Design considerations
- Typically, remote controls use one or two AA / AAA batteries, but they can also utilize a LiPo battery or even coin cells.
- Systems typically have a USB-C connector as back up charging option
- Designs can include an embedded microphone to manage voice commands and an optional LCD display
- The IR circuity can be external although some SoCs have a built in LED drive transistor

Adaptive energy harvesting PMIC enables environmentally friendly autonomous, connected devices
Ambient energy harvesting has often been proposed for recharging batteries in remote internet-of-things devices but hasn’t yet taken off. Nexperia's new dedicated PMIC is set to radically improve the viability of energy harvesting with significant benefits for the environment.ve energy harvesting PMIC enables environmentally friendly autonomous, connected devices
