| Compliant with IEEE 802.3af/at/bt standards in PoE devices
| PG signal, provides circuit protection against overtemperature

Mouser Electronics announced on the 11th that it is supplying Maxim's PMIC 'MAX5995B'.

The MAX5995B is equipped with the interface required for Power Devices (PDs) and provides performance compliant with the IEEE 802.3af/at/bt standard for Power over Ethernet (PoE) devices.

The new PMIC provides the PD with the performance of an integrated isolated power switch featuring sensing signatures, classification signatures, and inrush current control during operation. It supports multiple event classification methods according to the IEEE 802.3bt standard and provides signals indicating Power Supply Equipment (PSE) of types 1 through 4. It also provides Power Good (PG) signals, two-stage current limiting and foldback control, and circuit protection against overtemperature.

The MAX5995B features intelligent MPS (Maintain Power Signature) function, ultra-low power sleep mode, and input low voltage cutoff with wide hysteresis. In addition, the long degliching time compensates for the drop in resistance of the twisted-pair cable and ensures glitch-free operation during the power on/off time.

Maxim's MAX5995B is manufactured in a 16-pin, 5 x 5mm TQFN power package with an operating temperature range of -40 to 85°C. It is suitable for use in applications for VoIP phones, IP security cameras, wireless access points, small cell and picocell base stations, lighting, and building automation.
