Overview: Product Folder Order Now Technical Documents Tools & Software Support & Community TPS66020, TPS66021 SLVSEW8B – AUGUST 2019 – REVISED DECEMBER 2019 TPS6602x Integrated Source and Sink Power Multiplexer with VBUS LDO.

General Description

The TPS6602x is a full-featured power switch multiplexer that contains an integrated 5-V Source power path and a 4-V to 22-V Sink power path.

The 5-V Source path limits the output current to a safe level by operating in a constant-current mode when the output load exceeds the selected current-limit threshold.

Each power path supports overtemperature and reverse current protection.

Key Features

  • 1 Integrated 30 mΩ (typical), 32-V tolerant NFET 5V source path, up to 3 A.
  • Integrated 22 mΩ (typical), 32-V tolerant NFET 4V to 22-V sink path, up to 5 A.
  • Selectable current limit for 5-V source path.
  • Built-in soft-start to limit in-rush currents.
  • Integrated high voltage VBUS LDO regulator (3.3- V or 5.0-V per device type).
  • Optional VBUS overvoltage protection via pin configuration.
  • System supply and VBUS undervoltage protection.
