機能と利点

  • High current power capability: 20A continuous discharge and 50 A surge (≈200 μs), dependent on battery pack specifications.
  • USB C PD input up to 20V, automatically negotiated via the MAX77958 controller for adapters providing ≥3A or ≥5A PDOs
  • Intelligent power path management with the LTC4421 prioritizing USB C input over battery power during charging for optimal efficiency.
  • 3-cell Li-ion/Li polymer battery support, with recommended configurations using Panasonic NCR18650GA cells
  • Expandable CAN interface with daisy chain headers (P8, P9) for multi module system integration.
  • Configurable output current levels based on PD adapter capabilities (20V/3A or 20V/5A).

製品詳細

The ADRD5161-01Z is a compact, high performance power delivery and battery management module that integrates USB C power delivery (PD) negotiation, 3 cell Li ion/Li polymer battery support, and intelligent power path control. It delivers up to 20A continuous discharge and 50A surge current, while prioritizing USB C input power through its LTC4421 based architecture, ensuring efficient system operation during charging. The module additionally supports daisy chainable CAN connectivity and configurable charging/discharging parameters for compatibility with a wide range of battery packs.

This solution provides designers with a robust, ready to integrate energy subsystem suitable for mobile, portable, and robotic applications that require high power, flexible charging options, and reliable battery behavior. With USB C PD negotiation up to 20V, adaptable current capabilities, and support for recommended cells such as the Panasonic NCR18650GA, the ADRD5161-01Z minimizes design complexity while offering strong scalability and performance for modern embedded systems.

APPLICATIONS

  • Automated Guided Vehicles (AGVs)
  • Autonomous Mobile Robots (AMRs)
  • Portable Industrial Devices: 3 series Li ion/Li poly support and USB C PD (up to 20V) enable efficient charging and stable operation in compact battery powered tools
  • Light Electric Mobility Subsystems: Stable power path control ensures safe, predictable operation in small mobility and auxiliary power systems
