Part Number: BQ24133

The customer design with BQ24133 and find the SW output voltage =PVCC, PVCC=13V，SW=13V PVCC=15V，SW=15V

Test as below:

Remove TS resistance, the SW has no output voltage, and the STAT blinks.

ISET voltage 139mV

ACSET voltage 140mV

Attached the schematic:

Please give some suggestions.

Thanks

Dear Star,

What are the conditions? What is the input voltage? Is there a battery voltage? How much voltage is on the battery? What does STAT do before the TS resistance is removed? Please provide a more detailed description of each setup.

Thanks,

Mike Emanuel
