Description
PD64001 features
The PD64001 meets all IEEE-802.3af-2003 standard requirements such as:
• Multi – point resistor detection
• PD classification function
• AC disconnect and DC disconnect function
• Supports Back-off feature for Midspan implementation
Including support for high power and 2-events classification.
The PD64001 requires a single DC voltage source: 46V to 57V. No additional voltage sources
(e.g. 3.3V/5V) are required for the PoE system’s operation.
The PD64001 can operate over a wide temperature range: -40°c to +85°c.
This wide temperature range allows the integration of the PD64001, into small unventilated
boxes and operates in harsh environments.
The PD64001 has a very low thermal dissipation. The Rsense in PD64001 applications is only
1Ω to keep the peripheral components in low temperatures as well.
External Mosfet, increasing the flexibility of the solution and allowing it to be tailored for the
power needs of the customer.
The PD64001 utilizes a dedicated pin, allowing an immediate disconnection of the PoE port.
This disable-port pin can be controlled via the Host CPU.
Pre-Standard PD
Detection
Detection of Cisco
Devices
LED Support
Enables detection and powering of pre-standard power devices (PDs).
Enables detection and powering of all Cisco devices including pre-standard terminals.
Direct driving of the LED circuitry. It allows the designer to implement a simple LED circuit,
indicating whether an IEEE802.3af or IEEE802.3at device is connected.
