The DS1834S from Analog Devices/Maxim Integrated is a dual voltage supervisor designed to monitor both 3.3V and 5V power supply conditions. It features a precision temperature-compensated voltage reference and comparator circuit to detect out-of-tolerance conditions, asserting a reset signal when necessary. The device also includes an internally debounced pushbutton input for system override.
This supervisor is ideal for systems operating with dual power supplies, ensuring system stability during power transients. It maintains reset for approximately 350 ms after VCC returns to an in-tolerance condition, reducing the need for discrete components. The DS1834S operates over a temperature range of -40°C to +85°C and is available in an 8-pin SOIC package.
Key electrical characteristics include monitoring two voltages (3.3V and 5V) with an active low reset output. The output type is open drain or open collector. The device draws internal operating current from the higher of the two input voltages.
