The TPS23753APWR is an integrated hot swap voltage controller, Power over Ethernet (PoE) interface, and isolated converter controller from Texas Instruments. This device features integrated circuit protection, such as current limiting, over-voltage protection, and over temperature protection. It also allows for automatic detection of up to 6 different IEEE 802.3af classifications, and pin-selectable IEEE 802.3at classifications. This hot-swap controller also features programmable firmware, adjustable voltage levels, and external resistor voltage programming for various classes of PoE implementations. This device is ideal for systems requiring efficient power management and systematic control.
