Does the eFuse IC (electronic fuse) have reverse current blocking(RCB) function?

Toshiba eFuse IC TCKE8 Series can provide reverse current blocking (RCB) function with an external MOSFET.
For example, if there is a possibility of the reverse current from COUT to eFuse IC, Connect an external N-channel MOSFET to prevent reverse current as shown in the figure below.
TCKE712BNL is a product with a built-in RCB function, and does not require an external N-channel MOSFET.
