supply. This is achieved by setting controls DEF_SUPPLY, LDO1_CONF, and LDO1_EN in the OTP. In normal operation, when the sequencer moves between ACTIVE and POWERDOWN modes, LDO1 behaves as presented in Table 30. However, if DA9062 moves to the RESET mode, this configuration keeps LDO1 enabled. This is not the case for any other regulator. 8.9.4 GPO Control Any GPO can be asserted or de-asserted in a sequencer step (GP_RISE<x>_STEP, GP_FALL<x>_STEP). The GPO control is summarized in Table 31. If a GPO is controlled by the sequencer, it is driven to its inactive state when DA9062 is in RESET mode. The GPIO control only works in sequencer steps greater than zero. Table 31: GPO Control Functionality of the Power Supply Sequencer GPIO<x>_MODE GPO State After Reset Sequencer Direction Previous GPO State GPO Transition At GP_RISE<x> GPO Transition At GP_FALL<x> 0 (active low) High Up High High to low - Low - Low to high Down High - High to low Low Low to high - 1 (active high) Low Up High - High to low Low Low to high - Down High High to low - Low - Low to high |
