LM3709 Datasheet Microprocessor Supervisor

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LM3708/LM3709 Microprocessor Supervisory Circuits with Low Line Output, Manual Reset and Watchdog Timer June 2002 LM3708/LM3709 Microprocessor Supervisory Circuits with Low Line Output, Manual Reset and Watchdog Timer.

This datasheet includes multiple variants, all published together in a single manufacturer document.

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.

Built-in

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.
