What are the differences between the old HL6528 and HL6528RD?
We had to redesign the power supply section after we found that the VBATT/VBATT_PA is now maximum 4.3V only.
Previously it was 4.5V. Out power supply PMIC produces 4.4V maximum.
Other than this, what are the other differences?
And why introduces a new variant?
