Hi,
The datasheet states that if controlling the EN is required that use open-drain output logic.
My problem is that during power up the controlling logic output is not undefined so I wish to place a pull down resistor on the TPS EN input to insure that it will not output a voltage during Vin power up. when doing that the input is no longer floating and the controlling logic needs to be defined as high to enable the TPS.
Is that OK or must I float the Enable input in order to enable the TPS?
Thanks,
Itai
