FP0030 Minimizes Voltage Drop to Save Power & Maintain Functionality

Supertex, Inc. introduced FP0030, a 20V current limiting protection device. The FP0030 can be considered as a normally closed switch with a typical resistance of 4.5 ohms. The IC starts to turn off when the voltage drop across its two terminals exceeds a nominal value of ±1.5V. In the off state, the FP0030 can withstand up to ±20V across its terminals and allow typical current of 700uA to flow through it.

The FP0030 may also be used as a resettable fuse to protect power lines against output short circuit conditions. Its fast switching speed protect the system against abrupt over current conditions.
“Supertex’s FP0030, with its small 3-pin package and no external supplies needed, provides Ethernet system designers a space-saving and easy-to-layout solution,” states Jimes Lei, Director of Applications Engineering for Supertex. “The IC features low on-resistance of typically 4.5 ohms for minimal signal attenuation.” The FP0030 is available in a three lead SOT-23 package (FP0030K1-G). The part is RoHS compliant. Samples are available from stock. Lead-time for production quantities is 4-6 weeks ARO. Pricing is US$0.38 each for FP0030K1-G in 1K quantities.
