PMIC (Power Management Integrated Circuit) is any kind of integrated circuit that is used in the power supply of a system. A Super vector is a type of PMIC designed to protect the system from unsafe voltage levels due to process variation, current overload, and environmental conditions. Supervisors are popularly used in automotive, medical, industrial, consumer, and aerospace applications. The NCP303LSN27T1G is a Precision fixed 5V low-voltage supervisor IC produced by ON Semiconductor. It offers precise voltage monitoring and precise reset time delay capabilities. The device is designed with industry-grade accuracy and ensures reliable supply for precise input voltage monitoring. This IC provides precise voltage monitoring for single or multiple power supplies and reset timing for the protection of microprocessor-based systems.
Application fields of the NCP303LSN27T1G
The NCP303LSN27T1G is popularly used in multiple applications such as lighting and automotive, consumer electronics, and industrial. The device can be used as a voltage regulator for low-voltage power applications in consumer electronics. Industrial applications include providing precise voltage monitoring of both single and multiple power supplies in factory automation, machine tooling, and process control systems. In automotive applications, the device can be used to provide precise voltage monitoring of batteries in electric and hybrid vehicles. In satellite and aerospace applications, the precision features of the device can be used to provide reliable protections for mission-critical systems.
Working principle of the NCP303LSN27T1G
The NCP303LSN27T1G is composed of two comparator circuits, with one being the reset circuit and the other being the supply voltage comparator. The first comparator is designed to monitor the reset voltage threshold (V RST ) and the second comparator monitors the other power supplies. The device has two active comparator circuits which are configured to generate an open-drain active-low reset signal, RESET, and a logic output, POR. When the input voltage drops below the defined V RST voltage, the reset signal is generated and is held for about 200ms so that microprocessor setups can properly read the signal. The POR signal is active when an input voltage is above the defined POR voltage.
The device also provides three hysteresis levels to prevent false triggering of the reset signal due to power supply noise or ringing. The hysteresis levels are configurable and provide 3V, 4.3V and 4.5V of hysteresis which can be adjusted depending on the application. The device also features an additional disable circuit that can be used to completely disable the device when required. This is done by asserting the RESET and POR pins to low levels.
In summary, the NCP303LSN27T1G is a precise fixed 5V low-voltage supervisor IC with precise voltage monitoring capabilities. It is popularly used in automotive, industrial, consumer, and aerospace applications to provide reliable supply for precise input voltage monitoring and precise reset time delay capabilities.
