LM3702/LM3703 microprocessor supervisory circuits with low line output and manual reset
The LM3702 and LM3703 are microprocessor supervisory circuits that monitor power supplies and battery‑controlled functions. They provide reset functions during power‑up, power‑down, and brown‑out conditions, a manual‑reset input, and a low‑line output that warns of early power failure. The devices are offered in a 9‑bump micro SMD package and can be customized for reset threshold voltages between 2.2 V and 5.0 V.
The datasheet includes electrical characteristics, absolute maximum ratings, ordering information, typical performance graphs, and physical dimensions. It also lists application examples such as embedded controllers, automotive systems, and critical power‑monitoring circuits, along with contact information for National Semiconductor support centers worldwide.
