    PSOC 4 Battery Charging

    JeCr_2235141

      I would prefer to integrate with lithium ion battery. Is there some application note around this kind of integration?

       

      I am currently evaluating MCP73171 from microchip to power lithium ion battery.  Needs to be lithium ion so as to demonstrate some specific IOT projects we are working on.  In PSOC 4 documentation there is reference to coin cell (LiPO4) but I cannot use this approach.  There is also reference to not operating PSOC4 using 5V.  So I am curious if LIthium Ion is compatible (can range between 3.3V and 5V).  I did find this Lithium Ion battery but not sure if it is compatible with MCP yet (waiting to hear from microchip.

      So basic questions:

      • Is there application note i can reference for PSOC4 rechargeable battery integration
      • Is Lithium Ion Battery compatible with PSOC4
      • Is there recommended maximum voltage for PSOC4 battery
      • Is there recommended recharging chip for Lithium Ion battery for PSOC4.

       

      Appreciate any answers to any of these questions.

       

      Thanks

          Hi Jerome,

           

          Is there application note i can reference for PSOC4 rechargeable battery integration

                    There is no application note dedicated for PSoC4 battery charging. We have PSoC 3/5 device Li ion battery charger application note cane be referred where PSoC 5 is used for battery charging application.

           

          • Is Lithium Ion Battery compatible with PSOC4

                    Yes.

          • Is there recommended maximum voltage for PSOC4 battery

                    The absolute maximum VDD for PSoC4 device is 6( which the device can with stand). The device can work voltages below that till 1.8V.

          • Is there recommended recharging chip for Lithium Ion battery for PSOC4.

                    There is no recommended recharging chip. You just have to make sure the ratings specified in the datasheet are met. Do check the absolute maximum ratings and DC specifications.
