LM3703 Microprocessor Supervisor

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,.

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. n n n n n n n n No external components required Manual-Reset input RESET (LM3702) or RESET (LM3703) outputs Precision supply voltage monitor Factory programmable Reset Timeout Delay Available in micro SMD package for minimum foot.
