LTC2937IUHE#PBF

Power Supply Controllers, Monitors Overview

The LTC2937IUHE#PBF is a programmable six-channel power supply sequencer and voltage supervisor manufactured by Analog Devices Inc. It provides flexible sequence control for up to six power supplies, enabling and disabling them with configurable order and time delays. The device monitors power-up and power-down times, as well as overvoltage and undervoltage conditions. It features non-volatile EEPROM storage for configuration retention and supports coordination with other LTC2937 parts in the system.

Power Supply Controllers, Monitors Feature Summary

• Provides flexible sequence control for up to six power supplies with configurable order and time delays
• Monitors power supply status including power-up/down times and overvoltage/undervoltage conditions
• Stores configuration in non-volatile EEPROM for automatic power system supervision
• Cooperates with other LTC2937 components to coordinate power sequencing activities

Power Supply Controllers, Monitors Applications

• Multi-rail power supply sequencing systems
• Voltage supervision for critical power rails
• System startup and shutdown sequence management
• Fault diagnosis in power distribution networks

Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix #PBF indicates tube packaging when ordering. Confirm the I grade temperature range matches your application requirements. Ensure the 28-QFN package footprint aligns with your PCB design. Check current availability status as supply levels may vary. Validate that the programming board DC2347A is available if initial configuration is required.

Power Supply Controllers, Monitors Selection Notes

Select this component when precise control over multiple power rail sequencing is required. The EEPROM feature allows for persistent configuration without external memory. Consider the I grade rating for industrial temperature applications. Evaluate the need for multi-device coordination if complex system architectures are involved. Verify compatibility with existing voltage supervisors in the design.

Power Supply Controllers, Monitors Part Context

The LTC2937 belongs to Analog Devices' family of power management ICs focused on supervisory and sequencing functions. It is designed for systems requiring robust power management and fault detection. The device complements other PMIC solutions by handling complex startup sequences autonomously. It is part of a broader ecosystem including demonstration circuits like DC2313A for evaluation purposes.

Power Supply Controllers, Monitors Replacement Considerations

Direct substitutes include other variants within the LTC2937 family such as LTC2937CUHE#PBF or LTC2937HUHE#PBF, which offer different temperature grades but identical functionality. Verify pinout and electrical specifications match before substitution. No cross-family replacements are officially documented.
