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. Power-Fail Input: A 1.225V threshold detector for power fail warning, or to monitor a power supply other than VCC. Watchdog Timer: The WDI (Watchdog Input) monitors one of the µP’s output lines for activity. If no output transitio...

Voltage Supervisor
The LM3704 is a feature-rich, easy-to-use voltage supervisor. 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). Device Information(1) PART NUMBER PACKAGE BODY SIZE (NOM) LM3704 VSSOP (10) 3.00 mm × 3.00 mm (1) For all available packages, see the orderable addendum at the end of the data sheet.
