Hi TI Experts.

Please let me confirm the following question.

[Question]
Would you teach me the electrical specification of the absolute maximum current rate of TRX_SW pin?

My customer would like to know how much current on TRX_SW pin of CC1200/CC1125 can it pull.

If you have any questions, please let me know.
Best regards.

    We don't have that number since the intent with the TRX_SW pin is to provide a low resistance to ground when in Tx.

    How are they planning to use this pin since they need to know the current?

    Hi TER,

    Thank you for your response.

    They use this pin as TRX switch function. Not use for other function.
    They just would like to know the tolerance of this pin in terms of current rating.

    If you have any question, please let me know.
    Best regards.

    If they use the switch as shown in the reference designs they don't need to know how much current the node could drain. For this usage very limited amount of current will flow through this pin.
