PD69108 Datasheet
Microsemi’s PD69108 Power over Ethernet (PoE) Manager integrates power, analog and state of the art logic into a single 48 pin, plastic QFN package. The device is used in Ethernet switches and Midspans, enabling network devices to share power and data over the same cable. The PD69108 device is an 8 ports, mixed-signal, high-voltage PoE driver. It enables detection of IEEE802.3at-2009 compliant Type 1 and Type 2 PDs (Powered Devices), ensuring safe power feeding and disconnection of ports with full digital control and a minimum of external components. The PD69108 executes all real time functions as specified in the IEEE802.3af-2003 (“AF”) and IEEE802.3at-2009 High Power (“AT”) standards, including load detection and “AF” and “AT” classification. In addition, the PD69108 features Multiple Classification Attempts (MCA) port status monitoring, and provides system level activities such as power management and MIB support for system management. The PoE device is designed to detect and disable disconnected ports utilizing DC disconnection methods, as specified in the IEEE 802.3af-2003 and IEEE802.3at-2009 standards. The unit provides PD protection such as over-load, under-load, over-voltage and short-circuiting. It supports supply voltages ranging from 44 to 57 VDC with no need for additional power supply sources. The chip includes built-in internal thermal protection. Optionally, the PD69108 can detect legacy/pre-standard PD devices. The PD69108 is a low power device using an internal MOSFET and an external 0.36 ? sense resistor.

PD-5036 Datasheet
The PD5036 is a unique pulse width modulator controller, designed primarily for a variety of high voltage sinusoidal telephone ring generator applications. The PD5036 is suitable for applications requiring up to 6 Watt and provides all necessary controls for implementing advanced overload protection, zero crossing relay switching synchronization, Off-Hook detection, multiple ringing frequency selection and output amplitude adjustment. The power train, designed to be used with the PD5036, is an isolated, open loop flyback topology. The PD5036 generates a PWM signal, which drives a FET transistor that switches the primary of a flyback transformer. This produces a rectified half sine wave on the secondary side of the transformer. An additional control signal synchronizes a 4-output transistor bridge, which converts the rectified half sine wave to full sine wave. In order to maintain the ring generator’s input to output isolation, the synchronization signals control the bridge via an opto coupler pair. The controller also includes overload protection, A/D function for measuring the input voltage, and a report signal for indicating over current. The PD5036 is a cost-effective solution for applications using more than 10,000 units. For quantities less than 10,000 units, the most economical solution is a modular sine wave ring generator (PCR-SIN01A Series, PCR-SIN03B Series, or the PCR-SIN06 Series).
