Other Parts Discussed in Thread: BQ24210

Hi,

I am using a 6v 200mA solar panel to charge a 3.7v 510mAh Li-Polymer battery, which option will be better:

1. Connecting TS to input

2. Connecting TS to VSTB

I need the PCB layout for Bq24210, can any one help?

Thanks,

Hello Shahbaz,

I would recommend using the TS pin for its intended purpose of monitoring your pack temperature. Li-Polymer is not something to just toy around with and the reason why the TS pin is incorporated into the design is to protect your designs and whoever is using it by monitoring the battery and controlling the charge and discharge to ensure its stays in a safe operating range.

Regarding a PCB layout I would recommend looking at the layout used for the EVM or the one shown in the reference guide Pg. 8-9.
