Microchip Technology PD69101
the PD69101 executes all real-time functions as specified in the IEEE 802.3af-2003 (AF) and IEEE 802.3at high-power (AT) standards, including load detection, AF and AT classification, and multiple classification attempts (MCA). The chip includes built-in internal thermal protection, and two LEDs provide port state and port type (AF/AT) indication. Integrating power, analog, and state-of-the-art logic, the PD69101 fits into a single 24-pin plastic QFN package.| Part No. | PD69101 |
