The LTC2928CUHF#PBF is a sophisticated power supply management IC designed by Linear Technology to control and monitor up to four power supply voltages in complex systems. This versatile component ensures that multiple power supplies are sequenced in a user-defined order, providing a reliable and efficient power-up and power-down sequence for digital systems like FPGAs, DSPs, and microprocessors.

Key Features

• Power Sequencing: The LTC2928CUHF#PBF offers programmable power-up and power-down sequencing, which is crucial for systems requiring specific voltage ramp-up and ramp-down procedures to ensure proper operation and to avoid damage to sensitive components.
• Multiple Voltage Monitoring: It can monitor up to four power supply outputs, ensuring that all supply voltages are within the acceptable thresholds before enabling the subsequent power supply, thereby enhancing system reliability.
• Flexible Configuration: Configuration is made easy and flexible through the use of external resistors or the I²C/SMBus interface, allowing designers to tailor the power sequence to their specific needs without the need for hardware changes.
• Compact Package: Packaged in a compact QFN-38 (5mm x 7mm), the LTC2928CUHF#PBF is designed for space-constrained applications, providing powerful control in a small footprint.
• Adjustable Time Delays: Time delays between the enable signals of different supplies are adjustable, enabling designers to set the precise timing required for their systems.
