Please let me know about two point below on Power supply off (IN1/IN2/AUX = 0V) state.
①Is TPS25810 have reverse current protection of Vout→IN1/IN2?
②When power supply off, What is CC-pin state?
（Open, Pull-down, or the other state ）
Best regards,
Satoshi
Sorry for the delay in response.
①Is TPS25810 have reverse current protection of Vout→IN1/IN2?
Yes. As can be seen from the TPS25810 datasheet specs the reverse leakage current when VIN = VEN = 0V is 3uA @6.5V.
②When power supply off, What is CC-pin state?
There are two CC pins on this device that are bi-directional. In this case, when VIN = VEN = 0V the pins are High-Z.
