Product label
Product status link PM8805
Features
• Dual active bridge, hot swap MOSFET and PoE-PD interface in a system-inpackage
• 100 V N-ch MOSFETs with 0.2 Ω total path resistance for each active bridge • 100 V, 0.1 Ω high-side N-ch hot swap MOSFET • PoE-PD single-signature interface compliant with IEEE 802.3bt / at / af • Supports 4-pair PoE applications • Supports 12 V auxiliary sources • Identifies which kind of PSE (standard or legacy) is connected with and
provides successful IEEE802.3bt / at / af classification indication as a combination of the T0, T1 and T2 signals (open drain) • Smart operational modes • Programmable classification current with 3.
