TPS25942A: TPS25942A / Unused DMODE pin

Part Number: TPS25942A

Hi,

Please let me ask about DMODE pin.

  1. Which do you recommend DMODE pin should be left open or tied to GND when it's unused?
  2. Does DMODE pin have internal pull down resistor or current source?

Best Regards,

Satoshi / Japan Disty

    Hi Satoshi,

    DMODE pin is pulled to ground thorough an active 1uA current source. Range is specified in the datasheet as "DMODE input leakage current". This helps to pull DMODE pin to ground when it is floating. When not used, DMODE pin can be left open or tied to GND

    Best Regards
