Texas Instruments TPS2813D

Overview

TPS2813D from Texas Instruments is a dual complementary MOSFET driver IC with one inverting and one noninverting channel, 2-A peak output current at 14 V, 25-ns max rise/fall times (1-nF load), and integrated 10–13-V regulator supporting 14–40-V input range. It operates across −40°C to 125°C and targets high-frequency synchronous buck converters and half-bridge gate driving.

For engineers reviewing the TPS2813D datasheet, TPS2813D pinout, TPS2813D application, or TPS2813D equivalent, key selection considerations include its complementary logic configuration, regulator-enabled wide-input operation, shoot-through-minimized dual-output architecture, and SOIC-8 package compatibility with industrial motor control and DC/DC power stages.

Technical Context

The TPS2813D integrates two independent gate drivers-one inverting and one noninverting-enabling direct complementary drive of high-side and low-side N-channel MOSFETs without external logic inversion. Its internal linear regulator accepts 14–40 V on REG_IN and delivers a stable 10–13 V to VCC, decoupling driver supply from variable input rails.

Each output stage combines bipolar and MOSFET transistors in parallel to achieve rail-to-rail swing (0 V to VCC) with 2-A peak sourcing/sinking capability, ensuring robust turn-on/turn-off of low-threshold MOSFETs. Input thresholds follow CMOS Schmitt-trigger behavior (≈1/3 VCC low-to-high, ≈2/3 VCC high-to-low), delivering noise immunity and consistent timing independent of input slew rate.

FAQ

What is the function of the REG_IN and REG_OUT pins on the TPS2813D?

The REG_IN pin accepts 14–40 V unregulated input and feeds the internal linear regulator. The REG_OUT pin delivers a regulated 10–13 V output, which powers the VCC rail and may supply up to 20 mA to external circuitry. When unused, both pins can be left floating or tied together to VCC or GND per TI design guidelines.

Can the TPS2813D drive both high-side and low-side N-channel MOSFETs in a half-bridge without external components?

Yes - the TPS2813D's complementary logic (one inverting and one noninverting output) enables direct drive of low-side and high-side N-MOSFETs. However, high-side drive requires either a bootstrap capacitor network or isolated supply; the TPS2813D itself does not generate floating voltage but provides matched timing and 2-A current to both gates.

What is the maximum capacitive load the TPS2813D can drive while maintaining 25-ns rise time?

The 25-ns max rise time is specified at CL = 1 nF with VCC = 14 V. At higher loads (e.g., 10 nF), rise time degrades to ~60 ns. For optimal performance, keep total gate + layout capacitance ≤1.5 nF; paralleling both outputs reduces effective rise time by ~30% for loads up to 2 nF.

Does the TPS2813D include protection features such as overcurrent or thermal shutdown?

No - the TPS2813D has no internal overcurrent, overtemperature, or undervoltage lockout protection. It relies on external circuit design (e.g., gate resistors, current-sense feedback, thermal interface) for fault management. Its robust 2-A output stage and low shoot-through current inherently improve reliability but do not constitute active protection.

How does the input hysteresis of the TPS2813D improve system robustness?

The TPS2813D features CMOS Schmitt-trigger inputs with ≈7.3-V hysteresis at VCC = 14 V (1 V low threshold, 8.3 V high threshold). This prevents oscillation or chatter during slow or noisy input transitions - critical in industrial environments with long PCB traces, relay bounce, or EMI-coupled control signals.
