Product Overview
LT4275 is a LTPoE++/PoE+/PoE PD controller. This device is IEEE 802.3at compliant. This device internal charge pump provides an N-channel MOSFET solution, eliminating a larger and more costly P-channel MOSFET. A low RDS(ON) MOSFET also maximizes power delivery and efficiency, reduces power and heat dissipation, and eases thermal design. Start-up inrush current is adjustable with an external capacitor. It also includes a power good output, on-board signature resistor, under voltage lockout, and thermal protection. This device drives a single opto-coupler to indicate the power level of the attached PSE. Pin-selectable support for non-standard low voltage operation is provided. It is widely used in application such as high power wireless data systems, outdoor security camera equipment, commercial and public information displays, high temperature industrial applications etc.
- Operating input voltage (VPORT) is 23V to 60V
- 100V absolute maximum input voltage
- Over temperature protection
- Integrated signature resistor
- Programmable aux power support as low as 9V
- Optional support of non-standard low voltage PoE
- Supply current is 2mA maximum at (VPORT = HSSRC = 57V)
- AUX threshold is 6.3V typical
- Operating temperature is -40°C to 85°C, maximum PD power is 25.5W
- Packaging style is 10-lead plastic MSOP
