Bit name and function | HOLD_LDO1 | LDO1_DISCH | LDO1[5] | LDO1[4] | LDO1[3] | LDO1[2] | LDO1[1] | LDO1[0] |
Default except TPS657202 | 0 | 1 | 1 | 0 | 0 | 1 | 0 | 1 |
Default for TPS657202 | 0 | 1 | 1 | 1 | 1 | 0 | 0 | 1 |
Default value loaded by: | UVLO/R | UVLO/R | UVLO/R | UVLO/R | UVLO/R | UVLO/R | UVLO/R | UVLO/R |
Read/write | R/W | R/W | R/W | R/W | R/W | R/W | R/W | R/W |
Bit 7 | HOLD_LDO1:
0 = LDO1 is disabled when HOLD_LDO1 pin is pulled LOW and PB_IN is released HIGH 1 = LDO1 stays enabled when HOLD_LDO1 pin is pulled LOW and PB_IN is released HIGH |
Bit 6 | LDO1_DISCH:
0 = LDO1 output is not discharged when LDO1 is disabled 1 = LDO1 output is discharged when LDO1 is disabled |
Bit 5..0 | LDO1 output voltage setting according to the table listed for DCDC1:
The voltage setting is only valid for TPS65720. For TPS65721, the LDO1 voltage is set by an external resistor-divider. The voltage setting is according to the same table given for DEFDCDC1. |
