Introduction

AI Translation

The LT4294 is an IEEE 802.3af/at/bt-compliant powered device (PD) interface controller. The T2P output indicates the number of classification events received during IEEE 802.3bt-compliant mutual identification and negotiation of available power. The LT4294 utilizes an external, low RDS(ON) N-channel hot swap MOSFET and supports the LT4320/LT4321 ideal diode bridges, to extend the end-to-end power delivery efficiency and eliminate costly heat sinks. The LT4294 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 LT4294 can be configured to support all possible 802.3bt, 802.3at and 802.3af power levels with external component changes. Pin-for-pin compatibility with the LT4275 family of PD Interface Controllers enables easy migration between LTPOE++ PDs and IEEE 802.3bt-compliant PDs.
