The DS1831+ from Analog Devices (formerly Maxim Integrated) is a versatile multi-voltage supervisor IC. It is engineered to monitor up to four system voltages, including dedicated 5V and 3.3V supplies, along with two additional user-configurable voltage monitors. This device is ideal for systems operating with multiple power rails, ensuring reliable operation during power transients.
The DS1831+ features integrated power-on reset for both 5V and 3.3V supplies. It also includes a pushbutton reset input for manual system override. The reset hold time is user-configurable, offering options of 10ms, 100ms, or 1 second to meet specific system requirements. The internal power for the device is drawn from the higher of the 5V or 3.3V input, requiring at least one input to be above 1V for operation.
This supervisor IC incorporates a precision, temperature-compensated voltage reference and sensor, contributing to its accurate monitoring capabilities. The DS1831+ is available in a 16-pin DIP package, suitable for through-hole mounting. Its operating temperature range is -40°C to +85°C, making it suitable for a variety of environmental conditions.
