SGM2529
5A, 5V Electronic Fuse (eFuse) with Thermal Shutdown
5A, 5V Electronic Fuse (eFuse) with Thermal Shutdown
GENERAL DESCRIPTION

The SGM2529 is a compact electronic fuse (eFuse) with a complete set of protection functions. The SGM2529 provides excellent accuracy, making it very suitable for many system protection applications.

It provides accurate over-voltage (OV) and under-voltage lockout (UVLO) protections, which ensure tight supervision of bus voltages and eliminate the need for supervisor circuits. The over-voltage (OV) protection will clamp the eFuse output at a fixed level during input voltage surges. During the input voltage transient, the internal FET remains on, which allows 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 SGM2529 is available in a Green TDFN-3×3-10L package.
