Product details
Overview
TPS2057D from Texas Instruments is a triple high-side power-distribution switch with independent 250 mA per channel, 135 mΩ (5 V) on-resistance, active-high enable logic, and integrated thermal/current limiting for USB and hot-plug applications. It operates from 2.7 V to 5.5 V and delivers controlled rise/fall times (2.5 ms typical) to suppress inrush current in peripheral power rails.
For engineers reviewing the TPS2057D datasheet, TPS2057D pinout, TPS2057D application, or TPS2057D equivalent, this device serves as a robust, fault-protected power switch for multi-rail USB hubs, PC peripherals, and embedded systems requiring independent channel control, overcurrent reporting via open-drain OCx outputs, and automatic thermal recovery without system reset.
Technical Context
The TPS2057D integrates three independent N-channel MOSFET 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 current-sense FETs and dual-threshold thermal protection (140°C trip, ~20°C hysteresis) that isolates only the faulted channel.
Its active-high enable inputs (EN1–EN3) interface directly with 3.3 V/5 V logic; overcurrent detection pulls OC1–OC3 low and remains asserted until fault removal. Undervoltage lockout disables switching below ~2 V, and standby supply current is ≤20 µA when all channels are disabled.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channel count | Three independent high-side power switches |
| Continuous current per channel | 250 mA - supports USB bus-powered peripheral loads without external current limiting |
| On-resistance (rDS(on)) | 135 mΩ max at 5 V, 25°C - limits voltage drop to ≤135 mV at 1 A, enabling efficient 5 V rail distribution |
| Enable logic polarity | Active-high - simplifies direct connection to microcontroller GPIO or USB controller enable signals |
| Rise time (tr) | 2.5 ms typical (5.5 V, 1 µF load) - controls inrush surge to prevent host port shutdown during hot insertion |
| Operating input voltage | 2.7 V to 5.5 V - compatible with both 3.3 V and 5 V system rails, including USB 2.0 VBUS |
| Thermal shutdown threshold | ~140°C junction - enables fault containment: only affected channel shuts off, others remain operational |
Pinout & Package
TPS2057D is housed in a 16-pin SOIC (D package), surface-mount, with exposed pad not present. Pin 1 is GND1; pins 8, 9, and 10 are no-connect (NC). Ground planes must accommodate separate GND1 and GND2 connections for optimal noise isolation between input domains.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND1 (Pin 1) | Ground reference for IN1/OUT1/EN1/OC1 | Isolates first channel's return path to reduce crosstalk in multi-load configurations |
| IN1 (Pin 2) | Main input for Channel 1 | Accepts 2.7–5.5 V supply; connects to upstream VBUS or regulated rail |
| EN1 (Pin 3) | Active-high enable for Channel 1 | Drives Channel 1 ON when pulled ≥2 V; TTL/CMOS compatible |
| EN2 (Pin 4) | Active-high enable for Channel 2 | Independent control of second output; allows staggered power-up sequencing |
| GND2 (Pin 5) | Ground reference for IN2/OUT2/EN3/OC2/OC3 | Separate ground domain for second input pair and third channel |
| IN2 (Pin 6) | Main input for Channels 2 & 3 | Shared input for OUT2 and OUT3; supports dual-output configuration from single source |
| EN3 (Pin 7) | Active-high enable for Channel 3 | Enables third output independently; supports three discrete power domains |
| OC1 (Pin 16) | Open-drain overcurrent flag for Channel 1 | Asserts low during overload or thermal fault; requires external pull-up for host interrupt |
| OUT1 (Pin 15) | Switched output for Channel 1 | Delivers controlled 250 mA to downstream load; includes built-in ESD protection (2 kV HBM) |
| OUT2 (Pin 14) | Switched output for Channel 2 | Independent output with same current limit and protection as OUT1 |
| OC2 (Pin 13) | Open-drain overcurrent flag for Channel 2 | Dedicated fault reporting; avoids software polling of shared status lines |
| OC3 (Pin 12) | Open-drain overcurrent flag for Channel 3 | Enables per-channel fault diagnostics in USB hub or multi-peripheral designs |
| OUT3 (Pin 11) | Switched output for Channel 3 | Third independent power rail; shares IN2 but has isolated current sensing and thermal shutdown |
Key Features
| Feature | Design Value |
|---|---|
| Triple independent high-side switches | Enables concurrent, isolated power control for three USB ports or peripheral rails without cross-talk |
| Integrated charge pump | Eliminates need for external boost components; ensures full MOSFET enhancement down to 2.7 V input |
| Dual-threshold thermal protection | 140°C per-channel trip + 160°C global shutdown prevents cascading failure during sustained shorts |
| Per-channel open-drain OCx outputs | Allows hardware-level fault prioritization and interrupt-driven error handling in real-time systems |
| 20 µA max standby current | Supports always-on USB suspend/resume states without compromising system battery life |
| 2-kV HBM ESD rating | Meets IEC 61000-4-2 Level 2 requirements for hot-plug interfaces without external TVS diodes |
Applications
| USB Bus-Powered Hub | Hot-Insertion Peripheral Board |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple high-side power switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS2047D | Active-low enable logic; identical electrical specs and pinout except ENx polarity | Requires inverted control signal; suitable where host MCU drives active-low enables or uses open-collector drivers | Select TPS2047D when existing firmware or logic design already implements active-low enable timing and sequencing. |
| TPD3S014RTER | Single-channel 1.5-A USB switch with integrated data-line ESD protection; no OCx outputs or thermal isolation | Designed for USB 2.0 data+power protection; lacks multi-channel independence and per-rail fault reporting | Choose TPD3S014RTER only for single-port USB Type-A applications needing combined data-line clamping and higher current. |
Compared with TPS2047D and TPD3S014RTER, the TPS2057D uniquely provides active-high enable compatibility across three independent channels with per-channel OCx reporting and thermal fault isolation-critical for scalable, maintainable multi-port USB and embedded power architectures.

FAQ
What is the enable logic polarity of the TPS2057D?
The TPS2057D uses active-high enable inputs (EN1, EN2, EN3): each channel turns ON when its respective enable pin is driven to ≥2 V. This differs from the TPS2047D, which uses active-low enables. The TPS2057D's polarity simplifies direct interfacing with microcontroller GPIOs configured for push-pull high-drive without level-shifting or inversion circuitry.
Does the TPS2057D support independent thermal shutdown per channel?
Yes, the TPS2057D implements dual-threshold thermal protection: a per-channel trip at ~140°C isolates only the overloaded switch, while a global shutdown occurs at ~160°C. This ensures adjacent channels remain operational during localized faults-a key reliability feature confirmed in the SLVS194 datasheet Figure 25 and Section "thermal sense".
What is the maximum continuous current per channel for the TPS2057D?
The TPS2057D is rated for 250 mA continuous output current per channel under recommended operating conditions (2.7 V–5.5 V input, –40°C to 85°C ambient). This value is specified in the "recommended operating conditions" table (Page 5) and validated across temperature and voltage ranges in the electrical characteristics section.
Can the TPS2057D be used in USB 2.0 applications?
Yes, the TPS2057D is explicitly designed for USB applications, including bus-powered hubs and hot-plug peripherals. Its 250 mA per channel limit aligns with USB 2.0 low-/high-power function requirements, and its controlled 2.5 ms rise time prevents VBUS droop that could trigger host port overcurrent protection.
What package type is the TPS2057D supplied in?
The TPS2057D is supplied in a 16-pin SOIC (D package), as confirmed in the "AVAILABLE OPTIONS" table and mechanical drawings on Pages 1 and 2 of the SLVS194 datasheet. It is available taped and reeled (TPS2057DR) and features no exposed thermal pad.
