BQ24450 三极管损坏问题

Other Parts Discussed in Thread: BQ24450

各位好:

       现在有一款BQ24450的产品在生产过程中出现三极管MJD32CT4 损坏现象。

       现我测试条件:        -没有VIN(不插入16V)              13V电池连接    

        我测量mjd32ct4发射极和基极电压测量。              -发射极电压= 0v              基极电压= 6.7v(这是drvc的bq24450相同的位置)          

        我想问:1.BQ24450的Pin16的工作电压是多少;(我目前测出来为6.7V)

                   2.我选择的三极管MJC32CT4合理吗。(Veb为5v)
