Texas Instruments TPS2813PWR

Overview

TPS2813PWR from Texas Instruments is a dual complementary MOSFET driver IC with one inverting and one noninverting output channel, 2-A peak source/sink current capability, 25-ns max rise/fall times (V_CC = 14 V, C_L = 1 nF), integrated 10–13-V regulator (REG_IN to REG_OUT), and −40°C to 125°C operating range. It drives high-side/low-side N-channel MOSFETs in synchronous buck converters and motor gate drivers.

For engineers reviewing the TPS2813PWR datasheet, TPS2813PWR pinout, TPS2813PWR application, or TPS2813PWR equivalent, key selection criteria include regulator-enabled high-voltage input tolerance (up to 40 V), complementary logic configuration for half-bridge control, low 5-µA quiescent supply current, and fast propagation delay (≤40 ns) under load.

Technical Context

The TPS2813PWR integrates two independent CMOS-input drivers - one inverting, one noninverting - enabling direct half-bridge gate drive without external logic inversion. Its internal linear regulator accepts 14–40 V on REG_IN and delivers a stable 10–13 V at REG_OUT (up to 20 mA), decoupling V_CC from high bus voltages.

Each output stage combines bipolar and MOSFET transistors in parallel to achieve rail-to-rail swing (0 V to V_CC) with 2-A instantaneous current, ensuring robust turn-on/turn-off of low-threshold MOSFETs. Input thresholds are Schmitt-triggered (≈1/3 V_CC low, ≈2/3 V_CC high), providing noise immunity and shoot-through current <6 mA.

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

Compared with TPS2813D, the TPS2813PWR offers superior thermal performance in space-constrained designs due to its smaller TSSOP-8 footprint and lower junction-to-ambient resistance; versus UCC27524ADRV, it trades raw speed for integrated voltage regulation and complementary logic - reducing external component count in mid-power industrial SMPS.

FAQ

What is the function of the REG_IN and REG_OUT pins on the TPS2813PWR?

The REG_IN pin accepts an input voltage from 14 V to 40 V and feeds the internal linear regulator. The REG_OUT pin delivers a regulated 10–13 V output capable of supplying up to 20 mA. In the TPS2813PWR, this regulated voltage typically powers the V_CC pin, enabling safe operation from high bus voltages while protecting the driver core and MOSFET gates from overvoltage.

Can the TPS2813PWR drive both high-side and low-side N-channel MOSFETs in a half-bridge configuration?

Yes - the TPS2813PWR is explicitly configured for half-bridge gate drive: its 1IN/1OUT pair is inverting, and its 2IN/2OUT pair is noninverting. This complementary logic allows direct connection to high-side and low-side N-channel MOSFETs without external inverters, provided proper dead-time control is implemented externally or via controller timing.

What is the maximum capacitive load the TPS2813PWR can drive while maintaining 25-ns rise time?

The 25-ns max rise time specification for the TPS2813PWR is guaranteed with a 1-nF load at V_CC = 14 V. With larger loads (e.g., 10 nF), rise/fall times increase significantly (to ~50 ns), as confirmed in Figures 25–26 of the datasheet. For >1-nF loads, paralleling both outputs is recommended to maintain speed.

Does the TPS2813PWR require external decoupling capacitors, and if so, what values?

Yes - a 0.1-µF ceramic capacitor is required between V_CC and GND to supply instantaneous current during fast switching. Additionally, when using the regulator, a 0.1-µF ceramic capacitor must be placed between REG_OUT and GND for stability, and a 4.7-µF electrolytic capacitor is recommended on REG_OUT for improved transient response.

How does the TPS2813PWR minimize shoot-through current during input transitions?

The TPS2813PWR uses a Schmitt-trigger input stage with ≈1.2 V hysteresis (at V_CC = 5 V) and an internally optimized predriver design that limits shoot-through current to <6 mA during input transitions - verified in Figures 17 and 18 of the datasheet. This reduces power loss and thermal stress compared to standard CMOS drivers.
