NCV33164D-5R2 is a device specifically designed for portable systems where low quiescent current and small size components are important. It is a supervisor and power management integrated circuit (PMIC) that offers a wide range of features to meet the demands of portable systems, especially in terms of power consumption. It is widely used in many fields, such as industrial, automotive and consumer electronics.

Overview of NCV33164D-5R2
NCV33164D-5R2 is a dual reset supervisor and power management integrated circuit (PMIC), which includes two reset outputs and one watchdog timer output. The device incorporates various features, such as low quiescent current, power-on reset, voltage tracking, and adjustable reset thresholds. It also offers a wide range of features to meet the demands of portable systems, especially in terms of power consumption. The reset time can be adjustable and the reset threshold can be programmed from 1.71V to 4.25V. The device is compatible with all standard logic voltage threshold.

Application Field of NCV33164D-5R2
NCV33164D-5R2 is suitable for many industrial applications, such as portable equipment and automotive systems. It is also used in consumer electronics applications, such as multimedia players, digital cameras and portable navigation systems. It is a popular choice for supplying reset signals and power management in handheld devices, which utilize low voltage operation and contain numerous integrated circuits and other components.

Working Principle of NCV33164D-5R2
The NCV33164D-5R2 works by monitoring the power supply voltage levels and providing a reset signal when the voltage drops below a specified threshold. The device includes two reset outputs, each operating independently of the other, as well as a watchdog timer output. When the supply voltage drops below the reset threshold, the device generates and outputs a reset signal that is asserted until the supply voltage returns to the specified level.The device also offers an adjustable reset time that can be used to ensure that the reset signal is generated for the required period of time.

The device includes an internal comparator that monitors the power supply voltage and triggers the reset output when the voltage drops below the adjustable reset threshold. The adjustable threshold can be programmed from 1.71V to 4.25V, allowing the reset threshold to be tuned to meet the needs of the particular application. Once the threshold has been exceeded, the reset signal is asserted until either the voltage returns to the specified level or the reset time has elapsed.

In addition to its reset and power supply monitoring features, the NCV33164D-5R2 also features a watchdog timer output. This output can be used to generate a signal after a specified period of time, ensuring that the application is still running correctly.The device also features an adjustable debounce time that can be used to de-bounce input signals, eliminating false reset assertions.

In summary, the NCV33164D-5R2 is a PMIC supervisor that offers a wide range of features to meet the demands of portable systems, especially in terms of power consumption. It allows for adjustable reset thresholds as well as a watchdog timer output, making it suitable for a variety of applications.
