Part Number: BQ32000
How to achieve low backup supply current as mentioned in section 8.2.2.3 Utilizing the Backup Supply of the datasheet.
(8.2.2.3. In order for the bq32000 to achieve a low backup supply current as specified in the Electrical Characteristics, the VCC pin must be initialized after every total power loss situation. Initialization Is achieved by powering on VCC with a voltage between 3 to 3.6 V for at least 1 ms immediately after the backup supply is connected. If the VCC is not powered on while connecting the backup supply, then the expected leakage current from VBACK will be much greater than specified.)
Is there any application note or reference design available on this concern ?
