Linear Technology LTC2928IUHF - Power Supply Manager

The LTC2928IUHF from Linear Technology is a sophisticated power supply manager designed to control and monitor up to four power supply voltages in a system. This component ensures that the power supplies are sequenced in a user-defined order, both on power-up and power-down, enhancing the reliability and safety of the overall system. With its precision monitoring capabilities, the LTC2928IUHF provides real-time feedback on the status of the power supplies, making it an essential component for complex electronic systems.

Key Features

• Voltage Monitoring: The LTC2928IUHF accurately monitors the voltage levels of up to four power supplies, ensuring they remain within the specified thresholds for safe operation.
• Programmable Sequencing: Users can program the sequence of voltage ramp-up and ramp-down, which is critical for systems that require a specific power-up or power-down order to prevent damage or data corruption.
• Adjustable Timing: The timing of each power supply's enable signal can be adjusted using external components, providing flexibility to meet various system requirements.
• Power Good Outputs: The device offers 'power good' outputs that signal when each power supply has stabilized at its correct operating voltage, enabling downstream logic to proceed with confidence.
• Compact Package: Housed in a 38-lead QFN package, the LTC2928IUHF saves valuable board space and is suitable for space-constrained applications.
