Overview
The TPS23523PWR, produced by Texas Instruments, is an integrated hot swap and single OR-ing controller designed to enable high power telecom systems to comply with stringent transient requirements. This device features a 200-V absolute maximum rating, making it robust enough to survive lightning surge tests (IEC61000-4-5). The TPS23523PWR includes a soft start cap disconnect, which allows the use of smaller hot swap FETs by limiting the inrush current without compromising the transient response. It also integrates a dual hot swap gate driver, which saves space and reduces the bill of materials (BOM) cost in high power applications requiring multiple hot swap FETs. The device offers fast recovery with a 400-µA sourcing current, helping to avoid system resets during lightning surge tests.
