GENERAL DEscriptION

The SGM2533 and SGM2534 are compact, feature rich eFuses with a full suite of protection functions. The precision ±15% current limit provides excellent accuracy and makes the devices well suited for many system protection applications.

There are two over-voltage protection options: 5V system for SGM2533 and 12V system for SGM2534. The over-voltage protection (OVP) will clamp the eFuse output at a fixed level during input voltage surges. During the input voltage transient, the internal MOSFET remains on, allowing the load to continue to operate. If the transient duration remains long, the accumulated heat will cause the eFuse thermal shutdown. once in thermal shutdown, latch-off and auto-retry thermal options are available.

The SGM2533 and SGM2534 are available in a Green TDFN-3×3-10L package.
