Rochester Electronics PMIC - Supervisors DS1831AS

The DS1831AS is a multisupply monitor and reset supervisor designed to monitor up to four system voltages, specifically 5V and 3.3V supplies, along with two additional user-configurable voltage monitors. It operates by drawing power from the higher of the two input voltages, ensuring reliable functionality. The device features a pushbutton reset for manual override and maintains reset signals for configurable time delays of 10ms, 100ms, or 1s, allowing for system stabilization during power transients. The DS1831AS includes precision temperature-compensated voltage references and voltage sensors, making it suitable for systems that require accurate monitoring of multiple power supplies. It operates within a temperature range of -40°C to +85°C and is available in a 16-pin SOIC package. The device is particularly useful in applications where power supply reliability is critical, providing alerts during out-of-tolerance conditions and ensuring proper system reset behavior.
