Power Integrations\' PI2003-00-QEIG is a part of the company\'s Ideal Diode and OR controllers family. It is an electronically controlled switching device, designed to provide an electrically equivalent solution to an ideal diode or OR circuit. The PI2003-00-QEIG is an integrated, current-mode controller with integrated FETs, suitable for input power from 4.0 V to 60 V.

The PI2003-00-QEIG combines the ideal diode and OR features in one IC, with its OR controller operating in both directions, which allows it to control two different loads, connected to either side of its input. Its integrated P-channel and N-channel FETs provide symmetrical control of the two loads, with no external components required. The controller also employs current-mode architecture and a constant-current mode of operation, allowing it to remain stable in a low-impedance environment, such as is typically seen in power distribution and storage applications involving batteries, renewable energy, automotive, and industrial equipment.

The PI2003-00-QEIG integrates a number of features to ease system design, such as programmable current limiting, overcurrent protection, and adjustable overvoltage protection. It also features optional power-good, power-fail, and light load detect outputs, which can be helpful in designing power systems. It is available in both through-hole and surface mount packages, and also features a low-power sleep mode that can significantly improve efficiency.

The PI2003-00-QEIG is suitable for a wide range of applications where solid-state control of current is required, such as power management, voltage regulation, energy storage, lighting, and power conversion. Its low quiescent current draw makes it a good fit for energy efficient applications, while its high voltage and current ratings make it a suitable replacement for bulky, unreliable diode/OR circuits.

The PI2003-00-QEIG is part of Power Integrations\' family of ideal diode and OR controllers, and it can be used to create reliable, efficient, and cost-effective power systems that are easy to design and implement. Its current-mode architecture provides superior performance in demanding applications, while its integrated FETs and comprehensive protection features make it an ideal choice for a wide range of applications where diode/OR control is needed.
