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 undervoltage 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.
