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.
