nPM2100 + Li/FeS2 ship mode

Hello everyone,

We are currently working on a project in which we plan to use the nPM2100 + NRF powered by two AAA Li/FeS2 batteries.

We would like to use the nPM2100 ship-mode feature - the batteries would be connected to the circuit during shipment to the customer, and the device would only start operating after being taken out of the packaging (reed switch). However, we are wondering about regulations regarding shipping devices like this. The user will not have access to the battery holder/compartment (we expect the device to operate for about 5 years and then be replaced), so there is no way to physically disconnect the batteries.

From what we have found so far, devices of this type with batteries can be shipped even without special marking due to the low lithium content (<1 g per battery), provided they are properly protected against short circuits and accidental activation, plus if requested a UN38.3 declaration from the battery manufacturer.

Has anyone shipped devices using this type of battery and can confirm whether ship mode is sufficient protection against the device turning on during transport from a regulatory standpoint?

Best regards,

Paweł

  • Hi Pawel,

    The nPM2100 ship mode is an appropriate method for preventing accidental activation during transport, as the ship mode disables the system rails and ensure the device remains in an ultra-low power state.

    However, regulatory compliance for shipping lithium metal batteries (such as Li/FeS₂) is determined by transport regulations (e.g., UN3091 – lithium metal batteries contained in equipment), not by the PMIC implementation itself. So final compliance assessment should be confirmed with your battery supplier and shipping provider.
