Texas Instruments TPS2058D

Overview

TPS2058D from Texas Instruments is a quad-channel, active-high enable, current-limited high-side power-distribution switch featuring 135-mΩ (5-V) N-channel MOSFETs, 250 mA continuous per channel, independent thermal and overcurrent protection with open-drain OCx outputs, and operation from 2.7 V to 5.5 V - used in USB bus-powered hubs and hot-plug peripheral power management.

For engineers reviewing the TPS2058D datasheet, TPS2058D pinout, TPS2058D application, or TPS2058D equivalent, key selection criteria include active-high enable logic, per-channel fault reporting via OCx pins, SOIC-16 package compatibility, and compliance with USB power-switching requirements for bus-powered hubs and portable peripherals.

Technical Context

The TPS2058D integrates four independent high-side N-channel MOSFET switches with internal charge-pump gate drive enabling full operation down to 2.7 V input. Each channel features dedicated current-sense FETs and thermal trip circuitry with dual-threshold shutdown (≈140°C primary, ≈160°C secondary) to isolate faults without affecting adjacent channels.

Its enable inputs accept TTL/CMOS logic levels; OCx outputs are open-drain and active-low under overcurrent or overtemperature conditions. Rise/fall times are controlled (2.5 ms typical rise, 4.4 ms typical fall at 5.5 V) to suppress inrush current and EMI during switching of heavy capacitive loads.

FAQ

What is the enable logic polarity of the TPS2058D?

The TPS2058D uses active-high enable inputs (EN1–EN4). A logic high on any EN pin turns on its corresponding power switch; a logic low disables it. This differs from the TPS2048D, which uses active-low enables. The TPS2058D's polarity simplifies direct interfacing with most microcontroller GPIOs without external inverters or pull-down resistors.

Does the TPS2058D provide per-channel overcurrent reporting?

Yes, the TPS2058D provides dedicated open-drain overcurrent outputs (OC1–OC4), each active-low when its respective channel experiences overcurrent or overtemperature. These outputs require external pull-up resistors and can be monitored individually by a host MCU to identify and isolate faults without affecting other channels - a key capability in multi-port USB hubs.

What is the maximum continuous current per channel for the TPS2058D?

The TPS2058D supports 250 mA continuous current per channel under recommended operating conditions (2.7 V to 5.5 V input, –40°C to +85°C ambient). It also features current limiting at approximately 440 mA (typical at 25°C), entering constant-current mode during overload before thermal shutdown engages if the condition persists.

Can the TPS2058D operate from a 3.3-V supply?

Yes, the TPS2058D operates from 2.7 V to 5.5 V, including 3.3-V systems. At 3.3 V, its typical r_DS(on) is 105 mΩ (25°C), rising to 150 mΩ at 125°C junction temperature. Its internal charge pump ensures reliable gate drive even at minimum input voltage, maintaining full functionality without external boost components.

Is the TPS2058D pin-compatible with other devices in the TPS20xx family?

The TPS2058D shares identical pinout and package (SOIC-16) with the TPS2048D, enabling direct PCB footprint reuse. However, enable polarity differs: TPS2058D is active-high, TPS2048D is active-low. Swapping them requires firmware or hardware logic adjustment - they are not drop-in replacements without design review.
