LTC4291/LTC4292 4-Port PoE PSE Controllers

Analog Devices Inc. LTC4291/LTC®4292 chipsets include isolated 4-port power sourcing equipment (PSE) controllers designed for use in IEEE 802.3bt (PoE++) Power over Ethernet (PoE) systems. The LTC4291/LTC4292 Controllers offer four independent PSE ports comprised of two channels each, ensuring fully compliant support for the next generation of IEEE 802.3bt powered devices (PDs). The LTC4291 series includes a digital interface to the PSE host, while the Analog Devices LTC4292 series implements the high-voltage Ethernet power interface. The two ICs communicate using an Ethernet transformer. The transformer-isolated communication protocol replaces up to six optocouplers and a complex isolated 3.3V supply used in traditional designs.

LTC4376 Power Switch ICs

Analog Devices Inc. LTC4376 Power Switch ICs are 7A ideal diodes that use an internal 15mΩ N-channel MOSFETs. This is to replace a Schottky diode when used in diode-OR and high current diode applications. The LTC4376 switch ICs controls the forward voltage drop across the internal MOSFET to ensure smooth current delivery without oscillation. These power switch ICs reduce power consumption, heat dissipation, and PC board area. The LTC4376 power switch ICs operate from 4V to 40V operating voltage range and offers -40V reverse input protection. These switch ICs are available in 16-pin 5mm x 4mm DFN package. Applications include automotive battery protection, redundant power supplies, portable battery devices, and computer systems/servers.
