PMIC - OR Controllers, Ideal Diodes
PMIC - OR Controllers, Ideal Diodes | Integrated Circuits (ICs)
Definition:
PMIC (Power Management Integrated Circuit) - OR Controllers and Ideal Diodes are specialized components designed to manage power distribution, redundancy, and efficiency in electronic systems. OR Controllers facilitate seamless power source switching between multiple inputs (e.g., primary and backup supplies), while Ideal Diodes emulate the behavior of traditional diodes with near-zero voltage drop, minimizing power loss and heat generation. These ICs are critical in applications requiring uninterrupted power delivery and optimized energy efficiency.
Product Types:
1. OR Controllers: Automatically select the highest available voltage from multiple inputs, ensuring continuous operation in failover scenarios. Common in servers, telecom, and automotive systems.
2. Ideal Diode Controllers: Replace physical diodes with MOSFET-based solutions, reducing forward voltage loss (e.g., from 0.7V to ~20mV). Ideal for battery-powered devices, solar panels, and hot-swap circuits.
3. Integrated ORing + Ideal Diode Solutions: Combine both functionalities for compact designs, such as in PoE (Power over Ethernet) systems or industrial backup modules.
Purchasing Recommendations:
- Voltage/Current Ratings: Match the IC s input/output specs (e.g., 12V/5A) to your system s requirements.
- Protection Features: Prioritize devices with built-in overvoltage (OVP), reverse-current (RCP), and thermal shutdown protection.
- Package & Integration: Opt for space-saving packages (e.g., DFN, QFN) for high-density PCBs, or modules with minimal external components.
- Industry Compliance: Verify certifications like AEC-Q100 for automotive or ISO 7637 for surge tolerance.
