Datasheet

7. Functional Description

7.1. Power

The ALC5624 has many power blocks. SPKVDD operates between 2.3V and 5V. HPVDD, AVDD2, and

AVDD1 operate between 2.3V and 3.6V. DVDD1 and DVDD2 operate between 1.8V and 3.6V. The

power supply limit condition are DVDD1≥DVDD2, SPKVDD≥AVDD1=AVDD2, HPVDD≥AVDD1=

AVDD2≥DVDD2.

7.2.1. Power-On Reset (POR)

When powered on, DVDD2 passes through the VPOR band of the ALC5624 (VPOR_ON ~VPOR_OFF). A

Power-On Reset (POR) will generate an internal reset signal (POR reset ‘LOW’) to reset the whole chip.
