DC2313A: 6 Ch. Seq. Controller, 6 ~ 14V in

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 power supply 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 USB-to-I2C/SMBus/PMBus Controller. This connection enables the LTpowerPlay™ 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.
