WARNING!
We recommend to add a regulator voltage for an external current greater than or equal to 600 mA, in those applications where the
operating temperature range is important.
NOTE: Engicam not provide for a dissipation system, it is customer's own responsibility to evaluate the appropriate heatsink
and the dissipation system depending of its own application.
For further details on the power supply please refer to "i.MX 6UL" Data Sheet and Reference Manual.
5.2.1 How to connect a backup battery
The module allows the use of lithium rechargeable battery or supercapacitor as backup battery.
The connection with module is obtained by connecting directly the backup battery to the +Vcoin signal (pin 18 floating if not used).
The consumption of the pin is given by NXP for a maximum of 300uA
Note:
The maximum VDD_SNVS_IN current may be higher depending on specific operating configurations, such as
BOOT_MODE[1:0] not equal to 00, or use of the Tamper feature. During initial power on, VDD_SNVS_IN can draw up to 1
mA, if available. VDD_SNVS_CAP charge time will increase if less than 1 mA is available.
Note:
The module is already designed to manage the charge of backup battery.
For further details on the power supply please refer to "i.MX 6UL" Data Sheet and Reference Manual.
