Texas Instruments TPS23521PWT
The TPS23521 is a high performance hot swap that 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.
