Min VCAP value guarantees that there is a sufficient charge available to complete a successful AutoStore operation. Max VCAP value guarantees that the capacitor on VCAP 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 VCAP options. 18. Maximum voltage on VCAP pin (VVCAP) is provided for guidance when choosing the VCAP capacitor. The voltage rating of the VCAP capacitor across the operating temperature range should be higher than the VVCAP voltage. 19. These parameters are guaranteed by design and are not tested. |
