(Note 1) The DVDD Voltage must be under the Battery voltage VBAT, PBAT anytimes.
(Note 2) This is an allowable loss of the ROHM evaluation board (54mm×62mm). .When a substrate is implemented, the allowable loss varies from the size and material
of the substrate. Derate 1% per °C for temperatures higher than 25°C.
Caution:
Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit between
pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated over the absolute
maximum ratings.

(Note 3) Whenever VBAT, PBAT, VIN1, or VIN2 falls below the LDO or SWREG output voltage, or below certain levels, LDO and SWREG output is not guaranteed to
meet the published specifications. It is necessary to supply the same voltage to VBAT and PBAT.
(Note 4) It is recommended to connect SWREG5 output to VIN1 to maximize efficiency.
(Note 5) It is recommended to connect SWREG4 output to VIN2 to maximize efficiency.
