LM3708/LM3709
Microprocessor Supervisory Circuits with Low Line
Output, Manual Reset and Watchdog Timer
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 features include the following:
Reset: Reset is asserted during power-up, power-down, and
brownout conditions. RESET is guaranteed down to V
CC 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 P’s output lines for activity. If no output transition occurs
during the watchdog timeout period, reset is activated.
