MAX5942BCSE+

Overview

The MAX5942BCSE+ is a Power-Over-Ethernet (PoE) controller designed for Powered Devices (PDs) compliant with the IEEE 802.3af standard. It operates within a supply voltage range of 18V to 67V and draws a supply current of 400uA. The device supports a maximum power dissipation of 12.95W and functions reliably across an operating temperature range of 0°C to +70°C. Packaged in a 16-SOIC format, this component integrates essential control logic for PoE applications without internal switches.

Feature Summary

Complies with IEEE 802.3af standards for Power-over-Ethernet interfaces
Designed specifically for Powered Device (PD) applications
Operates on dual-supply voltage ranges from 18V to 67V

Applications

IEEE 802.3af compliant network infrastructure equipment
Powered VoIP telephones and wireless access points
Security cameras and surveillance systems requiring PoE input

Procurement Notes

Verify the specific suffix 'T' if tape-and-reel packaging is required, as the base part number may imply tube packaging. Confirm end-of-life status through official Analog Devices channels, as distribution availability varies by region. Ensure the design accommodates the specified 16-SOIC footprint and thermal requirements for the target application environment.

Selection Notes

Select this component when designing IEEE 802.3af Powered Devices requiring external switch management. The absence of internal switches necessitates an external MOSFET configuration. Verify that the system power budget aligns with the 12.95W maximum dissipation limit and that the operating temperature range meets the environmental constraints of the deployment location.

Part Context

This part belongs to the Maxim Integrated PoE controller family, now under Analog Devices. It serves as a dedicated interface solution for distributing DC power alongside data over Ethernet cables. The MAX5942BCSE+ complements other controllers like the MAX5941 series by providing standardized compliance features for PD implementations in modern networking hardware.
