BQ24253: Single Li-Ion Battery to be charged

Atul Bhakay

Part Number: BQ24253
Other Parts Discussed in Thread: BQ25896, BQ24650

Dear Sir,

We are developing the new solar system base Gas Detectors. We need suitable TI IC which can fulfill our application of gas detection..

Application:

System needs 20 milli Amp continuously and 2 Amp spike for 500 milli sec. There is one Li-ION chargeable Battery (3.7V Li-IoN).

Along with this we are using 30W 12Volt 1.4Amp to 1.7Amp output Solar panel. Please suggest suitable circuit and IC for the same.

Is BQ24253 a suitable part to charge this Li-Ion battery ?

Regards

Hi Atul,

The bq24253 cannot accept a 12-V input voltage. If you have host software available to implement maximum power point detection, you could use bq25896. If no host is available, you might consider the bq24650 and adding the circuit explained in http://www.ti.com/lit/pdf/slua586, after characterizing your solar panel.
