LM3702/LM3703

Microprocessor Supervisory Circuits with Low Line

Output and Manual Reset

General Description

The LM3702/LM3703 series of microprocessor supervisory

circuits provide the maximum flexibility for monitoring power

supplies and battery controlled functions in systems without

backup batteries. The LM3702/LM3703 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.
