Texas Instruments TPS23525 -48V Hot Swap & ORing Controllers

Texas Instruments TPS23525 -48V High-Performance Hot Swap and ORing Controllers enable high-power telecom systems to comply with stringent transient requirements. The TPS23525 has a 200V absolute maximum rating allowing an easier lightning surge test (IEC61000-4-5) survival. The soft start cap disconnect allows for the use of smaller hot swap FETs. This limits the inrush current without damaging the transient response. The Gate Sourcing Current set at 400µA allows a fast recovery, which helps to avoid system resets during lightning surge tests. The TPS23525 offers protection features such as accurate undervoltage and overvoltage protection with programmable thresholds and Hysteresis.
