描述
The LTC1728 is functionally identical to the LTC1727 without the individual monitor outputs.
The RST output is guaranteed to be in the correct state for V CC5 /V CC25 /V CC18 or V CC3 down to 1V. The LTC1727/LTC1728 may also be configured to monitor any one or two V CC inputs instead of three, depending on system requirements.
Very low (10μA typical) supply current makes the LTC1727/LTC1728 ideal for power conscious systems.
The LTC1727 is available in an 8-lead MSOP or SO package and the LTC1728 is available in a 5-lead SOT-23 package.
