Texas Instruments TPS2058DR

Overview

TPS2058DR from Texas Instruments is a quad-channel, active-high enable, current-limited high-side power-distribution switch with 135-mΩ on-resistance (at 5 V), 250 mA continuous per channel, thermal and short-circuit protection, and SOIC-16 packaging. It serves as a fault-protected USB port power controller in bus-powered hubs and peripheral hot-plug interfaces.

For engineers reviewing the TPS2058DR datasheet, TPS2058DR pinout, TPS2058DR application, or TPS2058DR equivalent, key selection criteria include active-high enable logic, independent overcurrent flag outputs (OC1–OC4), 2.7–5.5 V input range, 20 µA standby current, and thermal cycling behavior under sustained overload.

Technical Context

The TPS2058DR integrates four independent N-channel MOSFET high-side switches, each driven by an internal charge pump enabling operation down to 2.7 V without external components. Each channel features dedicated current-sense FETs and thermal sense circuitry with dual trip points (140°C primary, 160°C secondary) for isolated fault shutdown.

Its enable inputs are TTL/CMOS-compatible and active-high; overcurrent outputs OC1–OC4 are open-drain, active-low signals tied to individual channels. Undervoltage lockout engages below ~2 V, and rise/fall times are controlled (2.5 ms typical rise, 4.4 ms typical fall at 5.5 V) to limit inrush EMI.

Key Specifications

FAQ

What is the enable logic polarity of the TPS2058DR?

The TPS2058DR uses active-high enable inputs (EN1–EN4). A logic high (≥2 V) turns on the corresponding channel; a logic low disables it and reduces supply current to ≤20 µA. This differs from the TPS2048DR, which uses active-low enables. The TPS2058DR's polarity simplifies direct interfacing with most microcontroller GPIOs without external inverters.

Does the TPS2058DR support dual independent input rails?

Yes, the TPS2058DR supports two independent input domains: IN1/GND1 powers OUT1 and OUT2, while IN2/GND2 powers OUT3 and OUT4. Each domain operates from 2.7–5.5 V, and grounds are physically separated to prevent noise coupling. This enables true dual-rail architectures-for example, 5-V USB peripherals and 3.3-V sensors-within a single IC.

How does thermal protection work on the TPS2058DR?

The TPS2058DR implements channel-isolated thermal protection with a primary trip at ~140°C. When a single channel overheats due to overload, only that switch shuts off-leaving other channels operational. After cooling ~20°C, it auto-recovers. At ~160°C, both switches on the same input domain shut down. The OCx pins assert low during all thermal or overcurrent events, providing unambiguous fault signaling to the host.

Can the TPS2058DR drive a 100-µF capacitive load safely?

Yes-the TPS2058DR's controlled 2.5-ms rise time (at 5.5 V) and current-limiting architecture safely manage inrush into 100-µF loads. Figure 8 in the datasheet confirms stable operation with 100-µF and larger capacitors. For heavy capacitance, adding a 500-µs RC filter to OCx (per Figure 30) prevents false overcurrent triggers caused by transient inrush.

What is the maximum continuous current per channel for the TPS2058DR?

The TPS2058DR delivers 250 mA continuous current per channel across the full –40°C to 85°C ambient temperature range. This rating is validated with 135-mΩ max r_DS(on) at 125°C junction temperature and accounts for thermal derating in SOIC-16 packaging (725 mW at 25°C, derated 5.8 mW/°C above).
