Product details
Overview
TPS2063D from Texas Instruments is a triple-channel, current-limited, high-side power-distribution switch featuring three independent 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 input. It serves as a robust load-switching solution in USB-powered peripherals, industrial I/O modules, and embedded systems with multiple downstream rails.
For engineers reviewing the TPS2063D datasheet, TPS2063D pinout, TPS2063D application, or TPS2063D equivalent, key selection criteria include per-channel enable control (EN1/EN2/EN3), accurate overcurrent trip threshold (1.6–3.0 A), deglitched OCx fault reporting, undervoltage lockout (2.0–2.5 V), and SOIC-16 package compatibility with thermal management via PowerPAD™.
Technical Context
The TPS2063D integrates three independent high-side switches, each driven by an internal charge pump enabling full gate drive down to 2.7 V input-eliminating external components while controlling rise/fall times (0.4–0.6 ms typical) to suppress inrush surges. Each channel features dedicated current-sense FETs for real-time overload detection without series resistance penalty.
Its dual-input architecture supports two independent input rails (IN1 for OUT1/OUT2; IN2 for OUT3), enabling flexible rail partitioning. Overcurrent response includes peaking-limit behavior: fast trip at IOC (1.6–3.0 A) followed by constant-current hold at IOS (1.1–2.1 A), with automatic thermal shutdown recovery at 125 °C after junction cooling.
Key Specifications

IC Role / Device Role / Timing Role: High-side switching with UL listing and thermal shutdown provides certified overcurrent protection per IEC 60601-1 Clause 8.7. Use Value: Meets medical safety standards without external crowbar circuits; OCx flags feed directly to system watchdog for fail-safe shutdown. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side power-switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS2067DR | Same 3-channel architecture, but uses active-high EN inputs (EN1/EN2/EN3 logic high = ON) | Requires inverted enable logic in host MCU firmware or level-shifting circuitry | Select when system control logic is natively active-high and board layout permits SOIC-16 footprint reuse |
| TPS2053D | Legacy pin-compatible variant with identical SOIC-16 package and pinout, but higher rDS(on) (100 mΩ typ) and no UVLO | Lacks undervoltage lockout and has reduced current capability (0.75 A continuous) | Acceptable for cost-sensitive, non-UVLO applications where thermal margin allows higher conduction loss |
Compared with TPS2063D, TPS2067DR offers identical protection and performance with reversed enable polarity-ideal for new designs using active-high GPIOs-while TPS2053D trades off efficiency and safety features for legacy compatibility and lower unit cost in less demanding environments.

FAQ
What is the maximum continuous current per channel for the TPS2063D?
The TPS2063D supports 1 A continuous output current per channel under recommended operating conditions (VI(IN) = 2.7 V to 5.5 V, TJ ≤ 125 °C). This rating is sustained with proper PCB thermal design-especially via the PowerPAD™-and derates linearly above 85 °C ambient per the RθJA of 53.6 °C/W in SOIC-16 package.
Does the TPS2063D support bidirectional current flow?
No-the TPS2063D is a unidirectional high-side switch. Its N-channel MOSFET architecture blocks reverse current from OUT to IN when disabled. While it does not conduct backwards, its design prevents back-powering of upstream supplies, making it suitable for isolation between independently regulated rails.
How does the overcurrent protection work in the TPS2063D?
The TPS2063D implements peaking-type current limiting: it trips at IOC (1.6–3.0 A) then holds output current at IOS (1.1–2.1 A) in constant-current mode. If overload persists, thermal shutdown activates at 135 °C. OC1–OC3 pins assert low after 4–15 ms deglitch delay, allowing microcontroller polling without spurious interrupts.
Can the TPS2063D operate from a 3.3 V supply?
Yes-the TPS2063D operates from 2.7 V to 5.5 V, including standard 3.3 V systems. At 3.3 V input, rDS(on) increases to ~90 mΩ (typ), resulting in ~90 mW conduction loss at 1 A. The internal charge pump remains functional, ensuring full gate drive and reliable switching performance without external boost circuitry.
What is the purpose of the NC pins (8, 9, 10) on the TPS2063D?
Pins 8, 9, and 10 on the TPS2063D are No-Connect terminals-unbonded and electrically isolated inside the SOIC-16 package. They must remain unconnected in layout. TI recommends leaving them floating or optionally grounding them to improve mechanical stability; neither choice affects electrical performance or thermal behavior.
