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.
