What are the main features of the MP8017GL-Z?
The MP8017GL-Z is a highly integrated PoE (Power over Ethernet) controller designed for IEEE 802.3af powered devices. It includes an internal 100 V, 0.5 Ω MOSFET for PD input, integrated flyback MOSFETs (0.37 Ω and 0.75 Ω), and supports both active-clamp primary-side regulation (PSR) and secondary-side regulation (SSR) for flexible, efficient power conversion. With configurable switching frequency up to 650 kHz, 1.5 A switching current limit, soft-start control, and onboard EMI reduction features, it helps deliver stable, efficient power from Ethernet cables. The device also incorporates protection functions such as overload protection (OLP), over-voltage protection (OVP), and over-temperature protection (OTP) with hiccup mode.
What is it used for?
This controller is used in Power over Ethernet powered devices to extract electrical power and regulate it from PoE injector or switch lines. Typical applications include IP cameras, VoIP phones, wireless access points, networked sensors, and other PoE-powered equipment where space-efficient power supply design and compliance with IEEE 802.3af standards are important.
Does it have alternative parts?
Yes. Similar IEEE 802.3af/at PoE PD controllers are available from MPS and other vendors. Alternatives include MPS parts such as MP8010 or MP8021 series, and PoE PD controllers from companies like Texas Instruments (e.g., TPS2372/3 series), Microchip (PD7xxx series), and Analog Devices (LTC4269 series). When selecting a replacement, ensure that it meets your required power class, voltage range, protection features, and package type for compatibility with your design.
