BQ25606: BQ25606RGER pin state in Charging disable mode.

Vitaliy Gurevich

Part Number: BQ25606

Hi,

Could you please advise what the recommended state of the below pins, when the charger is permanently disabled (CE=HIGH), OTG is not used and BQ25606RGER is used in the Supplement Mode with EXT VBUS 5-9V and BAT input voltage 4.4V?

OTG - GND/Open?

VSET- Open/GND/PD? should it be set up to the actual BAT voltage?

ICHG - GND/Open/PD?

Regards

Vitaliy

Vitaliy,

Please visit https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/890626/faq-bq25606-schematic-review-and-pcb-layout-design-tips for BQ25606: Schematic Review and PCB Layout Design Tips. Additional Information including FAQs is available http://www.ti.com/lit/an/slva924/slva924.pdf Designing A Standalone Single Cell 3-A Charger with the bq25606.

For your case, it should be ok to do the following:

OTG-GND

VSET-GND or OPEN

ICHG-Connects to GND via a resistor (e.g. 1100ohm).

Thanks,

Ning.
