SLVSBI8 –JULY 2012  
Dual 12 V Protection and Blocking Controller  
Check for Samples: TPS2456A

FEATURES  
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.

Dual 12 V Protection and Blocking Control  
Independent Current Limit and Fast Trip  
Blocking Permits ORing of Multiple Inputs  
Power Good and Fault Outputs  
Analog Current Monitor Outputs  
-40°C to 125°C Operating TJ  
The ORing control uses an external MOSFET to  
block reverse current when an input is shorted.  
Systems with closely matched supply voltages and  
feed networks can supply current from both supplies  
simultaneously.  
QFN36 Package  
APPLICATIONS  
The MONx output provides an accurate analog  
indication of load current.

The protection circuits may be used without blocking,  
and the blocking may be used without protection.  
Internal connections prevent implementation of these  
as four fully-independent functions.  
Base Stations  
Configurable for  
The TPS2456 and TPS2456A have identical  
Electrical Characteristics tables. The TPS2456A has  
reduced sensitivity to input supply slew rate  
variations. It is recommended for all new applications.
