The LTC4252BIMS-2#TRPBF from LT is a negative voltage Hot Swap controller that enables safe insertion and removal of boards from live backplanes. This controller manages output current through three stages: a timed circuit breaker, active current limiting, and a fast feedforward path to limit peak current during faults.
Key electrical features include a typical current limit of 2.5A and tight ±1% accuracy for undervoltage and overvoltage thresholds, as specified for the LTC4252C variants. The device supports adjustable undervoltage and overvoltage detection, ensuring the load operates within the desired supply range. It also incorporates an adjustable soft-start circuit to control inrush current during startup.
The LTC4252BIMS-2#TRPBF is available in an 8-pin or 10-pin MSOP package. Its design allows for safe operation with very high supply voltages due to shunt regulation. The controller includes a multifunction timer for delayed startup and circuit breaker response time, which can be accelerated by sensing excessive MOSFET drain voltage to keep the MOSFET within its safe operating area (SOA). The LTC4252-2 variants, including this part, offer automatic retry after a fault condition.
The typical current limit for the LTC4252BIMS-2#TRPBF is 2.5A.
The undervoltage/overvoltage threshold accuracy is ±1%.
The LTC4252BIMS-2#TRPBF is available in 8-pin and 10-pin MSOP packages.
The RoHS status is RoHS3 Compliant.
The Moisture Sensitivity Level (MSL) is 1 Unlimited.
