The NCP4303BDR2G is a power supply controller, monitor, and supervisor, released by ON Semiconductor. It offers a cost-effective and space-saving solution for the monitoring, controlling, and protection of multi-rail power systems such as those found in automotive or consumer applications. The NCP4303BDR2G is a fully integrated solution for a wide range of power applications and provides a cost-effective and space-saving alternative to discrete power solutions.

In terms of features, the NCP4303BDR2G provides integrated high-side and low-side drivers for controlling linear regulators, a four-channel configurable linear regulator fault manager, power good detection, power on reset and delay, monitoring of voltage and temperature, an external reference, and other features. As a result, the NCP4303BDR2G can help optimize performance, reduce space requirements and the overall cost.

The NCP4303BDR2G is based on a proprietary CMOS fabrication process, and is designed with analog and digital circuits. This provides a wide range of application areas, such as automotive power control, industrial power supplies, communications, consumer electronics, and other applications.

The NCP4303BDR2G is designed to provide system protection that can prevent catastrophic events in the event of a fault. A few examples include protection for voltage overshoot and undershoot, open drain or ground, overcurrent protection, over temperature protection, and protection from reset window violations.

The NCP4303BDR2G also provides tight control and monitoring of up to four linear regulators that may each be powered from a different source. It can monitor voltage, current, and temperature, and provide trip actions such as shutdown, latch off, warning, or pulse trip. To minimize system risk, the NCP4303BDR2G has extensive fault reporting capabilities, which can detect and report voltage, current or temperature faults, as well as power good assertions to indicate that the selected power supply rails are within the specified range.

The NCP4303BDR2G also features a configurable power on reset/delay function, which can be enabled or disabled to control the reset behavior of multiple power rails. This allows system designers to select the optimal settings that maximize system stability and performance.

The NCP4303BDR2G is ideal for applications that require protection and control of power rails, including automotive interior/exterior lighting, navigation systems, safety systems, and automotive audio systems. It is also suitable for power management systems in industrial control and communications systems, and in consumer applications such as wearables and handheld electronics.

The NCP4303BDR2G is the ideal choice for system designers who need to reduce cost, space and the burden of discrete power solutions. With its integrated high-side and low-side drivers and fault protection, it provides system designers with the capability to optimize their designs while minimizing their risk. Additionally, the NCP4303BDR2G offers a wide range of features and performance, making it an ideal choice for applications requiring power control, monitoring, and system protection.
