Nick Flaherty reports on the first integrated power device jack combining PoE plus power device controller and bridge rectifiers with gigabit magnetics in a drop-in single port connector solution.
Molex has launched its next-generation Power over Ethernet (PoE) connector that integrates the magnetic PDJack controller into an RJ45 format. The single-port controller integrates power device controller circuitry and PoE functionality in a single solution for up to 75 per cent space savings on a PCB compared to discrete solutions.
“Based on the RJ45 connector, the fully compliant PDJack connector eliminates complex design and testing for lower direct costs and faster time-to-market,”said Diarmuid Cullinan, integrated products division manager at Molex. “The PDJack connector with integrated power device controller circuitry plus Ethernet connectivity simplifies installation and the PoE plus infrastructure of networking devices.”[Page Break]
This is the industry’s first integrated power device jack combining PoE plus power device controller and bridge rectifiers with gigabit magnetics in a drop-in single port connector solution and the PDJack connector supports functions of all PoE PSE type as required for IEEE802.3at compliance, interoperability, thermal management and EMI standards.
In developing the PDJack connector, Molex partnered with Microsemi and used their PD controller PD70200, which meets all power device standards including detection, classification, integrated isolation switch with inrush current limiter and over-current protection, and two events classifications for PoE plus power.
A fully-shielded connector with integrated electro-static discharge protection, the robust PDJack connector design is suitable for a wide operating range and passive airflow environments. [Page Break]
Available in Class 0, 1, 2, 3 and 4 for optimal power design, the PDJack connector supply up to 25.5W power at 37V to 57V. Two pins output power and standard signal pins provide Ethernet connectivity, with additional pins allowing power-up of external DC to DC converter.
The PDJack manages all the communications with the switch/router PoE controllers to negotiate power requirements and manage safe power-up and power down of IP devices, wireless access points, control panels, vision systems and POS units.
