The NCP112DR2G is an advanced and highly reliable system supervisory circuit that is used in a wide range of automotive, appliance, and industrial markets. The device provides reset, power-on reset (POR), power-off reset (POR), supervisor functions and voltage monitoring in order to maintain system integrity across different power disturbances and temperature changes. This device is specially designed to meet the various requirements in a variety of applications, from automotive to industrial.

The NCP112DR2G is designed to provide system resets, power-on reset, power-off reset and monitoring of multiple power levels with a single device. It supports voltage monitoring from 4.5V down to 1.2V. The device has a wide input voltage tolerance from 2.7V to 7V with low quiescent current. It also provides a patented power-on reset with adjustable debounce times. The NCP112DR2G is designed for applications where multiple power domains are used for a range of power domains, such as automotive and industrial.

The NCP112DR2G offers a wide range of features, providing the capability to monitor multiple power domains. It includes two voltage supervisors with active-high, active-low, and dual active-low reset outputs, plus an active reset signal output. It also includes a delay circuit, which provides a reset signal after a selectable delay. The device also contains a Watchdog timer, which can be used to monitor system health and a power-on reset latch. The NCP112DR2G offers a wide temperature range of -40 to +125°C, providing maximum flexibility for automotive and industrial applications.

The working principle of the NCP112DR2G is that when the supply voltage is within the specified range, the reset signal is kept inactive. This is useful when there are power-on reset conditions that need to be detected or in order to guard against malfunctioning or crashing of the system due to inputs or IC malfunctions. The NCP112DR2G can detect both input voltage low and input voltage high conditions, and can provide higher active reset signals in both cases, actively keeping the system from entering an unstable state. The patented power-on reset delay circuitry provides an adjustable active reset signal at the end of a selectable delay time, allowing more configuration options in order to tailor the pulse width to the individual system application.

The NCP112DR2G is a highly reliable and feature rich system supervisory circuit which can be used in a variety of applications, from automotive to industrial. It operates with a wide input voltage range, a wide temperature range, and is capable of monitoring multiple power domains. Its reset and power-on reset features are able to keep the system in a stable state across power disturbances and temperature changes, allowing for its wide range of application fields. With its robust feature set, the NCP112DR2G is an excellent choice for any system requiring voltage supervisory and reset capabilities.
