Notes
5. Min V
value guarantees that there is a sufficient charge available to complete a successful AutoStore operation. Max V
value guarantees that the capacitor on
CAP
CAP
V
is charged to a minimum voltage during a Power-Up RECALL cycle so that an immediate power-down cycle can complete a successful AutoStore. Therefore it
CAP
is always recommended to use a capacitor within the specified min and max limits. Refer application note AN43593 for more details on V
options.

6. Maximum voltage on V
pin (V
) is provided for guidance when choosing the V
capacitor. The voltage rating of the V capacitor across the operating
