Product details
Overview
TPS2086D from Texas Instruments is a quad-channel high-side power-distribution switch featuring 80-mΩ N-channel MOSFETs per channel, 500 mA continuous current rating per switch, independent thermal and short-circuit protection with open-drain OC outputs, and CMOS/TTL-compatible enable inputs. It operates from 2.7 V to 5.5 V and is used in hot-plug USB peripheral ports, industrial I/O modules, and embedded system power rail sequencing.
For engineers reviewing the TPS2086D datasheet, TPS2086D pinout, TPS2086D application, or TPS2086D equivalent, this page delivers verified specifications, SOIC-16 package mapping, functional pin roles, real-world use cases for capacitive-load management and fault-isolated power control, and two validated alternative parts with documented differences.
Technical Context
The TPS2086D integrates four independent high-side N-channel MOSFET switches with internal charge-pump gate drivers enabling full operation down to 2.7 V input. Each channel features dedicated enable logic (active-low for TPS2086D), current-limit sensing via sense-FET architecture, and dual-stage thermal protection that isolates faulty channels at ~140°C while allowing healthy channels to remain operational.
Its overcurrent response uses constant-current limiting (typ. 1.0 A short-circuit trip) followed by thermal shutdown if dissipation persists; the OCx outputs (OCA and OCB) provide open-drain fault signaling with 10 mA sink capability. Rise/fall times are controlled at ~2.5 ms (typ.) to suppress EMI and inrush transients during hot-plug events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channel count | 4 independent high-side power switches |
| rDS(on) max | 135 mΩ at 5 V IN, 125°C - enables low-loss 500 mA delivery in SOIC-16 |
| Continuous current | 500 mA per channel - supports USB 2.0 bus-powered peripherals and sensor rails |
| Input voltage range | 2.7 V to 5.5 V - compatible with 3.3 V and 5 V system rails without level-shifting |
| Enable logic | Active-low EN1–EN4 - matches common microcontroller GPIO active-low reset/enable schemes |
| Thermal trip point | ~140°C per channel - enables fault isolation without cascading shutdown |
| Standby supply current | ≤10 μA - minimizes quiescent drain in always-on power management systems |
Pinout & Package
TPS2086D is housed in a 16-pin SOIC (D) package with exposed pad not present; thermal resistance θJA = 111°C/W. Pin functions are validated per TI SLVS202B datasheet Section "TERMINAL FUNCTIONS" for quad variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN1–EN4 | Logic enable inputs | Active-low control lines - each independently gates one power switch |
| IN1–IN4 | Power input terminals | Drain connections of N-channel MOSFETs - accept 2.7–5.5 V supply inputs |
| OUT1–OUT4 | Switched power outputs | Source connections - deliver controlled 500 mA to downstream loads |
| GNDA, GNDB | Separate ground returns | GNDA serves IN1/IN2/OUT1/OUT2; GNDB serves IN3/IN4/OUT3/OUT4 - reduces ground coupling between channel pairs |
| OCA, OCB | Fault indicator outputs | OCA monitors CH1–CH2; OCB monitors CH3–CH4 - open-drain, active-low reporting |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional switch capability | Prevents reverse current flow from OUT to IN - protects upstream supplies during load faults |
| Internal charge pump | Enables full 80-mΩ rDS(on) performance at 2.7 V IN - eliminates external boost components |
| Independent thermal trip | Shuts off only the overloaded channel at ~140°C - maintains power to other subsystems |
| Undervoltage lockout (UVLO) | Disables all switches below ~2 V IN - ensures clean startup and prevents brownout oscillation |
| EMI-optimized switching | 2.5-ms typical rise time - limits di/dt to reduce conducted/radiated noise in dense PCB layouts |
Applications
| USB Hub Power Management | Industrial I/O Module |
|---|---|
Use Scenario: Distributing 5 V power to four downstream USB 2.0 ports with individual overcurrent protection. IC Role / Device Role / Timing Role: Quad high-side switch providing independent enable/control and fault reporting per port. Use Value: Prevents single-port short from disabling entire hub; OCA/OCB signals allow host MCU to identify failed port without polling. |
Use Scenario: Powering isolated sensor/actuator channels in programmable logic controller (PLC) backplane slots. IC Role / Device Role / Timing Role: Fault-tolerant rail switch enabling hot-swap of I/O modules without system reset. Use Value: GNDA/GNDB separation minimizes crosstalk; thermal independence ensures module-level fault containment. |
| Embedded System Rail Sequencing | Hot-Plug Peripheral Card |
Use Scenario: Staged activation of 3.3 V FPGA core, I/O bank, memory, and interface rails in order of dependency. IC Role / Device Role / Timing Role: Four independently enabled power switches coordinating power-up timing via MCU GPIO. Use Value: Controlled 2.5-ms rise time avoids simultaneous inrush; UVLO guarantees safe power-down on supply sag. |
Use Scenario: Inserting a PCIe add-in card into a powered server backplane with no mechanical interlock. IC Role / Device Role / Timing Role: High-side switch placed between backplane VCC and card circuitry for soft-start control. Use Value: Limits inrush to <1 A during plug-in; OCA/OCB alerts system firmware of insertion fault before damage occurs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad high-side power switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS2085D | Active-high enable inputs (EN1–EN4); identical SOIC-16 package and electrical specs | Requires inverted MCU GPIO drive or level-shifting for enable control vs. TPS2086D | Select when system logic naturally provides active-high enable signals and no inversion is desired |
| TPS2068DR | Quad switch in 16-pin SOIC but with 700 mA per channel, higher rDS(on) (150 mΩ), and no dual thermal trip | Lacks per-channel thermal isolation - single fault may disable all outputs under sustained overload | Acceptable for non-fault-critical applications where cost sensitivity outweighs channel independence |
Compared with TPS2085D and TPS2068DR, the TPS2086D uniquely combines active-low enables with per-channel thermal trip and 500 mA capability in SOIC-16 - making it optimal for modular systems requiring deterministic fault containment and direct GPIO compatibility.

FAQ
What is the maximum continuous current per channel for TPS2086D?
The TPS2086D supports 500 mA continuous current per channel under recommended operating conditions (TA ≤ 85°C, VI(IN) = 2.7–5.5 V). This rating is validated across temperature and input voltage ranges per TI SLVS202B datasheet Section "ELECTRICAL CHARACTERISTICS", and derating applies above 85°C ambient per the Dissipation Ratings Table.
Does TPS2086D support bidirectional current flow?
No, the TPS2086D is a unidirectional high-side switch. Its N-channel MOSFET configuration blocks reverse current from OUT to IN, preventing backfeeding into the supply rail. This behavior is inherent to its high-side topology and is confirmed in the "DETAILED DESCRIPTION" section of the datasheet.
How does the thermal protection work on TPS2086D?
The TPS2086D implements dual-stage thermal protection: at ~140°C junction temperature, only the overloaded channel shuts off while others remain active; if temperature exceeds ~160°C, all channels disable. Recovery is automatic after cooling ~20°C, and the OCx outputs assert low during both overcurrent and overtemperature events.
What is the function of GNDA and GNDB pins on TPS2086D?
GNDA is the ground return for channels 1 and 2 (IN1, IN2, OUT1, OUT2); GNDB serves channels 3 and 4 (IN3, IN4, OUT3, OUT4). This split-ground design minimizes shared-impedance coupling between channel pairs, improving noise immunity and fault isolation in multi-rail systems.
Can TPS2086D be used with a 3.3 V supply?
Yes, the TPS2086D operates across 2.7 V to 5.5 V input range. At 3.3 V, its typical rDS(on) is 90–125 mΩ (per datasheet Table "POWER SWITCH"), supporting full 500 mA delivery with ≤200 mV dropout - suitable for 3.3 V logic and peripheral rails without additional regulation.
