The TPS23525 is an integrated hot swap and dual OR-ing controller that enables high power telecom systems to comply with stringent transient requirements. The 200-V absolute maximum rating makes it easier to survive lightning surge tests (IEC61000-4-5). The soft start cap disconnect allows for the use of smaller hot swap FETs by limiting the inrush current, without hurting the transient response. The 400-µA sourcing current allows fast recovery, which helps to avoid system resets during lightning surge tests. The dual current limit makes it easier to pass brown outs and input steps such as required by the ATIS 0600315.2013. Finally, it offers accurate undervoltage and overvoltage protection with programmable thresholds and hysteresis.
The TPS23525 integrates a dual OR-ing controller, making it ideal for –48-V systems fed by two redundant supplies.
