High side driver demonstration board based on the VN751PT
  • active Active

The purpose of this design is to demonstrate the features of the VN751PT high-side driver.

The application offers robustness and complies with EMC industrial standards.

It implements short-circuit/overload protection and thermal management as well, achieving best in class MTBF values.

The reference design is suitable for use in programmable logic controllers (PLCs) as well as to drive generic loads which require up to 2.5 A of nominal current (the typical current limitation is 4.5 - 5 A).

Thanks to the very low RDSon (only 60 mO Typ. @ 25 °C) the device allows very low power consumption during the operation and for this reason it represent an ideal solution for IP65 / IP67 requirements. The device is compliant with IEC 61131-2 (programmable controllers international standard).
