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.

Demonstration circuit 2313A showcases the LTC2937, a programmable six channel power supply sequencer and voltage supervisor. The LTC2937 provides flexible sequence control for up to six power supplies. It enables and disables the supplies with configurable sequence order and time delays, monitors the supplies for power-up and power-down time, and for overvoltage and undervoltage. It cooperates with other LTC2937 parts in the system to coordinate power sequencing activities. It provides flexible fault response to autonomously supervise the power supplies, and powerful debug tools to diagnose any problem that causes a powersupply fault. It holds configuration in non-volatile EEPROM for completely automatic power system supervision. The DC2313A board demonstrates the powerful features of the LTC2937 using six onboard LDO voltage regulators, or by controlling an optional, externally-powered DC1361 board (an 8-channel power supply board). Multiple DC2313A boards can also share timing and sequencing signals to supervise more than six regulated supplies in a coordinated manner. The DC2313A connects to a PC through the DC1613 USBto-I2C/SMBus/PMBus Controller. This connection enables the LTpowerPlayâ„¢ software, to have complete control over the LTC2937 through the convenient LTpowerPlay GUI. The GUI allows control over all of the LTC2937 registers, and visibility into the status of the part in real time, and it works with Linear Technology demo boards as well as custom boards with an I2C interface.
