LTC2937CUHE#TRPBF

Power Supply Controllers, Monitors Overview

The LTC2937CUHE#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 temperature range of -40°C to +85°C and is housed in a 28-lead QFN package measuring 5mm by 6mm.

Power Supply Controllers, Monitors Feature Summary

• Configurable sequence order and time delays for up to six power supplies
• Non-volatile EEPROM storage for configuration retention
• Integrated fault response for autonomous power supply supervision

Power Supply Controllers, Monitors Applications

• Multi-rail server power systems
