GENERAL DESCRIPTION

The SGM2521/SGM2521A/SGM2522/SGM2522A are

compact, feature rich eFuse with a full suite of

protection functions. The wide operating voltage allows

control of many popular DC buses. The precision ±10%

current limit, at room temperature, provides excellent

accuracy making the SGM2521/1A/2/2A well suited for

many system protection applications.

Load, source and device protection are provided with

multiple programmable features including over-current

(OC), over-voltage (OV) and under-voltage (UV). 3%

threshold accuracy for UV and OV, ensures tight

supervision of bus voltages, eliminating the need for

supervisor circuitry. Fault flag output (nFLT) is provided

for system status monitoring and downstream load

control.

The SGM2521/1A/2/2A are available in Green SOIC-8

and TDFN-2×3-8BL packages and operate over a

temperature range of -40℃ to +85℃.
