Texas Instruments  TPS23523PWT

The TPS23523 is an integrated hot swap andOR-ing controllerthat enables high power telecom systems to comply with stringent transient requirements. The 200-Vabsolute maximum rating makes it easier to survive lightning surge tests (IEC61000-4-5). The softstart cap disconnect allows for the use of smaller hot swap FETs by limiting the inrush current,without hurting the transient response. The dual hot swap gatedriver saves space and BOM cost in high power applications that require multiple hot swapFETs.The 400-µA sourcing current allows fast recovery, which helps to avoid system resetsduring lightning surge tests. The dual current limit makes it easier to pass brown outs and inputsteps such as required by the ATIS 0600315.2013. Finally, it offers accurate undervoltage andovervoltage protection with programmable thresholds and hysteresis.

The TPS23523 integrates an OR-ing controller, making it ideal for–48-V systems that require reverse hook-up protection and reverse-current protection. The OR-ingcontroller protects the output when the input drops avoiding system resets.
