PoE-PD Interface Features and Benefits

7/2/196

Differentiating features Typical application schematics

Other features & specifications

Interface controller negotiates power and protection for devices powered by Ethernet cables

– Programmable classification current– Temperature monitoring, with max Tj to 150°C– Adjustable UVLO option– Integral thermal shutdown– 3.0 kV cable ESD protection to protect against hot swap events

that can occur in harsh environments and outdoor installations

– IEEE 802.3af (13.5W) and .3at (25W) compliant devices, allowing support for both power hungry devices and existing PoE applications

– Integrated DC-DC covertor in NCP108X series, providing power delivery and regulation to the application

– Non standard 40W capability with .3at devices– Operation current limit up to 1100 mA, for extended power

ranges (NCP1081/83)– Option for auxiliary supply support– Open drain power good indicator– Low on resistance hot swap switch

Evaluation board – NCP1095GEVB and NCP1096GEVB
