    LTC®2937 是一款 6 通道电源排序器和电压监控器。利用精准的用户控制次序和时间间隔来使能或停用电源。为了在排序和监视过程中检测电源输出故障,LTC2937 可准确地监视电源的接通 / 关断延迟和输出电压电平。如果发生故障,响应动作包括电源完全关断和可任选的重启。电源故障的根本原因被记录到 EEPROM 中。对于那些具有很多电源的系统,在多个 LTC2937 器件之间采用简单的单线式连接可将排序扩展到 300 个电源。在实现成功排序和电源电压稳定之后,复位输出被拉至高电平以启动微处理器或其他的系统运作。如欲提供电源裕度测试,则可停用复位输出。一旦电源关断,则可根据需要使用集成型电流源来对缓慢衰减的电源进行放电。配置 EEPROM 支持自主型操作,并不需要借助软件。

    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.

    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.
