Battery Backup Unit (BBU)

Typically, systems have relied on Uninterruptible Power Supplies to ensure uninterrupted operation, data integrity and system availability by providing immediate ride‑through power during grid disturbances or outages. For today’s high-power AI and data center server architectures, highly integrated and scalable Battery Backup Units (BBUs) play this critical role. Meeting the needs for higher efficiency, fast transient response, compact form factors and reliable operation under continuous high thermal stress.

Design considerations

  • Ideal Diodes vs. Schottky: For higher efficiency and lower heat generation, use Nexperia’s integrated ideal diodes (like the NID5100 or NID1100). These provide the low power loss of MOSFETs with the reverse current blocking of traditional diodes, crucial for seamless power ORing.​
  • Isolation MOSFETs must handle massive energy discharges during fault conditions. Nexperia recommends ASFETs (Application Specific MOSFETs) with strong SOA performance to operate safely until the battery is isolated.​
  • Use load switches with adjustable current limits (110 mA to 2.5 A) and active reverse current blocking to protect the upstream system from damage.​
  • Implement high-robustness ESD protection with low dynamic resistance and low capacitance (such as TrEOS technology) to maintain signal integrity on communication lines.​
  • Use Nexperia's electrothermal MOSFET models during the preliminary design stage to accurately simulate dynamic characteristics and avoid late-stage EMI issues (AN50012). ​
  • For the Battery Management Systems use external MOSFETs for active or passive cell balancing in high current systems and : Integrate Zener diodes in the balancing stage to protect both the FETs and the individual battery cells
