PD70100A & PD70200 IEEE 802.3af/at PD Front End IC (R) TM P RODUCT D ATA S HEET KEY FEATURES DESCRIPTION The PD70100AA and PD70200 devices are part of Microsemi'sTM series of Power over Ethernet (PoE) Powered Devices chips (PD). The PD70100AA and PD70200 devices transmit integrated power and analog data in a single 12-pin package. They are used in Powered Devices (PD), thus enabling next generation network devices to share power and data over the same cable. Microsemi's new PD family offers a solution to any PD application compliant with IEEE802.3af and IEEE802.3at standards and 4-pairs extra power applications. The IC family's components can be used in both indoor and outdoor applications. The device family meets all PDside-standards such as: Detection Classification Integrated isolation switch with inrush current limiter, and overcurrent protection. Two-events classification recognition and AT flag generation (PD70200 only). In addition, the devices have a discharge mechanism for a DC/DC input capacitor, ensuring quick redetection capability in case the RJ45 plug is disconnected and reconnected within a short time span. PD70200 IC design specifically supports IEEE802.3at standard, including two-events classification detection that enables the PD to distinguish whether the connected power source equipment (PSE) is IEEE802.3at or IEEE802.3af based. The PD70100AA/PD70200 ICs are designed to support 4-pair applications for PDs that require higher power.

The PD70200 IC provides IEEE 802.3at Type 2 compliant detection of the "Two Events Classification Signature", and generation of the AT flag. This feature is available on the PD70200 IC only. Simply put, the "Two Events Classification Signature" is a means by which an IEEE 802.3at Type 2 Power Source can inform a compliant Power Device (PD) that it is AT Type 2 compliant, and as such is capable of providing AT Type 2 power levels. The Power Source communicates with a Type 2 compliant signature by toggling the VPP to VPNIN voltage twice (2 "events") during the Physical Layer Classification phase. The VPP to VPNIN voltage is toggled from the Physical Layer Classification's voltage level (13.5V to 20.9V) down to a voltage "Mark" level. Voltage "Mark" level is specified as a VPP to VPNIN voltage of 4.9V to 10.1V. PD70200 IC recognizes a VPP to VPNIN falling edge from Classification level to Mark level as being one event of the Two-Events Signature. If two such falling edges are detected, PD70200 will assert AT flag by means of an open drain MOSFET connected between AT_FLAG pin and VPNOUT. AT_FLAG pin is active low; a low impedance state between AT_FLAG and VPNOUT indicates a valid TwoEvents Classification Signature was received, and the Power Source is AT Type 2 compliant. AT_FLAG MOSFET is capable of 5mA of current and can be pulled up to VPP. DETECTION IEEE 802.3af/at compliant detection is provided by means of a 24.9K resistor connected between V PP and RDET pin. RDET pin is connected to VPNIN via an open drain MOSFET with a maximum specified RDS ON of 50. Internal logic monitors VPP to VPNIN and connects the RDET pin to VPNIN when the rising VPP to VPNIN voltage is between 2.5V and 10.1V. When rising VPP to VPNIN voltage exceeds 10.1V, the MOSFET is switched off. Once above 10.1V, falling VPP to VPNIN voltage between 2.45V and 4.85V will reconnect RDET pin to VPNIN. PHYSICAL LAYER CLASSIFICATION SOFT START AND INRUSH CURRENT PROTECTION PD70100A/PD70200 IC contains an internal isolation switch, that provides ground isolation between Power Source and PD application during Detection and Classification phases. The isolation switch is a N-channel MOSFET, wired in a common source configuration where the MOSFET's Source is connected to Power Source ground at VPNIN, and the MOSFET's Drain is connected to application's primary ground at VPNOUT. Copyright (c) 2011 Microsemi Rev. 1.1 Analog Mixed Signal Group 1 Enterprise, Aliso Viejo, CA 92656, USA; Within the USA: (800) 713-4113, Outside the USA: (949) 221-7100 Fax: (949) 756-0308 9 PD70100A & PD70200 Physical Layer (hardware) Classification per IEEE 802.3af/at is generated via a regulated reference voltage of 1.2V, switched onto the RCLASS pin. Internal logic monitors the VPP to VPNIN voltage and connects the 1.2V reference to RCLASS pin at a rising VPP to VPNIN voltage threshold between 11.1V and 13.5V. Once V PP to VPNIN has exceeded the rising threshold, there is a 1V minimum hysteresis between the VPP rising (turn-on) threshold and the VPP falling (turn-off) threshold. The 1.2V reference stays connected to the R CLASS pin until the VPP to VPNIN rising voltage exceeds the upper turn-off threshold of 20.9V to 23.9V. The 1.2V reference voltage is disconnected from the RCLASS pin at VPP to VPNIN voltages above the upper threshold. Classification current signature is provided via a resistor connected between RCLASS pin and VPNIN. The classification current is therefore the current drawn by the PD70100A/PD70200 IC during the classification phase, and is simply the 1.2V reference voltage divided by the RCLASS resistor value. The maximum current available at the RCLASS pin is current limited to 55mA (typical). PD70100A & PD70200 (R) TM IEEE 802.3af/at PD Front End IC P RODUCT D ATA S HEET THEORY OF OPERATION Internal logic monitors VPP to VPNIN voltage and keeps the MOSFET in a high impedance state until VPP to VPNIN voltage reaches turn-on threshold of 36V to 42V. Once VPP to VPNIN voltage exceeds this threshold, the MOSFET is switched into one of two modes. The mode into which the MOSFET is switched is determined by the voltage developed across the MOSFET, or put another way, the VPN OUT to VPNIN differential voltage. Two modes are defined below: Isolation Switch Modes VPNOUT to VPNIN Mode Description > 0.7V Soft Start Mode Limits VPNOUT current to 240mA (typical) 0.7V Normal Operating Mode Limits VPNOUT current to 1.8A (typical) By controlling the MOSFET current based on VPNOUT to VPNIN voltage, inrush currents generated by fully discharged bulk capacitors can be limited. This method limits current to a maximum of 350mA, compliant with IEEE 802.3af/at specification. Soft Start current limiting is required to reduce occurrences of voltage sag at the PD input during device power-up. A comparison is shown in Figure 3. VPD [V] 60 50 40 Soft startup Slope 30 Hard startup 10 T [ms] OVER-CURRENT PROTECTION Over-current protection is provided on the PD70100A/PD70200 IC using the Isolation MOSFET Switch, which limits the VPNOUT current to 1.8A during normal operation. See previous description of Soft Start. POWER GOOD During Soft-Start mode, the PD70100A/PD70200 IC monitors VPNOUT to VPNIN differential voltage. When this voltage is less than 0.7V (max.), the IC enters normal operation mode and the isolation switch current limit is increased to 1.8A (typical). At this same 0.7V (max.) threshold the Power Good signal is asserted by means of an open drain MOSFET between PGOOD and VPNOUT. PGOOD pin is active low; a low impedance state between PGOOD and VPNOUT indicates the Soft-start mode has finished and the isolation switch has transitioned into normal operating mode. PGOOD MOSFET can handle current of 5mA and can be pulled up to VPP. Voltage sag! Figure 3. Comparison of input voltages without Soft Start (Hard startup), and with Soft Start (Soft startup).

PD70100A and PD70200 ICs are different in their respective isolation MOSFET's continuous current handling capability: PD70100A: 450mA (max.) PD70200: 1123mA (max.) An adequate heat sink for the PD70100A/PD70200 IC's exposed pad must be provided to achieve these current levels without damaging the IC. A large, heavy copper fill area and/or a heavy ground plane with Thermal Vias is recommended. Electrically the exposed pad ground plane should be connected to VPNIN. Internal logic monitoring VPP to VPNIN will place the isolation switch MOSFET in a high impedance state if voltage between VPP and VPNIN drops below 31V to 34V. PD70100A & PD70200 TM (R) IEEE 802.3af/at PD Front End IC P RODUCT D ATA S HEET THEORY OF OPERATION AUXILIARY VOLTAGE OUTPUT PD70100A/PD70200 IC provides a 10.5V (typical) regulated output to be used as a start-up supply for DC/DC controllers whose VCC is provided via a bootstrap winding. This regulated supply is available at VAUX pin, and is referenced to VPNOUT pin. VAUX supply is designed for low-duty operation, and should not be designed as a primary housekeeping supply. The current capability is continuous 2mA, with 10mA peak (10ms). VAUX output is current-limited at 10mA (min.). For stability, the VAUX regulator requires a minimum of 4.7F ceramic capacitor connected directly between VAUX and VPNOUT pins. THERMAL PROTECTION Both PD70100A and PD70200 IC include temperature sensors which individually monitor both the isolation MOSFET and the Classification Current Source for over temperature conditions. In case of an over temperature condition, the sensor will activate protection circuitry which will disconnect its respective monitored function. BULK CAPACITOR DISCHARGE The bulk capacitor discharge circuitry eliminates the need to place a diode in series with the VPP line to prevent an application's bulk capacitance from discharging through the detection resistor and the isolation switch MOSFET's body diode. Discharge current through the detection resistor can cause failure of the detection signature in cases where a PD is connected and the bulk capacitance is not fully discharged. During normal operation, PD70100A/PD70200 IC continuously monitors voltage at VPP to VPNIN. Should VPP to VPNIN voltage fall below isolation switch turn-off threshold (31V to 34V), isolation switch MOSFET is immediately placed in a high-impedance state. At this point the internal logic monitors the voltage at VPP to VPNOUT. If VPP to VPNOUT voltage is between 1.5V to 32V, a 23mA (min.) constant current source is connected across the VPP and VPNOUT pins. This constant current source provides bulk capacitor discharge. A 220F bulk capacitance can be discharged from 32V to 1.5V in a maximal period of 292ms.
