TPS2383BPMR

The Texas Instruments TPS2383BPMR is an integrated circuit designed as a Power Sourcing Equipment (PSE) controller for Power Over Ethernet (PoE) applications. This device features 8 channels, enabling it to manage power delivery to multiple PoE-enabled devices.

Key electrical specifications include an operating voltage range of 44V to 57V and a power rating of 15.4W. The controller supports IEEE 802.3af standards and offers features such as capacitive detection for legacy loads, power classification, and controlled ramp-up/down for EMI reduction. It also includes current management for charging bulk capacitance, an electronic circuit breaker, and fault detection capabilities.

The TPS2383BPMR provides 12-bit acquisition for port current and voltage, along with a standard slave I2C serial interface for communication. It offers 5-bit serial address selectability and supports opto-coupler compatible SDA and SCL lines for system ground isolation. A dual-color LED driver is integrated for port status indication, and a hardware FAULT interrupt is available.

Packaged in a 64-LQFP (10x10) format, this component is designed for surface mount installation. It operates within a temperature range of -40°C to 85°C.
