LINEAR 2PB_HVhotswap High Voltage Hot Swap Controllers
This document provides technical specifications and descriptions for a series of High Voltage Hot Swap Controllers manufactured by Linear Technology. The devices are designed to manage power delivery in systems requiring protection against voltage steps and current spikes, operating up to 80V or higher depending on the specific part.
The datasheet covers several models, including the LT4250 (negative hot swap with circuit breaker), LTC4251B/LTC4252C (active current limiting), LT4261 (I2C interface monitoring), and positive voltage variants like the LT4256 and LTC4260. Key features highlighted include adjustable inrush limits, foldback current limiting, undervoltage/overvoltage protection, and various fault handling modes such as latchoff or auto-retry.

What happens when the current limit is active for more than 500 µs?
If the current limit remains active for over 500 µs, the electronic circuit breaker trips, pulling the GATE pin low and turning off the external MOSFET.
