TIDA-00489: Maximum input voltage and use of 3.6V Lithium Batteries

Part Number: TIDA-00489

What is the maximum input voltage for the TIDA-00489?

To expand the lifetime at higher current consumptions, I want to change the coin cell holder with a regular AA-Battery holder and supply the device by a 3.6V Lithium Battery (Type Saft LS14500).

Is this possible without damaging the device over time?

If yes, what could be other effects to the device? Higher current consupteion compared to a 3V coin cell supply?

Best regards and thanks for you answeres!

  • The maximum voltage for TIDA-00489 is 3.8V which is determined by the microcontroller.  Supplying this design with 3.6V should not be a problem other than slightly higher supply current as you mentioned.  Table 3 of the design guide will give you an indication of how much increase in supply current you can expect.

    Regards,
