PD69208MILQ-TR-LE Information

Description

The PD69208MILQ-TR-LE is a Power Over Ethernet (PoE) controller designed for military and aerospace applications. It's a wide input voltage DC-DC converter that can operate in rugged environments, making it suitable for use in communication systems, radar systems, avionics, and missile guidance systems. This device supports 8 independent PoE channels, complying with IEEE 802.3af, IEEE 802.3at, and IEEE 802.3bt standards. It features a single DC voltage input with built-in regulators, wide ambient temperature range, and on-chip over-temperature thermal protection. The PD69208MILQ-TR-LE also offers programmable threshold temperature alarm limits, interrupt out pins for system and port events, and forced port power ON function. In summary, the PD69208MILQ-TR-LE is a reliable PoE controller designed to provide power conversion in harsh environments, making it an ideal solution for military and aerospace applications.
