MN13812-N

The MN13812-N is a low-cost CMOS supervisory circuit set with an active-low push-pull reset output. They are widely used in the field of power management integrated circuits (PMICs). It consists of an internal 1.2V bandgap voltage reference, an active-low reset output, an adjustable push-pull reset output, and one or more automatic reset control pins. It also offers a wide range of features such as an adjustable reset threshold voltage, adjustable reset active-high/active-low, adjustable reset output delay time and adjustable timeout period.

The circuit offers several important features which are essential to ensure correct operation of the PMIC. First, the circuit has an adjustable reset threshold voltage which can be set by the user depending on the voltage levels to be monitored. This allows the circuit to respond to any voltage level changes and to ensure that the PMIC is always in a safe and optimal operating state. Second, the circuit has an adjustable reset active-high/active-low output which can also be set by the user. This allows the user to configure the reset output to provide the most appropriate reset signal for their specific application. Furthermore, the circuit offers an adjustable reset output delay time and an adjustable timeout period which allow the user to precisely control when and for how long the reset signal should be applied.

The working principle of this supervisory circuit set is fairly simple. It utilizes an on-chip 1.2V bandgap voltage reference which is used to monitor the input voltage and to generate the reset signal when the voltage reaches a specified level. The adjustable reset threshold voltage is configured by the user to determine at what input voltage level the reset signal should start. Then, when the voltage drops below the preset threshold, the circuit will start generating an active-low reset output and will continue to do so until the voltage returns to its normal level.

The MN13812-N offers several advantages which make it a superior choice for various PMICs applications. First, it has a low power supply current and can operate at very low voltage levels. Second, it has an adjustable reset threshold voltage which allows users to tailor the signal to their specific applications. Third, it has an adjustable reset active-high/active-low output which allows users to select the most appropriate signal for their applications. Fourth, it offers an adjustable reset output delay time and an adjustable timeout period which allow users to precisely control when and for how long the reset signal should be applied. Lastly, it has an on-chip 1.2V bandgap reference which provides an accurate and stable reference voltage.

The MN13812-N supervisory circuit set is ideal for use in power management IC applications. It has an adjustable reset threshold voltage and reset active-high/active-low output which makes it highly configurable and suitable for various applications. It also has an adjustable reset output delay time and an adjustable timeout period which allow users to precisely control the timing of the reset signal. Furthermore, it has an on-chip 1.2V bandgap voltage reference which provides an accurate and stable reference voltage for the circuit which ensures that the circuit operates as expected.
