BQ25616: BQ25616 BATFET turn off issue

Star,

What were the BAT pin voltage before and after the LED light of the portable device is turned on? How much was the battery discharge current?

Thanks,

Ning.

Hi Ning T

Thanks for your reply.

The BAT pin voltage before lighting is 3.4V, after lighting the voltage is about 2.66V. Battery discharge current is 5A when the lamp is on.

When the lamp is off the discharge current is 1.5A. The light will turn on for 2ms and turn off for 3ms, repeatedly switching on and off.

Waiting for your reply.

Thanks

Star

Star,

Was a real battery or battery simulator used for the tests?

Thanks,

Ning.

Hi Ning 

Thanks for your reply.

They use the real battery, Lithium-ion battery.

Thanks

Star

Star,

What's the battery terminate voltage when the BAT pin voltage is 2.66V after lighting?

Thanks,

Ning.

Hi Ning

The battery terminate voltage is 2.3V.

Thanks

Star

Star,

Are you talking about battery discharging at 5A? If so, how can the battery terminal voltage (2.3V) be lower than the BAT pin voltage (2.66V)?

Thanks,

Ning.
