LTC2937MPUHE#TRPBF

Power Supply Controllers, Monitors Overview

The LTC2937MPUHE#TRPBF 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. Configuration data is stored in non-volatile EEPROM for automatic supervision. It operates within a specified temperature range and supports communication with other system components.

Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix 'MPUHE' against official Analog Devices documentation to confirm package type and tape/reel specifications. Ensure compatibility with existing board layouts and firmware requirements before procurement. Confirm availability status through authorized distributors as supply levels may vary.

Power Supply Controllers, Monitors Selection Notes

Select this component when precise timing control for multiple voltage rails is required. Consider the eight-pin QFN package constraints and thermal performance. Evaluate if the six-channel capacity meets system needs or if fewer channels are sufficient. Verify EEPROM retention requirements for persistent configuration settings.

Power Supply Controllers, Monitors Part Context

This part belongs to the LTC2937 family of power supervisors. It is designed for applications requiring autonomous power system management without microcontroller intervention. The device integrates sequencing logic and monitoring capabilities into a single compact solution, reducing bill-of-materials complexity compared to discrete implementations.

Power Supply Controllers, Monitors Replacement Considerations

Check Analog Devices documentation for direct pin-compatible alternatives within the LTC293x series. Verify that any substitute maintains identical EEPROM programming interfaces and channel counts. Cross-reference package dimensions and thermal characteristics to ensure mechanical fit.
