75-V Current-Sensing MOSFET Highlights TrenchFet Family

The SUM series temperature- and current-sensing TrenchFETs, including what the company claims is the first 75-V current-sensing MOSFET, are available in a thermally enhanced D²PAK package. The 30- to 75-V TrenchFETs are designed for any application requiring temperature or current sensing, including motor drives and valve drives. They also target industrial and automotive applications, including door modules, EPS, and 12- or 42-V Powernet systems in cars. The temperature-sensing function of the SUM series devices allows the MOSFET to shut down circuitry before extreme temperature causes circuit malfunction or damage. Also, the current-sensing diode lets the MOSFET shut down circuitry when it detects excessive current, as in the case of a stalled motor or short circuit. With the D²PAK, the devices offer very low thermal resistance for this package type. With no increase in footprint, the new TrenchFETs provide thermal resistance up to 33% lower than standard D²PAKs. The devices also boast up to 20% higher current-handling capability and up to 50% higher power dissipation compared to standard D²PAKs. Maximum on resistance is as low as 4.5 m‡. The SUM TrenchFETs range in price from $0.72 to $2.14 in 100,000-piece quantities. Lead time is 10 to 12 weeks for larger orders.
