6. Function Description

Low power lock out and activation

The first time IP5328P access to the battery, whatever the battery voltage, IC is in lock out state, battery level

indicator LED will flash four times; Under non-charging state, if the battery voltage is too low to trigger the low

power shutdown, IP5328P will enter lock out state too.

Under the lock out state, to decrease the quiescent power, IP5328P do not support plug in detect function or

key press activation function. During which, key press action will not trigger boost output, and battery level

indicator LED will flash four times.

Under the lock out state, only by entering charging status can activate IP5328P’s full function.
