CONCLUSION

Vishay Siliconix current-sensing power MOSFETs enable

implementation of a simple solution for incorporating

supervisory protection features such as overcurrent and/or

short circuit. This approach offers the freedom and flexibility of

control-circuit design, though the accuracy of measurement is

not suitable for current-control applications. Virtually any

power MOSFET from the Vishay Siliconix product range can

be supplied with a current-sensing feature.
