TLV62130A: TLV62130A Discharge Function

Part Number: TLV62130A

Hi, 

TLV62130A has discharge function in PG pin.

My customer want to calculate the R3 resistance value for power down sequence,

but datasheet doesn't written the on resistance of the internal FET.

Do you have the value of on resistance(typ & max) ?

Regards,

Taichi Nakamura

    The datasheet specifies a maximum sink current into PG of 10mA (page 5).
    The continuous current can be 2mA (e.g. page 10) and the test condition for logic low is 2mA yielding in 300mV max and 70mV typ voltage at PG (page 6). If I take this data I can calculate 35mOhm typ and 150mOhm max resistance from PG to AGND.
