The LTC2937 is a 6-channel power supply sequencer and voltage supervisor. Supplies are enabled or disabled with precise user controlled order and time spacing. To detect power supply output faults during sequencing and monitoring, the LTC2937 accurately monitors supply turn-on/-off delays and output voltage levels. In the event of a fault, response actions include complete power supply shutdown and optional restarts. Root cause of power faults are logged to EEPROM. For systems with high supply count, a simple single wire connection between multiple LTC2937 devices allows sequencing expansion to 300 supplies. After successful sequencing and supply voltage stabilization, the reset output pulls high to initiate microprocessor or other system activity. To accommodate supply margin testing, the reset output can be disabled. Upon supply turn-off, integrated current sources are available as needed to discharge slowly decaying supplies. Configuration EEPROM supports autonomous operation without software.
