Product details
Overview
TPS2062DGN from Texas Instruments is a dual-channel, current-limited, high-side power-distribution switch featuring two 70 mΩ N-channel MOSFETs, 1 A continuous output per channel, thermal and short-circuit protection, and operation from 2.7 V to 5.5 V. It serves as a fault-protected load switch in USB-powered peripherals and industrial I/O modules.
For engineers reviewing the TPS2062DGN datasheet, TPS2062DGN pinout, TPS2062DGN application, or TPS2062DGN equivalent, key selection criteria include per-channel current limit accuracy (1.1–1.9 A), undervoltage lockout threshold (2.0–2.6 V), OCx deglitch timing (4–15 ms), and HVSSOP-8 thermal performance (RθJA = 53.6 °C/W).
Technical Context
The TPS2062DGN integrates two independent high-side switches, each with dedicated enable (EN1/EN2) and overcurrent reporting (OC1/OC2) pins. Its internal charge pump enables full gate drive down to 2.7 V input, eliminating external bias components while maintaining controlled 0.6 ms typical rise time and <0.5 ms fall time.
Each channel implements flat current limiting via sense-FET architecture-no external resistor required-and enters constant-current mode at IOS (1.1–1.9 A) during overload. Thermal shutdown activates at 135 °C with 10 °C hysteresis, and recovery occurs automatically after junction cooling to 125 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Continuous Output Current | 1 A per channel - supports stable load switching without derating under 85°C ambient |
| On-Resistance (rDS(on)) | 70 mΩ typical at 5 V - minimizes conduction loss (≤70 mW at 1 A) and self-heating |
| Input Voltage Range | 2.7 V to 5.5 V - compatible with 3.3 V and 5 V logic-supply domains and USB VBUS |
| Current Limit Threshold | 1.1 A min / 1.9 A max - ensures robust short-circuit response across temperature and process variation |
| Rise Time (tr) | 0.6 ms typical - limits inrush current into heavy capacitive loads (e.g., 100 µF bus capacitance) |
| Standby Supply Current | 1 µA max - enables ultra-low-power disable state for battery-backed systems |
| Thermal Shutdown Threshold | 135 °C - protects silicon integrity during sustained overload or poor PCB heatsinking |
Pinout & Package
HVSSOP-8 (DGN) package with exposed PowerPAD™ thermally connected to GND; 0.65 mm pitch, 3.0 mm × 3.0 mm footprint, 1.0 mm height. PowerPAD™ must be soldered to PCB ground plane for thermal compliance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - GND | Ground reference | Primary return path for power, logic, and thermal dissipation via PowerPAD™ |
| 2 - IN | Power input | Common input rail for both channels; must be decoupled locally (≥10 µF ceramic) |
| 3 - EN1 | Channel 1 enable | Active-low logic input; drives CH1 switch ON when pulled low (0 V) |
| 4 - EN2 | Channel 2 enable | Active-low logic input; drives CH2 switch ON when pulled low (0 V) |
| 5 - OC2 | Channel 2 overcurrent flag | Open-drain, active-low output; sinks ≥5 mA when CH2 exceeds current limit |
| 6 - OUT2 | Channel 2 output | Switched high-side output; connects to load when EN2 = low and no fault present |
| 7 - OUT1 | Channel 1 output | Switched high-side output; connects to load when EN1 = low and no fault present |
| 8 - OC1 | Channel 1 overcurrent flag | Open-drain, active-low output; sinks ≥5 mA when CH1 exceeds current limit |
Key Features
| Feature | Design Value |
|---|---|
| Built-in soft-start | Controlled 0.6 ms rise time prevents system-level voltage droop during hot-plug events |
| Deglitched OC reporting | 4–15 ms OC assertion/deassertion window eliminates false trips from transient load spikes |
| No OC glitch at power-up | Internal sequencing ensures OC outputs remain high-Z until valid input voltage and stabilization |
| Undervoltage lockout (UVLO) | 2.0–2.6 V turn-on threshold with 75 mV hysteresis prevents erratic switching near supply brownout |
| Bidirectional switch capability | Prevents reverse current flow from OUT to IN - critical for back-powering prevention in multi-rail systems |
Applications
| USB Peripheral Power Switching | Industrial Digital I/O Module |
|---|---|
Use Scenario: Hot-plugging USB devices (e.g., printers, storage) into embedded host controllers. IC Role / Device Role / Timing Role: Dual-channel high-side switch enabling/disabling VBUS to downstream ports with independent fault reporting. Use Value: Prevents bus collapse during plug-in surge; OC1/OC2 flags allow firmware to isolate faulty ports without system reset. |
Use Scenario: Controlling 24 V DC solenoid valves or LED banks from microcontroller GPIOs. IC Role / Device Role / Timing Role: Fault-protected load driver translating 3.3 V logic signals into isolated 5 V–24 V switched outputs. Use Value: 1 A per channel handles typical solenoid hold currents; thermal shutdown avoids latch-up during coil stall conditions. |

IC Role / Device Role / Timing Role: Independent enable-controlled power rails with synchronized soft-start to meet sequencing timing windows. Use Value: 0.6 ms rise time ensures controlled ramp rate; EN1/EN2 allow precise inter-rail delay via MCU timing. |
Use Scenario: Charging large bulk capacitors (≥100 µF) in PoE-powered access points or surveillance cameras. IC Role / Device Role / Timing Role: Inrush current limiter preventing fuse blow or upstream regulator foldback during cold start. Use Value: Flat current limit holds peak inrush ≤1.9 A regardless of capacitor ESR or input voltage sag. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel power-switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS2062DR | SOIC-8 package; RθJA = 119.3 °C/W vs. DGN's 53.6 °C/W; same electrical specs | Lower thermal performance requires larger copper area or forced air for 1 A continuous operation | Choose TPS2062DR only if SOIC-8 footprint is mandatory and board-level thermal design accommodates higher junction rise. |
| TPS2066DGN | Active-high enable logic (EN1/EN2 high = ON); identical pinout, package, and protection features | Requires inverted control signal routing or level-shifting in existing active-low enable architectures | Choose TPS2066DGN when system logic naturally sources enable signals (e.g., microcontroller GPIOs with pull-up defaults). |
Compared with TPS2062DGN, TPS2062DR trades thermal efficiency for legacy SOIC compatibility, while TPS2066DGN maintains identical form-factor and protection but inverts enable polarity-neither is pin-compatible without layout or firmware changes.

FAQ
What is the maximum continuous current per channel for the TPS2062DGN?
The TPS2062DGN supports 1 A continuous output current per channel across the full operating temperature range (–40°C to 85°C ambient). This rating assumes proper PCB thermal design using the PowerPAD™ connected to a minimum 100 mm² copper pour on the top layer and internal ground planes.
Does the TPS2062DGN require external components for gate drive or current sensing?
No. The TPS2062DGN integrates an internal charge pump for gate drive and a sense-FET for current monitoring. No external capacitors, resistors, or diodes are needed for basic operation-only local input/output decoupling capacitors (e.g., 10 µF ceramic at IN, 1 µF at each OUT) are recommended.
How does the TPS2062DGN handle short-circuit faults?
Upon detecting an overload exceeding 1.1–1.9 A, the TPS2062DGN enters constant-current mode, clamping output current while reducing output voltage. If the fault persists and junction temperature reaches 135 °C, thermal shutdown disables both channels. Recovery is automatic once the die cools below 125 °C.
Can the TPS2062DGN be used with 3.3 V logic control signals?
Yes. The EN1 and EN2 inputs accept TTL- and CMOS-compatible logic levels: VIH ≥ 2.0 V and VIL ≤ 0.8 V across 2.7–5.5 V supply. A 3.3 V microcontroller GPIO can directly drive EN1/EN2 low to enable its respective channel without level shifting.
What is the purpose of the OC1 and OC2 pins on the TPS2062DGN?
OC1 and OC2 are open-drain, active-low overcurrent indicators-one per channel. When current exceeds the limit, the corresponding OC pin pulls low (≤0.4 V at 5 mA sink) and remains asserted for ≥4 ms to avoid noise-induced glitches. They interface directly with MCU interrupt inputs or status LEDs.
