Product Overview
LT®4294 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. This 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. This also includes a power good output, on-board signature resistor, undervoltage lockout, and thermal protection. Start-up inrush current is adjustable with an external capacitor. Pin-for-pin compatibility with the LT4275 family of PD interface controllers enables easy migration between LTPoE++ PDs and IEEE 802.3btcompliant PDs. Typical applications are high power wireless data systems, outdoor security camera equipment, commercial and public information displays, high temperature industrial applications.
- Auxiliary power override is supported as low as 9V with the AUX pin
- 5-event classification sensing, superior surge protection
- Overtemperature protection, integrated signature resistor
- External hot swap N-channel MOSFET for lowest power dissipation and highest system efficiency
- Configurable aux power support as low as 9V
- Easy migration between LTPoE++® PDs and IEEE 802.3bt PDs
- VPORT aux mode range from 8 to 60V (at VPORT pin, AUX
VAUXT, TA=25°C) - Supply current is 2mA max (VVPORT=VHSSRC=57V, TA=25°C)
- 10-lead plastic MSOP package
- Temperature rating range from -40°C to 85°C
