TPS53659: Does "Vin OVP response" setting can be changed?

Part Number: TPS53659

Hi Expert,

1. We found the "Vin OVP response" selection can not be changed.

Is this unchangeable? Can we change to "shutdown" or "disable output"?

2. When VIN OVP happen, which flag were rising? PG, VR_Fault, SMB_ALERT#?

  • Hi Jan,

    -Not changeable.

    2. When VIN OVP happen, which flag were rising? PG, VR_Fault, SMB_ALERT#?

    In response to the VIN_OV_LIMIT being exceeded, the device will:
    • Set the OTHER bit in the STATUS_BYTE
    • Set the INPUT bit in the upper byte of the STATUS_WORD
    • Sets the VIN_OV_FAULT bit in the STATUS_INPUT register
    • Notify the host (assert the PMB_ALERT signal, if the corresponding mask bit in SMBALERT_MASK is
    not set)

    Those information can be found in the datasheet. 5.3.17.2 (56h) VIN_OV_FAULT_RESPONSE. Please kindly check it.

    Thanks
