BQ25720: THERMAL DATA REQUIREMENT

Pulkit Kumar

Part Number: BQ25720

We are using one Battery charger part ( part no BQ25720RSNR) in our design and we need the thermal data for this part for thermal simulation

Kindly provide the below thermal details for this parts as these values are missing in its datasheet

1. RThetaJA

2. RThetaJB

3. RThetaJC

4..Power Dissipation

Hi Pulkit,

I believe these values are covered in the datasheet, see below for 1-3. You can look at section 8.7 Typical Characteristics for the efficiency at various conditions.

Regards,

Jacob

Hi Udesh,

Please refer to section 8.7 Typical Characteristics of the data sheet to see the efficiency curves. These curves can be used to determine what the power dissipation and consumption should be. I hope this helps.
