  • TPS23757PWR Application Field and Working Principle

    The TPS23757PWR is a high-efficiency, low-power, Power Over Ethernet (PoE) integrated controller from Texas Instruments. This device is ideal for mid- and high-power PoE applications. Its versatile features are adaptable to different kinds of PoE applications. It is particularly suited for applications such as IP cameras, access control systems, personal computers, IP phones and others.

    The TPS23757PWR works by receiving the Power Sourc Equipment (PSE) power that is derived from the Ethernet cable. It provides power management by combining the input power with output current to the Powered Device (PD). It also gives built-in protection against short circuits, reversed polarity, over-temperature and over-voltage conditions.

    The TPS23757PWR is also an excellent device for remote power management. It uses an automated power adjust process depending on the actual conditions at the PD. This feature ensures optimal power efficiency in different power control scenarios. It also features a power good output pin for monitoring the status of the line. This pin confirms the connection of the PD to the voltage source from the PSE.
