Microchip PD70224LILQ-TR

Overview

The entire drive circuitry for driving the MOSFETs is on-chip, including a charge pump for driving the high-side N-channel MOSFETs. The total forward drop (bridge offset) introduced by the IdealBridge™ rectifier is only 180mV at 0.6A, compared to a standard bridge rectifier that typically presents 2000mV of forward drop. PD70224  IdealBridge™ can support over 1A current, making it the ideal choice not only for modern energy-saving 2-pair applications compliant with IEEE802.3af and IEEE802.3at (Type 1 and Type 2), but also 4-pair Powered Devices such as for UPOE (51W) and POH (Power over HDBase-T, 73W). In addition, PD70224ILQ-TR is capable of helping to identify at the physical layer itself whether a 2-pair PSE or a 4-pair PSE is providing power over the cable. It does that by sensing the voltage on the line (un-rectified) side of the pairs.
