Texas Instruments TPS2813P

Overview

TPS2813P from Texas Instruments is a dual complementary MOSFET driver IC with one inverting and one noninverting channel, 2-A peak output current at VCC = 14 V, 25-ns max rise/fall time (1-nF load), and integrated 11.5-V regulator supporting 14–40-V REG_IN input. It operates across −40°C to 125°C and targets high-frequency synchronous buck converters and half-bridge gate drive.

For engineers reviewing the TPS2813P datasheet, TPS2813P pinout, TPS2813P application, or TPS2813P equivalent, key selection criteria include regulator-enabled high-voltage operation (up to 40 V), complementary output logic configuration, fast switching under capacitive loads, and thermal robustness in industrial power stages.

Technical Context

The TPS2813P integrates two independent CMOS-input drivers-one inverting, one noninverting-enabling direct complementary control of high-side/low-side N-channel MOSFETs without external logic inversion. Its internal regulator accepts 14–40 V on REG_IN and delivers a stable 11.5-V output (±1.5 V) to power VCC, allowing safe operation with wide-input DC supplies.

Each output stage uses a bipolar-MOSFET parallel structure to achieve rail-to-rail swing (0 V to VCC) with 2-A peak sourcing/sinking capability, minimizing shoot-through current (<6 mA) via Schmitt-trigger inputs and optimized predrive timing. Propagation delay remains ≤40 ns across 5–14 V VCC range with 1-nF load.

Key Specifications

Pinout & Package

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual complementary MOSFET driver applications.

Compared with TPS2813D, the TPS2813P offers superior thermal dissipation (1090 mW vs 730 mW) in through-hole form, while UCC27324 trades regulator integration for higher drive strength and noninverting-only outputs-making it unsuitable for direct complementary replacement without added circuitry.

FAQ

What is the function of the REG_IN and REG_OUT pins on the TPS2813P?

The REG_IN pin accepts 14–40 V input to power the internal regulator, which delivers a stable 11.5-V output at REG_OUT to supply VCC. This allows the TPS2813P to operate safely from high-voltage rails without external regulation. When unused, both REG_IN and REG_OUT may be left disconnected or tied together to VCC or GND.

Can the TPS2813P drive both high-side and low-side N-channel MOSFETs in a synchronous buck converter?

Yes - the TPS2813P's complementary logic (one inverting, one noninverting output) enables direct gate drive of high-side and low-side N-channel MOSFETs without external inverters or level shifters. Its rail-to-rail output swing and 2-A peak current ensure fast, robust switching in buck topologies up to 500 kHz.

What is the maximum capacitive load the TPS2813P can drive while maintaining 25-ns rise time?

The 25-ns max rise time is specified with a 1-nF load at VCC = 14 V. For larger loads (e.g., 10-nF), rise time degrades to ~60 ns (per datasheet Fig. 25), but paralleling both outputs reduces effective rise time by ~30%. Always use local 0.1-µF ceramic + 4.7-µF bulk capacitance at VCC and REG_OUT.

Does the TPS2813P require external components for stable regulator operation?

Yes - a 0.1-µF ceramic capacitor between REG_OUT and GND is mandatory for regulator stability. For optimal transient response, add a 4.7-µF electrolytic capacitor on REG_OUT and a 0.1-µF ceramic capacitor on REG_IN. These prevent oscillation and support 20-mA regulator output under dynamic load.

How does the TPS2813P minimize shoot-through current during input transitions?

The TPS2813P uses Schmitt-trigger inputs with ≥1.2 V hysteresis and a front-end design that inherently limits shoot-through current to <6 mA during mid-rail input transitions (per Fig. 17–18). This is achieved without external timing resistors and maintains reliability in high-dV/dt power environments.
