BQ51025: BQ51025

Part Number: BQ51025

Hi,

I need to confirm if the root for failing of many BQ51025YFPR (burnt), could be because the Input AC voltage on AC1 - AC2 input pines are more than 20Volts Pk to Pk, according the attached Oscilloscope picture. That is the wave received from a coil on(pines AC1 & AC2).

The fail in the device are not instantaneous and occur after some elapsed time (more than one months, average).

According the datasheet, the maximum voltage rate between AC1-AC2 is 20 Volts; I suppose that is Pk to Pk but I'm not sure.

Thanks.
