BQ76200 高侧驱动问题

Other Parts Discussed in Thread: BQ76200

您好,现在我用BQ76200做了锂电管理系统 NMOS的高侧驱动, 部分原理图如下,使能端全部接到MCU ,并且全部置高(3.3V),但是输出端CHG(16pin)任然为BAT_T+ 电池组总电压53V,DSG(12PIN) 为10V左右,   PCHG 是40V(这个是PMOS驱动,看来是这个是对的), 当时以为是我的MOS端影响到了输出,后来去掉了R194,R201,R202,现象还是一样, 测量VDDCP(PIN1) 60V, BAT 电压53V(2PIN),  后面D58也去掉了,但是现象还是一样,请帮我分析一下问题出在哪里呢?
