The LT4256-2IS8#TRPBF from Analog Devices is a high-voltage Hot Swap controller that enables safe insertion and removal of boards from live backplanes. It controls supply voltages ranging from 10.8V to 80V, driving an external N-channel MOSFET switch.
Key features include an adjustable analog foldback current limit and overcurrent fault detection. The LT4256-2 variant offers automatic restart after a timeout delay, while the LT4256-1 latches off until the UV pin is cycled low. The PWRGD output indicates when the output voltage rises above a programmed level, and undervoltage protection is programmable via an external resistor string.
This controller is suitable for applications such as electronic circuit breakers, industrial high-side switches, and distributed power systems, particularly for 12V, 24V, and 48V systems. It is available in an 8-pin SO package, pin-compatible with the LT1641.
The device operates within a temperature range of -40°C to 85°C and is surface-mounted. It features programmable current limit, fault timeout, slew rate, and undervoltage lockout (UVLO).
