Part Number: CSD16407Q5

Hi Expert,

The customer sees the CSD16407Q5 is damage on their applicant.

The user case is Oring-Fet of power supply .

The engineer need TI to confirm the question below:

  1. Pls check whether CSD16407Q5 is capable to sustain the turn on loss from the waveform. Pls advice CSD16407Q5 rating can support the switching energy or not.

    Red:Vgs   Blue:Vds   Green: Ids

2. Second question from the waveform.Whether the Mos is fully on during the Vgs raise to 2 ~ 2.5V?Since the current might go through the body diode for the Oring- FET applicant if the Mos not turn on ? How we know the IDS is coming from the body diode or not?

3.If the MOS stayed at the high temperature. The customer ask the rds still become lower than room temperature specified during vgs raise to 2 ~ 2.5V now.

Best regards,

Eric Lai
