LM5070MTC-50 Datasheet PDF - TI

The LM5070MTC-50 is a Power Interface Port and Pulse Width Modulation (PWM) Controller provides a complete integrated solution for Powered Devices (PD) that connect into Power over Ethernet (PoE) systems. The LM5070 integrates a 80V, 400mA line connection switch and associated control for a fully IEEE 802.3af compliant interface with a full featured current-mode pulse width modulator dc-dc converter. All power sequencing requirements between the controller interface and switch mode power supply (SMPS) are integrated into the IC.

● Fully compliant 802.3af Power interface port

● Programmable inrush current limit

● Detection resistor disconnect function

● Programmable classification current

● Programmable under-voltage lockout with programmable hysteresis

● Thermal shutdown protection

● Current mode pulse width modulator

● Supports both isolated and non-isolated applications

● Error amplifier and reference for non-isolated applications

● Programmable oscillator frequency

● Programmable soft-start

● 800mA Peak gate driver

● Green product and no Sb/Br

●Device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
