TPS23753APWR General Description

The TPS23753APWR is a Power over Ethernet (PoE) controller designed by Texas Instruments. It operates within a wide input voltage range, typically 36V to 57V, making it suitable for various PoE applications. This device integrates both the IEEE 802.3at-compliant PoE interface and a DC-DC controller, enabling efficient power delivery to powered devices (PDs). Its high level of integration reduces external component count and board space, facilitating compact designs. The TPS23753APWR features programmable current limit and classification, allowing customization for different PD requirements. It supports various protection features like overcurrent, overvoltage, and overtemperature protection, ensuring system reliability and durability. With its advanced features and robust protection mechanisms, the TPS23753APWR offers a reliable solution for implementing PoE in a wide range of applications, including IP cameras, wireless access points, and VoIP phones

Arrived in good time. This is either an older chipset or the USB serial is not the best as for the first time in a year of buying and using these I had to change the flash frequency from 80 to 40Mhz.Uploading at 80 Mhz puts the chip into a permanent start restart state. True on 3 of 50 modules. I have not tried all otherwise all packets will be opened.
