Manufacturer: Texas Instruments

Overview: Product Folder Order Now Technical Documents Tools & Software Support & Community TPS66120, TPS66121 SLVSEW9B – AUGUST 2019 – REVISED DECEMBER 2019 TPS6612x Integrated Sink with VBUS LDO Regulator.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The TPS6612x contains an integrated 4-V to 22-V Sink power path.

The power path supports overtemperature and reverse current protection.

VBUS has overvoltage protection with its level being set by an optional external resistor divider.

Key Features

  • 1 Integrated 22 mΩ (typical), 32-V tolerant NFET 4V to 22-V sink path, up to 5 A.
  • 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.
  • Overtemperature protection.
  • Reverse-current protection.
  • Fault pin with de-glitched fault reporting.
  • Sma.
