Dear expert:
We used TPS2116 to design as follows, using automatic mode, giving priority to 3.0V power supply of VIN 1 pin dry battery, followed by 3.7V power supply of VIN 2 pin lithium battery, but we found a problem, when both kinds of batteries are connected (there are 3.7V lithium battery and 3.0V dry battery, currently 3.0V dry battery is re-powered, However, when the single battery is unplugged, the system will lose power and can not be quickly switched to 3.7V lithium battery power supply), please help to see, TPS2116 should be able to meet this demand? (Unplug one of the electricity, can not lose power, the other power quickly supply, see the specification is able to meet) and then help to see the circuit about the design of TPS2116 is there a problem? Thanks, schematic diagram below:
