Mouser stocks PMIC for PoE from Maxim Integrated
Distributor, Mouser Electronics has announced it is not stocking the MAX5995B power management IC (PMIC) from Maxim Integrated. The small PMIC provides a complete interface for powered device (PD) to comply with the IEEE 802.3af/at/bt standard in a power over Ethernet (PoE) system.
The MAX5995B provides the PD with a detection signature, classification signature, and an integrated isolation power switch with start-up inrush current control. The IC supports a multi-event classification method as specified in the IEEE 802.3bt standard, and provides a signal to indicate from Type 1 to Type 4 Power Sourcing Equipment (PSE). The PMIC also provides a power-good (PG) signal, two-step current limit and foldback control, and over-temperature protection.
There is also an intelligent maintain power signature (MPS) function, a low-power sleep mode, an input under-voltage lockout with wide hysteresis, and long de-glitch time to compensate for twisted pair cable resistive drop and to assure glitch-free transition during power-on/-off conditions.
The MAX5995B PMIC is available in a 16-pin, 5.0 x 5.0mm TQFN power package with an operating temperature range of -40 to +85 degrees C. Suitable applications are VOIP phones, IP security cameras, wireless access points, small cell and picocell basestations, lighting, and building automation.
Maxim Integrated produces analogue devices for a variety of applications from mobile to industrial.
