Microsemi / Microchip PD69104B1ILQ Power Switch IC

Microsemi / Microchip PD69104B1ILQ Power Switch IC enables network devices to share power and data over a single cable. The PD69104B1 supports supply voltages between 44V and 57V without additional power supply sources. This power switch IC includes built-in thermal protection. The device integrates power, analog circuitry, and state-of-the-art control logic into a single 48-pin plastic QFN package. Both Ethernet switches and Midspans employ this power switch IC chip. The PD69104B1 device is a 4-port, mixed-signal, high-voltage Power over Ethernet (PoE) Manager. This power switch IC supports three modes of operation: MSCC extended auto mode, semi-auto mode, and auto mode. Microsemi / Microchip PD69104B1ILQ power switch IC provides power device real-time protection through overload, under-load, over-voltage, over-temperature, and short-circuit mechanisms.
