The MAX15091AETI+T is an integrated hot-swap controller solution from Analog Devices Inc./Maxim Integrated, designed for applications requiring the safe insertion and removal of circuit line cards from a live backplane. This device integrates an 18mΩ (typ) power MOSFET and an electronic circuit breaker, supporting supply voltages from 2.7V to 18V.
Key features include programmable inrush current control, adjustable circuit-breaker current limit, and programmable slew-rate control using an external capacitor. It offers overvoltage and undervoltage protection, internal overtemperature protection, a power-good output, and a fault-indicator output. The MAX15091A variant, like this part, enters autoretry mode after a fault condition.
This hot-swap controller is available in a 28-pin, 5mm x 5mm TQFN power package, suitable for space-constrained designs. It operates over an extended temperature range of -40°C to +85°C, making it robust for various industrial applications.
The device provides accurate current sensing with 170µA/A proportional output current and ±10% accuracy for overcurrent protection. It also features IN-to-OUT short-circuit detection before startup and implements foldback current limiting during startup to maintain safe operating area conditions.
