The DS1813-5 is a PMIC, or power management integrated circuit, also known as a supervisor. A supervisor is an electronic circuit that monitors the power supply and voltage levels in a device or system, ensuring that the parameters are within normal operating range. It also provides additional protection against overvoltage and overcurrent conditions, which can otherwise damage the system.The DS1813-5 is a dual power supervisor that integrates two identical power-fail (PWR-FAIL) outputs. Each output monitors two independent input power rails, allowing customers to monitor power levels in multiple power supplies. The power management IC includes a precision reference voltage with two adjustable voltage thresholds; when one of these voltages is exceeded, an output is immediately activated and an interrupt signal is sent to the system.The DS1813-5 also includes a low-power-mode circuit to protect against power rail disruption. In this mode, the circuit reduces the power consumption of the IC to 0.01 Watts, allowing the system to continue functioning when the power supply experiences momentary dips or short-term outages. The integrated time-out circuit prevents the IC from staying in this low-power-state for too long, protecting against permanent power failures.The DS1813-5 supports a range of adjustable threshold voltages, from 1.3V to 4.5V. The IC also provides a maximum delay time of 76ms for the power-fail outputs and a maximum reset delay time of 560ms. This helps to ensure that the IC responds quickly to any changes in power levels.The DS1813-5 is suitable for a wide range of applications, including industrial, medical and automotive equipment. It is most commonly used to protect sensitive electronics and equipment from excessive levels of power. The IC provides protection to all types of loads, and is optimized for quick response times, low power consumption, and accurate monitoring of multiple power supplies.The DS1813-5 was designed with reliability in mind. It is built using advanced semiconductor processes, making it resistant to voltage spikes, transient overvoltage and other environmental stressors. The IC is rated for an operating temperature range of -40°C to +105°C, and is suitable for use in harsh industrial and automotive environments.The DS1813-5 is a reliable, cost-effective power management IC that makes it easy to monitor multiple power supplies and protect sensitive equipment from overcurrent and overvoltage conditions. By integrating two identical power-fail outputs, the IC can provide protection against momentary power failures and other power-related disruptions. It is a versatile, reliable solution for a wide range of applications, making it an ideal choice for industrial, medical, and automotive applications.
