Product details
Overview
TPS2058AD from Texas Instruments is a quad-channel, high-side N-channel MOSFET power-distribution switch with independent enable control per channel, 80-mΩ typical rDS(on) at 5 V, 250 mA continuous current per channel, and integrated overcurrent/thermal protection. It serves as a fault-protected power rail manager in USB peripheral hubs, portable docking stations, and multi-rail embedded systems.
For engineers reviewing the TPS2058AD datasheet, TPS2058AD pinout, TPS2058AD application, or TPS2058AD equivalent, this page delivers verified electrical parameters, D-package terminal mapping, real-world use scenarios for USB-powered peripherals, and validated alternative parts with documented functional differences.
Technical Context
The TPS2058AD integrates four independent high-side switches, each driven by an internal charge pump enabling operation down to 2.7 V input while maintaining gate overdrive. Each channel features dedicated ENx (active-high) inputs, open-drain OCx fault indicators, and dual-threshold thermal shutdown that isolates only the affected channel.
Current limiting is implemented via sense-FET architecture-not external resistors-ensuring minimal voltage drop and accurate trip thresholds of 0.5 A typical under short-circuit conditions. Undervoltage lockout disables all switches below ~2 V, and rise/fall times are controlled to 2.5–4.4 ms to suppress inrush-induced EMI.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Number of channels | 4 independent high-side power switches with separate EN and OC signals |
| rDS(on) (typ, 5 V) | 80 mΩ - enables ≤125 mV dropout at 250 mA, minimizing thermal load |
| Continuous current per channel | 250 mA - supports USB-compliant downstream ports and low-power peripherals |
| Input voltage range | 2.7 V to 5.5 V - compatible with single-cell Li-ion, 3.3 V, and 5 V system rails |
| Enable logic polarity | Active-high (EN1–EN4) - direct interface with 3.3 V/5 V GPIO without level shifting |
| Standby supply current | 20 µA max - ensures ultra-low quiescent draw when all channels disabled |
| Thermal shutdown threshold | ~140°C junction - self-resetting hysteresis (~20°C) prevents latch-up during transient overloads |

Equivalent & Alternatives
The following parts are listed as comparable options for similar power-distribution switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS2048AD | Quad-channel, active-low enable (ENx), same D-16 package and pinout except EN polarity and NC pins | Requires inverted logic drive; not suitable where MCU GPIOs are limited to active-high outputs | Select TPS2048AD only if existing firmware or level-shifter infrastructure supports active-low enables |
| TPS2056AD | Dual-channel version (2× IN/OUT), identical EN polarity, rDS(on), and protection features; uses D-8 package | Half the channel count; requires two devices to match TPS2058AD's quad functionality | Choose TPS2056AD for cost-sensitive dual-rail designs or when board area allows two smaller packages |
Compared with TPS2058AD, TPS2048AD demands logic inversion for enable control but offers identical protection and performance, while TPS2056AD reduces channel density and increases PCB footprint-making TPS2058AD optimal for space-constrained quad-rail systems requiring native active-high control.

FAQ
What is the maximum continuous current per channel for the TPS2058AD?
The TPS2058AD supports 250 mA continuous current per channel across its full operating temperature range (0°C to 85°C ambient). This rating is maintained with proper PCB copper pour and airflow; exceeding it triggers current-limit mode at ~0.5 A short-circuit threshold, followed by thermal shutdown if sustained.
Does the TPS2058AD support bidirectional current flow?
No, the TPS2058AD is a unidirectional high-side switch. Its N-channel MOSFET architecture blocks reverse current flow from OUT to IN. The datasheet explicitly states it "prevents current flow from OUT to IN and IN to OUT when disabled," confirming strict forward-only conduction.
How does the TPS2058AD handle simultaneous overcurrent events on multiple channels?
The TPS2058AD implements independent per-channel current sensing and dual-threshold thermal protection. If multiple channels overload, each OCx output asserts low independently, and only the affected channel shuts down thermally-leaving other channels fully operational until the respective faults clear.
What is the purpose of separate GNDA and GNDB pins on the TPS2058AD?
GNDA and GNDB provide isolated ground returns for the two independent input domains (IN1 and IN2). This separation prevents ground-loop coupling between loads powered from different inputs-critical for noise-sensitive applications like mixed-signal docks or medical interfaces where analog and digital subsystems share a board.
Can the TPS2058AD operate from a 3.3 V supply?
Yes, the TPS2058AD operates from 2.7 V to 5.5 V. At 3.3 V input, its typical rDS(on) is 90–125 mΩ (depending on junction temperature), yielding ≤31 mV dropout at 250 mA-well within most 3.3 V system tolerances. The internal charge pump ensures reliable gate drive even at minimum VIN.
