General Description

The TPS2456A is a dual, 12 V, channel protection (hotswap) and blocking (ORing) controller that provides inrush control, current limiting, overload protection, and reverse current blocking.

The current sense topology provides both accurate current limits and independent setting of current limit and fast trip thresholds.

The ORing control uses an external MOSFET to block reverse current when an input is shorted.
