The input voltage range spans 2.7 V to 23 V, covering common 3.3 V, 5 V, 12 V, and 15 V power buses. At 5.5 A continuous output, this eFuse can protect a 5 V rail delivering over 27 W or a 12 V rail delivering over 66 W. The actual current limit is set by the external resistor — the 5.5 A rating is the maximum the internal FET can handle under the stated conditions.
Temperature grade drives deployment scope
The 125°C ceiling means the eFuse can sit on a board with moderate self-heating and still hold its protection thresholds — derate the output current above 85°C per the datasheet curve.
Package and footprint — 2x2 mm VQFN
Housed in a 10-VQFN-HR (2x2) package, this is a compact, low-profile device. The supplier device package is 10-VQFN-HR (2x2), and the general package case is 10-VFQFN.
Sourcing reality — active, but not a catalog stock item
The ROHS3 compliance means no exemption issues for EU or similar markets. For volume or lead-time visibility, submit an RFQ.
