The NCV303LSN22T1G is a miniature, low-power, highly integrated voltage supervisor device which monitors a single operations voltage. It features an integrated voltage monitor, voltage detector and voltage reset circuits. It is designed to detect power-up or power-down levels of a main power supply or battery voltage, as well as system or module reset control. In addition, it provides a failsafe/backup reset control for low-power systems.

This device features a wide power supply range from 2.5 V to 10 V, a low quiescent current of only 17 μA (typical) at V_DD = 5V, and a wide input voltage range of 4V to 24V. It has an adjustable voltage detector threshold range of 0.6V to V_DD and has a detection accuracy of ±2%. It has an input hysteresis of 10mV and power-on reset capability with a programmable time delay of up to 150 ms.

The NCV303LSN22T1G contains a low-power self-timed reset generator circuit with a programmable reset pulse width from 30μs to 25 msec and adjustable reset threshold from 2.5 V to 10 V. This reset generator automatically asserts a reset signal at the end of the preset period or when the input voltage falls below the preset threshold. It also provides an active-low data hold protection circuit that is enabled by an external reset signal. This allows the reset generator to override an active Supply Good (V_SG) signal under a fail-safe operating condition.

The NCV303LSN22T1G is an ideal solution for applications such as automotive, industrial, computer and consumer electronics that demand low-power operation, improved performance and ultra-small design. It can be used to monitor the power supply voltage of or battery voltage in embedded systems, automotive electronics, motor control systems, and even portable and battery-powered applications.

In automotive applications, the NCV303LSN22T1G can be used to monitor the power supply voltage of the car’s electrical system, detect low voltage conditions, and initiate a safe shutdown or reboot of the system. It can also be used to detect power-up or power-down levels of a voltage source, providing an early warning of potential shutdowns.

In industrial systems, the NCV303LSN22T1G can be used to protect against power supply disruptions, detect overvoltage or undervoltage conditions and initiate a safe shutdown of the system. It can also be used to monitor and detect low-battery voltages, providing a failsafe/backup reset control for low-power systems.

The NCV303LSN22T1G is also ideal for consumer electronics applications, such as smartphones, tablets, laptops, and wearables. It can be used to detect power-up or power-down levels of a battery or main power supply, initiate a reboot or safe shutdown of the device, and ensure that the system can continue to operate properly and reliably.

In summary, the NCV303LSN22T1G is an advanced voltage supervisor device which is ideally suited for low-power and space-constrained applications, including automotive, industrial, computer and consumer electronics applications. It provides an accurate and reliable protection against voltage spikes, surges, and brownouts, ensuring reliable system operation and improved overall performance.
