Description

General part information

LT4293 Series

The LT4293 is an LTPoE++/IEEE 802.3af/at/bt-compliant powered device (PD) interface controller. The T2P output distinguishes between LTPoE++ and IEEE 802.3bt power sourcing equipment (PSE) during mutual identification and negotiation of available power.The LT4293 utilizes an external, low RDS(ON), N-channel, hot swap MOSFET and supports the LT4320/LT4321 ideal bridges, to extend the end-to-end power delivery efficiency and eliminate costly heat sinks. The LT4293 also includes a power good output, onboard signature resistor, undervoltage lockout, and thermal protection. Start-up inrush current is adjustable with an external capacitor. Auxiliary power override is supported as low as 9V with the AUX pin.The LT4293 can be configured to support all possible LTPoE++, 802.3bt, 802.3at and 802.3af power levels with external component changes. Pin-for-pin compatibility with the LT4275 and LT4294 family of PD Interface Controllers enables easy migration between LTPoE++ PDs and IEEE 802.3bt-compliant PDs.ApplicationsHigh Power Wireless Data SystemsOutdoor Security Camera EquipmentCommercial and Public Information DisplaysHigh Temperature Industrial Applications
