It is offered in both push-pull and opendrain 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 lowline output is used as a second interrupt line to indicate a fall in VCC (1.02 × VRST).
