Product Overview
The MP8009AGV-Z is the Z-reel ordering option of MPS’s MP8009A integrated PoE powered-device power converter. The device combines the IEEE 802.3af/at PD front end with a flyback/forward power controller, reducing the number of separate high-voltage interface and control devices needed in an isolated PoE supply.
The PD interface includes detection, one-event and two-event classification, a 120 mA inrush-current limit, an 840 mA operating-current limit and a 100 V integrated pass MOSFET. On the converter side, the controller supports primary-side-regulated or secondary-side-regulated flyback operation as well as secondary-side-regulated active-clamp forward designs.

Design Considerations
The 840 mA PD current limit is an interface protection threshold, not a direct statement of available regulated output current. Transformer ratio, topology, PoE class, conversion efficiency and thermal limits still determine the usable output power.
MPS lists MP8009AGV-Z and MP8009AGV-P as the same device with different reel-size suffixes. Procurement should preserve the requested Z suffix when reel configuration matters, while the electrical design should follow the MP8009A device specification.
Quality & Verification Support
Third-party inspection or testing can be arranged according to customer requirements. Testing fees are borne by the buyer. Additional verification requirements can be discussed before shipment. After an order is placed, physical product, label, packaging, and Date Code photos may be provided where appropriate.
