LTC2928IG#PBF - Power Supply Tracking Controller
The LTC2928IG#PBF is a sophisticated power supply tracking controller designed by Linear Technology, a leader in the design and manufacture of high-performance analog integrated circuits. This component is engineered to manage and sequence multiple power supplies in complex systems, ensuring that voltage levels ramp up and down in a controlled manner. By providing precise tracking capabilities, the LTC2928IG#PBF is an essential device for systems that require reliable power sequencing, such as servers, telecommunications equipment, and industrial control systems.
The LTC2928IG#PBF is capable of independently controlling up to four power supplies. Each of the four channels can be configured to track one another or a common signal, providing flexibility in managing different power-up and power-down sequences. The device also supports ratiometric, coincident, or even non-monotonic tracking, allowing for a wide range of power supply management strategies.
One of the key features of the LTC2928IG#PBF is its programmability. Designers can set the sequencing behavior through external resistors or via the I²C/SMBus-compatible serial interface, which offers a more precise and flexible approach to power management. This level of programmability ensures that the LTC2928IG#PBF can be tailored to meet the specific needs of a variety of applications.
The LTC2928IG#PBF operates from a supply voltage ranging from 2.7V to 14V, making it suitable for a broad spectrum of power systems. It also includes built-in fault protection features such as overvoltage and undervoltage monitoring, which help to safeguard the system against power anomalies. With its robust design, the LTC2928IG#PBF is offered in a durable 28-lead SSOP package that can withstand industrial temperature ranges from -40°C to 85°C.
For designers and engineers looking for a reliable solution to manage complex power supply sequences, the LTC2928IG#PBF from Linear Technology is a high-performance option that combines versatility, precision, and protection in a single integrated circuit.
