TPS2592ZL, TPS2592AL - Fault Response

Other Parts Discussed in Thread: TPS2592AL

Hi,

Would you mind if we ask TPS2592ZL and TPS2592AL?

<Question>
Fault response of TPS2592ZL and TPS2592AL are latch-off.
When the UV failure occurred, which will the fault response be Auto-Retry or Latch-off?

Kind regards,

Matsumoto-san,

When the input voltage reaches the falling UVLO voltage, the device is completely off. There is no internal mechanism that tries to turn the device back on.

The device will turn back on when VIN is above the rising UVLO voltage, EN is above its turn on voltage, and there are no faults.

Regards,

Darwin

Yes, the Fault response of TPS2592ZL and TPS2592AL are Latch-off.

The Under volatge failure will turn off the the devcice and Gate signal to the internal MOSFET will be removed.

The Auto- Rety or Latch is applicable to over curent or short circuit conditions.
