TPS25981: RFLTB Internal pulldown resistance

HYUNSEOK LIM

Part Number: TPS25981

Tool/software:

I am considering applying TPS259814ARPW, and the datasheet states that RFLTB has an internal pull down resistance of 12.57ohm. I would like to get confirmation from TI if this is actually correct.

Thanks.

Hi Hyunseok,

FLTb is open drain pin and 12.57Ohms is the typical resistance of pull down path inside the device. You will have to use an external pull up resistance to ensure the current remains in mA.
