LT4293 Interface Controller

Analog Devices LT4293 Interface Controller is an LTPoE++/IEEE 802.3af/at/bt-compliant powered device. 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. It supports the LT4320/LT4321 ideal bridges, extending the efficiency of the end-to-end power delivery and eliminating costly heat sinks. The LT4293 has good power output, an onboard signature resistor, undervoltage lockout, and thermal protection. The startup inrush current is adjustable with an external capacitor. Auxiliary power override is supported as low as 9V with the AUX pin.
