Power management integrated circuits (PMIC) play a very important role in electronic systems, powering, controlling and maintaining the electronic devices. The LM3710XQMMX-308/NOPB is one such kind of a power management IC, falling under the category of Supervisor PMICs. It is specifically designed for providing reliable power supply monitoring to reset systems in the event of abnormally low or high voltage.

Application Field: The LM3710XQMMX-308/NOPB is an ideal choice for providing reliable monitoring of power supplies and resetting of systems in the event of insufficient power. It is mainlyused in industrial, automotive and aerospace systems, that must remain robust to withstand extreme weather fluctuations and shock. The LM3710XQMMX-308/NOPB is also ideal for use in electrical and electronic systems, where reliable resetting of the system is desired. This power management IC provides reliable resetting during electric pulses caused by power outages, load transients, or electric surges.

Working Principle: The LM3710XQMMX-308/NOPB is a voltage supervisor PMIC that uses an integrated comparator to sense power supply voltage. It is programmed using a resistor divider set to detect a preset threshold voltage level, depending on the user\'s requirements. When the input voltage drops below or rises above the threshold, the comparator triggers a logic output, signalling an out-of- allowable voltage condition. The reset output remains active until the input voltage returns to within an acceptable voltage range. The LM3710XQMMX-308/NOPB uses an open drain output, eliminating cross-currents during the voltage tests. It also features an enable input that helps in disabling the power monitoring circuit to save power.

The LM3710XQMMX-308/NOPB is a low-power supervisor IC, requiring only 4 uA quiescent current. It features a wide operating temperature range, from -40A to +125A. Its other features include an out-of-allowable voltage flag, voltage supervisor and reset generator in a single device, low power consumption, and an active-low power-on reset output. The LM3710XQMMX-308/NOPB provides users with a robust power management IC, capable of detecting abnormal power supply conditions in industrial, automotive and aerospace applications.
