Notes
19. Min V
CAP
value guarantees that there is a sufficient charge available to complete a successful AutoStore operation. Max V
CAP
value guarantees that the capacitor on
V
CAP
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
is always recommended to use a capacitor within the specified min and max limits. Refer application note AN43593 for more details on V
CAP
options.
20. Maximum voltage on V
CAP
pin (V
VCAP
) is provided for guidance when choosing the V
CAP
capacitor. The voltage rating of the V
CAP
capacitor across the operating
temperature range should be higher than the V
VCAP
voltage.
21. These parameters are guaranteed by design and are not tested.
