Product details
Overview
TPS2814DR from Texas Instruments is a dual 2-input AND gate MOSFET driver with one inverting input per channel, designed for high-speed gate driving of n-channel and p-channel power MOSFETs. It delivers 2-A peak source/sink current, achieves ≤25-ns rise/fall times (VCC = 14 V, CL = 1 nF), operates across 4–14-V supply range, and supports −40°C to 125°C ambient operation - used in synchronous buck converters, motor gate drivers, and DC-DC power stages.
For engineers reviewing the TPS2814DR datasheet, TPS2814DR pinout, TPS2814DR application, or TPS2814DR equivalent, key selection criteria include confirmed AND logic function with single inversion per driver, SOIC-8 package compatibility, propagation delay ≤40 ns, low 5-µA quiescent supply current, and absence of internal regulator (distinguishing it from TPS2811/12/13).
Technical Context
The TPS2814DR implements two independent AND gates, each with one noninverting and one inverting input (1IN1•1IN2 and 2IN1•2IN2), enabling precise enable/inhibit control of high-side and low-side MOSFETs. Its CMOS input stage features Schmitt-trigger thresholds (~⅓VCC and ~⅔VCC) and <10-pF input capacitance, ensuring noise immunity and fast edge response.
Output stage uses a bipolar-MOSFET parallel architecture to achieve rail-to-rail swing (0.18 V low-level / 9.9 V high-level at 10 V VCC) and robust 2-A peak drive into capacitive loads. No internal regulator is present - REG_IN and REG_OUT pins are unused and must be left unconnected.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Rise/Fall Time | ≤25 ns / ≤25 ns (VCC = 14 V, CL = 1 nF): enables >20-MHz switching in hard-switched topologies |
| Propagation Delay | ≤40 ns max (high-to-low & low-to-high): supports tight timing margins in synchronous rectification |
| Peak Output Current | 2 A source/sink (VCC = 10.5 V): sufficient to drive Hex-3 MOSFETs (e.g., IRF530) in <20 ns |
| Supply Voltage Range | 4 V to 14 V: compatible with 5-V and 12-V control rails; no regulator - excludes 14–40 V operation |
| Quiescent Supply Current | 5 µA max (inputs high or low): minimizes standby power in battery-backed or energy-sensitive systems |
| Operating Temperature | −40°C to 125°C ambient: qualified for industrial and automotive under-hood power stages |
| Input Threshold Hysteresis | ~1.2 V (VCC = 5 V): provides noise margin against ground bounce and EMI in noisy power environments |
Pinout & Package
TPS2814DR is supplied in an 8-pin SOIC (D) package with tape-and-reel (R suffix) packaging. Pin 1 is 1IN1 (noninverting input of Driver 1); Pin 2 is 1IN2 (inverting input of Driver 1); Pin 3 is 2IN1 (noninverting input of Driver 2); Pin 4 is 2IN2 (inverting input of Driver 2); Pin 5 is 2OUT (output of Driver 2); Pin 6 is VCC; Pin 7 is 1OUT (output of Driver 1); Pin 8 is GND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1IN1 | Noninverting input, Driver 1 | Enables gate drive when asserted high; paired with 1IN2 for AND logic |
| 1IN2 | Inverting input, Driver 1 | Active-low enable: drives 1OUT only when 1IN1 = HIGH AND 1IN2 = LOW |
| 2IN1 | Noninverting input, Driver 2 | Independent enable path for second MOSFET; supports complementary or phase-shifted control |
| 2IN2 | Inverting input, Driver 2 | Provides active-low control for 2OUT; allows dead-time insertion without external logic |
| 1OUT / 2OUT | Push-pull gate drive outputs | Rail-to-rail swing (0.18 V / 9.9 V @ 10 V) ensures full enhancement/depletion of logic-level MOSFETs |
| VCC | Driver supply input | Must be decoupled with 0.1-µF ceramic capacitor; powers both drivers and input logic |
| GND | Power and signal reference | Low-inductance connection required between driver GND and MOSFET source to minimize shoot-through |
Key Features
| Feature | Design Value |
|---|---|
| Dual 2-input AND logic with per-driver inversion | Enables independent, synchronized control of high-side/low-side switches with built-in dead-time capability |
| Bipolar-MOSFET parallel output stage | Guarantees strong turn-on (2 A) and turn-off (2 A) drive while reaching within 0.2 V of VCC and GND rails |
| 25-ns max rise/fall time (1 nF load) | Reduces MOSFET switching losses in high-frequency DC-DC converters (>500 kHz) |
| 5-µA max supply current | Lowers system standby power - critical for always-on industrial controllers and IoT edge nodes |
| −40°C to 125°C operation | Validated for under-hood automotive DC-DC modules and industrial motor drives without derating |
Applications
| Synchronous Buck Converter | Motor Gate Driver |
|---|---|
Use Scenario: Driving high-side and low-side N-channel MOSFETs in a 12-V input, 3.3-V/3-A output buck regulator with 500-kHz switching frequency. IC Role / Device Role / Timing Role: Dual AND gate driver providing phase-aligned, dead-time-controlled gate signals to minimize shoot-through during transitions. Use Value: 25-ns rise time and 40-ns propagation delay ensure precise timing alignment, reducing conduction loss and improving efficiency by ≥1.2% vs. slower drivers. |
Use Scenario: Controlling H-bridge MOSFETs in a 24-V brushed DC motor driver for industrial automation, requiring bidirectional rotation and braking. IC Role / Device Role / Timing Role: Independent AND logic per channel enables simultaneous forward/reverse enable with hardware-based interlock to prevent cross-conduction. Use Value: Inverting inputs allow direct connection to microcontroller PWM and direction signals - eliminating external inverters and saving PCB area. |
| Isolated Flyback Controller Interface | High-Voltage Power Supply Sequencing |
Use Scenario: Interfacing isolated gate drive signals from a flyback controller IC to primary-side MOSFETs in a 48-V telecom power supply. IC Role / Device Role / Timing Role: Level-shifting and amplifying low-current logic edges into robust 2-A gate pulses with minimal propagation skew (<5 ns between channels). Use Value: Low 10-pF input capacitance prevents loading of optocoupler or transformer-isolated outputs, preserving signal integrity. |
Use Scenario: Enabling sequential turn-on of multiple power domains (e.g., 12-V bias, 5-V logic, 3.3-V core) in a programmable power supply with fault interlocks. IC Role / Device Role / Timing Role: Using AND logic to require both global ENABLE and domain-specific READY signals before asserting gate drive. Use Value: Built-in Schmitt-trigger inputs reject noise on long enable traces, preventing false triggering during hot-swap or brown-out events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual MOSFET driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS2814D | Same die, PDIP-8 package (no R suffix); identical electrical specs and pinout | Through-hole assembly only; not suitable for automated SMT lines | Select TPS2814D only for prototyping or legacy through-hole designs where reflow compatibility is unnecessary |
| UCC27524ADRV | Single-supply 5-V–16-V, dual 5-A sink/source, no logic gates; inverting/noninverting inputs per channel | Requires external AND logic for enable control; higher drive strength but larger footprint (WSON-8) | Choose UCC27524ADRV when >2-A peak current or tighter layout constraints demand WSON packaging and higher drive headroom |
Compared with TPS2814DR, TPS2814D offers identical performance in through-hole form but lacks tape-and-reel support for SMT production, while UCC27524ADRV trades integrated logic for higher current and smaller package - making TPS2814DR optimal for cost-sensitive, logic-integrated 12-V gate drive applications.

FAQ
Does the TPS2814DR include an internal voltage regulator?
No, the TPS2814DR does not include an internal regulator. Unlike TPS2811/12/13, it lacks REG_IN and REG_OUT functionality. Pins 1–4 and 5–8 are dedicated to logic inputs and outputs only. The TPS2814DR requires a clean, regulated 4–14-V supply applied directly to VCC (Pin 6), and REG_IN/REG_OUT pins must remain unconnected.
What logic function does the TPS2814DR implement per channel?
The TPS2814DR implements a dual 2-input AND gate, with one inverting input per driver: Driver 1 output (1OUT) = 1IN1 • NOT(1IN2); Driver 2 output (2OUT) = 2IN1 • NOT(2IN2). This configuration enables hardware-enforced dead-time insertion and independent enable/disable control without external logic gates.
Can the TPS2814DR drive both high-side and low-side N-channel MOSFETs in a half-bridge?
Yes, the TPS2814DR can drive both high-side and low-side N-channel MOSFETs in a half-bridge configuration. Its rail-to-rail output swing (0.18 V low / 9.9 V high at 10 V VCC), 2-A peak current, and matched propagation delays (<5 ns skew) ensure reliable switching. However, high-side drive requires bootstrap or isolated supply - the TPS2814DR itself does not generate floating bias.
What is the maximum capacitive load the TPS2814DR can drive while maintaining 25-ns rise time?
The 25-ns max rise time specification for the TPS2814DR is guaranteed with a 1-nF capacitive load and VCC = 14 V. At higher loads (e.g., 10 nF), rise time degrades to ~60 ns. For loads >2 nF, paralleling both drivers (1OUT + 2OUT) reduces effective rise time by ~30%, extending usable range to ~3 nF while maintaining sub-35-ns performance.
Is the TPS2814DR pin-compatible with other TPS28xx family members like TPS2812DR?
No, the TPS2814DR is not pin-compatible with TPS2812DR or other TPS2811/12/13 variants. TPS2814DR uses a 4-input logic layout (1IN1, 1IN2, 2IN1, 2IN2 on Pins 1–4), whereas TPS2812DR has dual noninverting inputs (1IN, 2IN on Pins 2 and 4) and includes REG_IN/REG_OUT on Pins 1 and 8. Physical pin assignments differ fundamentally across logic variants.
