    产品详情

    The DC2347A contains only those functions necessary to safely program and verify the LTC2937 configuration EEPROM. It serves no other purpose. The DC2347A holds the LTC2937 in a clamshell socket for convenient access and replacement of parts. The LTpowerPlay™ GUI software, running on a PC, provides a simple interface to program and verify the EEPROM with a user supplied configuration.

    产品详情

    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.
