The LM3710/LM3711 series of microprocessor supervisory circuits provide the maximum flexibility for monitoring power supplies and battery controlled functions in systems without backup batteries. The LM3710/LM3711 series are available in VSSOP-10 and 9-bump DSBGA packages.
Built-in features include the following:
Reset: Reset is asserted during power-up, power-down, and brownout conditions. RESET is ensured down to VCC of 1.0V.
Manual Reset Input: An input that asserts reset when pulled low.
Power-Fail Input: A 1.225V threshold detector for power fail warning, or to monitor a power supply other than VCC.
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 output transition occurs during the watchdog timeout period, reset is activated.
