The SGM2521/SGM2521A/SGM2522/SGM2522A are compact electronic fuses (eFuses), which can operate from 4.5V to 24V single supply. SGM2521/1A/2/2A are designed for a wide range of applications and can provide ±7% current limit accuracy at TA = +25℃.
Internal protection functions are provided for over-current protection (OCP), over-voltage protection (OVP) and under-voltage lockout (UVLO). Fault conditions are indicated by the nFLT pin.
The threshold accuracy of UV and OV is 3%, which ensures close monitoring of bus voltage and reduces the demand of monitoring circuit.
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℃.
