Product details

Hot swap controller with OVP/UVLO and programmable current limit

The LTC4281CUFD#PBF: It operates from a 2.9V to 33V supply and draws 3.5 mA quiescent current. The controller integrates overvoltage protection (OVP) and undervoltage lockout (UVLO), and allows the user to program the current limit threshold. It does not contain an internal pass switch — an external N-channel MOSFET handles the power path, giving the designer control over the FET's Rds(on) and thermal performance.

The QFN package is surface-mount and ships in tube.
