• Manufacturer Part Number: max5969a
• Description: Ieee 802.3af/at-compliant, Powered Device Interface Controllers With Integrated Power Mosfet
• Manufacturer: Maxim Integrated Products, Inc.

IEEE 802.3af/at-Compliant, Powered Device Interface
Controllers with
Note 3: All devices are 100% production tested at T
Note 4: The input offset current is illustrated in Figure 1.
Note 5: Effective differential input resistance is defined as the differential resistance between V
Note 6: Classification current is turned off whenever the device is in power mode.
Note 7: UVLO hysteresis is guaranteed by design, not production tested.
Note 8: A 20V glitch on input voltage that takes V
Note 9: In power mode, current-limit foldback is used to reduce the power dissipation in the isolation MOSFET during an overload
