LTC2970 - 双通道 I2C 电源监视器和裕度调节控制器
LTC®2970 是一款双通道电源监视器和裕度调节控制器，具有一个与 SMBus 相兼容的I2C 总线接口。一个低漂移、片内基准和 14 位 ΔΣ A/D 转换器提供了电源电压、负载电流或内部芯片温度的精准测量。故障管理功能允许针对可配置过压和欠压故障条件来确定 ALERT。两个电压缓冲、8 位 IDAC 实现了 DC/DC 转换器输出电压的高准确度设置。通过配置，可以使这些 IDAC 采用 ADC 来自动地把电源保持于期望的电压值。LTC2970-1 增加了一种跟踪功能，该功能可用于以一种受控的方式来接通或关断多个电源。 通过 ASEL0 和 ASEL1 引脚的搭接，可将总线地址设定为 9 种可能组合中的一种。LTC2970 / LTC2970-1 采用 24 引脚、4mm x 5mm QFN 封装。
