    Hello Yu-Sheng Liao,
    Thanks for your interest in TI power blocks.

    CSD87351Q5D: Dual NMOS power block in a half bridge configuration for synchronous buck converter. TI does not spec rds(on) for the FETs in the datasheet. Please see figures 30 & 31 in the datasheet. From these, you can use 7.4mOhm (typical) @ 4.5VGS for the high side and 2.6mOhm (typical) @ 4.5VGS for the low side. This device has passed 400V HBD and 2kV CDM for ESD.

    CSD87350Q5D: Dual NMOS power block in a half bridge configuration for synchronous buck converter. TI does not spec rds(on) for the FETs in the datasheet. Please see figures 30 & 31 in the datasheet. From these, you can use 5mOhm (typical) @ 4.5VGS for the high side and 2.1mOhm (typical) @ 4.5VGS for the low side. This device has passed 500V HBD and 2kV CDM for ESD.
