LM3704中文资料具有电源故障输入、低电平线路输出和手动复位功能的电 压监控器和复位 IC数据手册TI规格书

描述 Description

The LM3704 is a feature-rich, easy-to-use voltage supervisor. It is offered in both push-pull and open-drain configuration with a tight 2% accuracy over temperature.

The LM3704 features include a manual reset, low-line output, and power-fail input detection. The power-fail input allows for a configurable second rail to be monitored helping detect upstream failures. The low-line output is used as a second interrupt line to indicate a fall in VCC (1.02 × VRST).
