The UCC5640PW28 is part of a family of Universal Interface Constant Current Regulator (UCC) devices capable of sourcing and sinking constant current at both logic level and industrial logic levels (Types A and B ). This device is part of Texas Instruments’ single-channel signal termination family. It\'s specifically designed to prevent data errors due to reflections of digital signals in an often-crowded environment.

The UCC5640PW28 is a two-channel, unidirectional, logic-level and industrial logic-level signal terminator. It can source or sink a constant current of 1.5mA for standard logic and up to 5mA for industrial logic level in either direction. This feature allows the device to be used as a terminating resistor network, eliminating the need for multiple discrete components in the system.

The UCC5640PW28 operates from a single 3.3-V to 5.5-V supply, making it compatible with a wide range of supply voltages and systems. Additionally, the device includes a low-current sleep mode for power conservation when not in use, reducing power consumption by up to 80%.

The UCC5640PW28 is designed to work in both unidirectional and bidirectional applications. In unidirectional applications, constant current is only sourced or sunk in one direction, while in bidirectional applications the constant current flows in both directions.

The UCC5640PW28 is capable of offering reliable 10BASE-T/100BASE-TX/1000BASE-T and low-frequency (100KHz) Ethernet applications. For 10BASE-T applications, it can source or sink current up to 2.8mA for a short duration at speeds of up to 125MHz. It also offers robust industrial logic termination, with an option for high-impedance open circuit operation, allowing the device to be used in low-voltage applications.

The UCC5640PW28\'s working principle is simple and easy to understand. The device acts as an active current-limiting load, handling irregularities in the data transmission environment by limiting the amount of current that can flow in either direction. This helps reduce electrical noise and unwanted reflections in the system. The device can also be configured as either an output buffer or an input buffer.

In addition, the UCC5640PW28 is designed to offer excellent noise immunity and EMI (electromagnetic interference) capability. Its shielded metal construction shields the device from external noise and provides good EMI protection. Its robust design also ensures a low power-to-noise ratio, making it ideal for installations in noisy environments.

The UCC5640PW28 is an excellent choice for applications where noise, EMI, and power conservation are all key performance criteria. This constant current source/sink is designed to provide reliable data transmission over noisy communication channels and is well-suited for power-sensitive, low-voltage applications. With its simple working principle and low power consumption, the UCC5640PW28 is the perfect choice for a wide range of interface applications.
