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 ±7% current limit, at room temperature, provides excellent accuracy and makes 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 and eliminates 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℃.
