Conclusion

With the increase in larger applications using rechargeable batteries, it is now possible to design applications that:

  • Support input power for the USB PD EPR standard.
  • Optimize the charging and discharging of multicell battery applications with USB Type-C.
  • Facilitate solar compatibility for on-demand charging from anywhere.

The convenience of using the same USB Type-C port and the new USB PD EPR enable larger battery devices such as vacuums, e-bikes and power banks to charge with USB Type-C In addition, having a bidirectional power flow charger allows battery pack charging and discharging from the same USB Type-C port. This functionality can turn any battery pack into a power bank. Finally, a battery charger that can take solar panel input and MPPT enables applications that consumers can charge from anywhere.

The BQ25756 – combined with a TI PD controller such as the TPS25750 – can help you design diversified rechargeable battery applications. The advanced MPPT algorithm in the BQ25756 finds the MPP for solar panels based on current light levels to help optimize the solar charging experience.
