Part Number: TPS22917

hi

when the tps22917 is disable, the RCB is not working, right?

what woule happen if VOUT = 4V and VIN =1-2V?

will there be reverse current flowing?

is there any risk to damage the part?

thanks a lot in advance

KR

    Hi Vincenzo, 

    Thanks for reaching out on E2E!

    The TPS22917 has reverse current blocking functionality when the device is either enabled or disabled, hence the "always-on RCB". Even if VIN = 1V and VOUT = 4V, the I_IN,RCB (reverse leakage) will end up being less than 1uA. 

    Thanks,
