Understanding TPS23753APWR

The TPS23753APWR is a powerful and adaptable integrated circuit that caters to a variety of power requirements. Here’s a breakdown of its key features:

PoE Support

The IEEE 802.3at standard is followed by the TPS23753APWR, making it compatible with Type 1 PoE devices. This implies it can get up to 13 watts of electricity through Ethernet. The IEEE 802.3at standard is a superset of the older IEEE 802.3af standard, giving increased Power over Ethernet features.

Input Voltage Options

This gadget provides input voltage management versatility. It enables different input-voltage ORing settings, such as the external adapter preference,  highest voltage, and PoE preference. Because of its versatility, it is appropriate for a wide range of applications.

External Detection Signature

An external detection signature pin has been incorporated into the TPS23753APWR, and it performs a dual role in the design. Either for external detection or to disable the internal hot-swap MOSFET, you can use it in either capacity. You have complete control over the flow of power thanks to this feature, which enables you to turn off the PoE function whenever it is required.

Classification Flexibility

Using just one resistor, the TPS23753APWR’s categorization can be quickly and simply changed to any of the various types that have been described. This makes the process of setting up and customizing the program to meet your particular requirements much simpler.

DC-DC Controller

The TPS23753APWR’s DC-DC controller uses a bootstrap start-up approach with an internal switching current source. This design has various advantages, including cycle overload fault protection without a pull-up resistor’s persistent power loss.


The TPS23753APWR’s programmable oscillator can be synchronized to a higher-frequency external timing reference, allowing you to precisely regulate the switching frequency in your power conversion circuit.


Equipped with a robust 100-V, 0.7-Ω hot-swap MOSFET, this device ensures reliable and efficient power transfer while protecting against overloads and voltage spikes.

Package and Temperature Range

The TPS23753APWR comes in a 14-pin TSSOP package, making it ideal for space-constrained applications. It can function in temperatures ranging from -40°C to 125°C, assuring its dependability in a variety of situations.

ESD Protection

The device features enhanced ESD ride-through capability and system-level ESD protection of 15 kV and 8 kV. This makes it robust and reliable in harsh operating conditions.
