PMIC - OR Controllers, Ideal Diodes

Category Introduction

Ideal diode controllers, also called O-Ring controllers, are devices designed to control an external pass transistor (usually a FET) in a manner that allows current flow in only one direction, similar to a rectifier diode but with significantly lower conduction loss. Among other applications, they are commonly used for providing reverse-flow protection in power supplies designed to be connected in parallel for sake of redundancy or increased output current capability.

About OR Controllers PMICs & Ideal Diodes PMICs

What are OR Controllers PMICs & Ideal Diodes PMICs?

OR Controllers PMICs

OR Controllers Power Management Integrated Circuits (PMICs) are specialized components designed to manage the distribution and regulation of power within electronic systems. Their primary function is to ensure seamless power supply switching between multiple power sources, such as batteries, adapters, or solar panels, to maintain continuous operation. They operate based on the principle of ORing, where the highest priority power source is selected to supply power, ensuring efficiency and reliability. OR Controllers PMICs are integral in preventing reverse current flow, thereby protecting the system from potential damage.

Ideal Diodes PMICs

Ideal Diodes Power Management Integrated Circuits (PMICs) are specialized semiconductor devices designed to emulate the behavior of an ideal diode. Unlike traditional diodes, which have inherent voltage drops and inefficiencies, ideal diodes PMICs offer near-zero forward voltage drop and minimal reverse leakage current. They achieve this by using advanced control circuitry to dynamically adjust the conduction path, ensuring efficient power flow with minimal energy loss. This makes them particularly valuable in applications where power efficiency and thermal management are critical.
