LM3709 - Microprocessor Supervisor

Download the LM3709 datasheet PDF. This datasheet also covers the LM3708 variant, as both devices belong to the same microprocessor supervisor family and are provided as variant models within a single manufacturer datasheet.

General 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.

Key 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.
