BQ24192: Simulation the situation of thermal performance of bq24192

Part Number: BQ24192

Hi team,

My customer is using our bq24192 for their battery charger design and they are testing thermal performance of the charger IC. Therefore, they need to connect a constant current at the load for few hours.

But they are not sure how to to do it by electrical load since there is no current flow through  pin BAT of charger IC .

Could you kindly guide us how to do this test? Is there any setting that customer should set (such as constant current value) at charger?  Thank for your kindly help.

    Hi,

    It is ok to connect the electrical load to SYS pin without the battery. If battery charging is preferred, it is ok to use bi-directional power supply as battery simulator (e.g. Keithley 2420 sourcemeter).

    Thanks,
