Darren Jenkins

Hello Battery Management team,

Which reference design should a customer work from to create a boost output for their system to run at 5.5V? (Or something similar)

Thanks,

Darren

Hello Darren,

The EVM design information is a good starting point for the component setup: https://www.ti.com/tool/TIDA-00589

To enable boost mode the host must set the BOOST_CONFIG, which is enabled by default.

Sincerely,

Hello Dipak,

Can you explain the situation in more detail? Are you referring to if the charger is in OTG mode and a VBUS of 6V is connected? Or if OTG is enabled while VBUS is present?

Can you explain your test scenario.

Sincerely,

Wyatt Keller
