Tool/software:
Hello,
We have recently experienced an issue where Pin 22 (BTST) of the TI Charger BQ24610RGT was burnt.
Currently, our charging condition is 24 V, 3.8 A, and the battery operates at 15–20.5 V.
The failure condition seems to be that when charging suddenly does not occur for some reason, the BTST pin gets burnt.
Please find attached the partial circuit around BTST and the burnt area for your reference.
We would like to ask if there are possible scenarios where such a failure could occur, and if there are any recommended countermeasures for this issue.
Since this is confidential, please also let us know the route through which we can receive the schematics and artwork that can be shared externally. This product is scheduled for mass production in September.
Please help me ASAP
Best regards,
