FEATURES
DESCRIPTION
Dual 12 V Protection and Blocking Control
Independent Current Limit and Fast Trip
The TPS2456 is a dual, 12 V, channel protection
(hotswap)
and
blocking
(ORing)
controller
that
Blocking Permits ORing of Multiple Inputs
provides inrush control, current limiting, overload

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

thresholds.
Temperature
The ORing control uses an external MOSFET to

Base Stations
The protection circuits may be used without blocking,
