The NCV33064P-5RA is a Quad Voltage Supervisory (QVS) device that provides four integrated regulators and 10 identical flexible input/outputs. It is part of the PMIC (Power Management Integrated Circuit) category. Its primary purpose is to monitor power supplies, ensuring that any changes in the supply voltage are within a predetermined range. This application field is typically in the automotive, communications, and industrial sectors. The NCV33064P-5RA includes four independent regulators, each with its own adjustable preset, to preserve a constant voltage level. This voltage-stabilisation process increases reliability and ensures consistent performance. The device also contains 10 identical input/outputs that can be individually configured as active-high (open drain) and active-low (push-pull), depending on the user\'s needs. Furthermore, the NCV33064P-5RA allows for an external reset delay and offers multiple comparison modes, allowing for various monitoring scenarios.An interrupt output is also provided for an autonomous controller.

The NCV33064P-5RA can function with a wide range of voltages, from 1V to 5.5V, and is temperature-compensated. The device is a surface-mountable component that only requires 1.8V to 5V to operate. This offers a degree of flexibility and simplified management during the design phase. In addition, the NCV33064P-5RA is highly integrated, meaning less components are required to operate a circuit. As such, it can lead to improved power efficiency and a decrease in design costs.

The NCV33064P-5RA is composed of 14 pins, each with a distinct role in either input or output powering. These include two pins for power inputs, four for watchdog monitor (W4), four for voltage regulator output (V4), and four for Ground connections. The W4 pins, after being supplied by the appropriate Vcc pins, monitor the operating voltage of the MCU and are activated when it exceeds the tolerance. The output of these pins is then directed to the four Voltage Regulator pins (V4) which function as four independent power supplies. Finally, Ground connections are used to complete the circuit.

The NCV33064P-5RA\'s operation is powered by a High-Voltage On-Off-Key (HV-OOK) circuit. This is an on-chip power management circuit that turns each regulator on or off at any given time without the need for external components. Once the device is powered up, it uses a series of internal logic circuits to monitor the operating voltage and ensure it remains in the desired range. It will then initiate the reset circuitry if it detects and potential changes. The reset circuitry is a simple push-pull circuit which allows the MCU to return to the predetermined safe state, protecting it from damage.

The NCV33064P-5RA is a multi-purpose and reliable power monitoring device that offers stability and accuracy in varying environments. It contains an array of features not only fulfilling basic voltage regulation tasks but also providing higher levels of protection and convenience. Beyond its practical applications for various sectors, it offers both high-level integration and affordability, ensuring adaptability and cost-effectiveness.
