TPS61021A: TPS61021A

Part Number: TPS61021A

Using this part in a battery powered application.

Does this part provide reverse wiring protection (battery installed backwards) ?  Or would a diode (as a example) still be required on the output to prevent the circuits/IC's from potentially being damaged? 

When EN is disabled, the part enters shutdown mode.  Is Vin just pathed thru to Vout in this case?

    Hi Mike,

    Thank you for using the TPS61021A.  You need an external diode to protect against reverse batter polarity mistake.

    This IC has a true shutdown feature, namely when it is in shutdown by pulling EN low, there input is disconnected from the output. 

    Thanks,
