LM3709 - Microprocessor Supervisor

Download the LM3709 datasheet PDF (LM3708 included). The manufacturer datasheet provides complete specifications, pinout details, electrical characteristics, and typical applications for microprocessor supervisor.

Description

The LM3708/LM3709 series of microprocessor supervisory circuits provide the maximum flexibility for monitoring power supplies and battery controlled functions in systems without backup batteries.

The LM3708/LM3709 series are available in a 9-bump micro SMD package.

Features

  • include the following: Reset: Reset is asserted during power-up, power-down, and brownout conditions. RESET is guaranteed down to VCC of 1.0V. Manual Reset Input: An input that asserts reset when pulled low. Low Line Output: This early power failure warning indicator goes low when the supply voltage drops to a value which is 2% higher than the reset threshold voltage. Watchdog Timer: The WDI (Watchdog Input) monitors one of the µP’s output lines for activity. If no.
