Dual high-side switch with integrated protection
The TPS2062CDR: The internal N-channel MOSFETs present a typical 90 mOhm on-resistance, keeping conduction losses low in USB hubs, set-top boxes, and other 5 V rail distribution tasks. Each channel is independently controlled via an active-high, non-inverting On/Off logic interface. The 1:2 input-to-output ratio means a single enable signal gates both channels simultaneously — useful for ganged port switching where individual control is not needed.
Protection suite and status feedback
Fault protection covers the common failure modes in a powered bus: fixed current limiting, over-temperature shutdown, reverse-current blocking, and under-voltage lockout (UVLO). When a fault triggers, the open-drain Status Flag pulls low — a pull-up resistor to the host controller's logic rail lets the firmware read the fault condition. The Load Discharge feature pulls the output down when the switch is turned off, preventing the output capacitor from holding a residual voltage that could confuse downstream devices on the next power-up cycle.
No exposed pad means no thermal-paste or stencil alignment worries — just standard SOIC reflow or drag-soldering. The SOIC-8 body's thermal resistance is modest; at 1 A per channel the 90 mOhm Rds(on) dissipates about 90 mW per channel, well within the package's capability without airflow.
