Part Number: LM5066I

Hi TI,

Can LM5066I read reverse current (negative current) through its I2C send data to MCU?

Can the OVP reaction be latch off instead of retry?

Thanks

LM5066I cannot read reverse current (negative current) through its I2C send data to MCU.

No, the OVP reaction cannot be latch off.

I believe, although it cannot read reverse current through its I2C, it can still support reverse current because the SENSE to VIN_K absolute max rating is -0.3V to 0.3V, am I right?

Does LM5069-1 and LM5069-2 have the same features i.e. can support reverse current and OVP reaction is only retry?

Reverse current will flow through the body diode of the MOSFET. There won't be any protection against the flow of reverse current.

LM5069-1 and LM5069-2 are same as LM5066.
