Power management IC (PMIC) supervisors are integrated circuits that selectively apply voltages or current to components, allowing the system to reset and protect circuits as needed. The LM3724EM5-3.08/NOPB is a PMIC supervisor, specifically designed to monitor and control input power levels with a preset threshold.

The LM3724EM5-3.08/NOPB has a variety of applications, including power distribution, system monitoring, and reset of multiple-input supplies. It readily monitors single-supply voltages and dual-ground supplies, as well as providing an undervoltage warning signal that is qualified by the user-selectable reset threshold. Additionally, it is designed with an operational current of 2.5µA maximum, making it an optimal choice for monitoring supplies in remote locations.

The design of the LM3724EM5-3.08/NOPB begins with the needs of the application, primarily monitoring system power in a variety of applications. The supervisor works by comparing the voltage of the system against preset thresholds. If the voltage is within the preset threshold, an output signal is asserted, allowing power to be supplied to the system. If the voltage is outside the preset thresholds, an output signal disengages, preventing power being supplied to the system.

The LM3724EM5-3.08/NOPB\'s threshold voltages are user selectable and the operating range is specified to the setpoint temperature. This ensures that the supervisor will accurately detect and respond to an under or over voltage condition. Additionally, the LM3724EM5-3.08/NOPB\'s undervoltage warning signal is qualified by the user-selectable reset threshold, thus alerting the system to any risk of power fluctuations.

The reset output of the LM3724EM5-3.08/NOPB is capable of sinking or sourcing current, depending on the voltage input. This output can be used to reset a microcontroller or other electronic circuitry that is connected to the supervisor. The reset output is capable of sinking up to 5mA, making it ideal for resetting small loads. It also features an active pull-up input pin, providing the flexibility to configure the supervisor for either active-high or active-low reset conditions.

The LM3724EM5-3.08/NOPB is a highly integrated and versatile supervisor, with several integrated features. It has a built-in voltage reference that is accurate to ±0.7% over temperature, and its reset output is qualified by the user selectable reset threshold. The LM3724EM5-3.08/NOPB also includes open-drain output and overvoltage delay circuitry. All of these features make it an ideal choice for automatically monitoring and controlling input power levels.
