Protection set that covers real-world fault scenarios
This part packs a full protection suite: fixed current limiting, over-temperature shutdown, reverse-current blocking, and undervoltage lockout (UVLO). The fixed current limit means you don't need to set a resistor — it's baked in, which simplifies the BOM but also means you can't adjust the trip point. The status flag output (open-drain, active low) signals overcurrent or overtemperature events, so a host controller can log the fault or retry the port. Reverse-current protection prevents back-feeding the upstream rail when Vbus is held high by a powered device — a common failure in dual-power scenarios.
Package and temperature range for industrial use
Housed in an 8-HVSSOP package (3.00mm width, exposed pad for thermal dissipation), the TPS2068CDGNR is rated for operation from -40°C to 125°C junction temperature. That covers most industrial and automotive cabin environments. The exposed pad needs a good thermal via pattern to the ground plane if you plan to run near 1.5A continuously — the datasheet layout recommendation is worth following.
It is ROHS3 compliant (no exemptions), which keeps it clean for EU and global markets.
