Texas Instruments TPS2813PWLE

Overview

TPS2813PWLE from Texas Instruments is a dual-channel complementary MOSFET driver IC with one inverting and one noninverting output stage, 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 TPS2813PWLE datasheet, TPS2813PWLE pinout, TPS2813PWLE application, or TPS2813PWLE equivalent, key selection criteria include complementary logic configuration, internal regulator support for 14–40-V input rails, fast switching with <40-ns propagation delay, and TSSOP-8 package compatibility with space-constrained power stages.

Technical Context

The TPS2813PWLE integrates two independent CMOS-input drivers-one inverting, one noninverting-enabling direct complementary control of high-side and low-side N-MOSFETs without external logic inversion. Its internal linear regulator accepts 14–40 V on REG_IN and delivers 10–13 V at up to 20 mA on REG_OUT to stabilize V_CC under wide-input conditions.

Each output uses a bipolar-MOSFET parallel structure to achieve rail-to-rail swing (0 V to V_CC) with 2-A instantaneous drive, ensuring reliable 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 during input transitions.

FAQ

What is the function of the REG_IN and REG_OUT pins on the TPS2813PWLE?

The REG_IN pin accepts an input voltage from 14 V to 40 V and feeds the internal linear regulator, which delivers a regulated 10–13 V output at REG_OUT capable of supplying up to 20 mA. This allows the TPS2813PWLE to operate directly from higher bus voltages while maintaining safe V_CC levels for the driver core and connected MOSFET gates. When unused, both REG_IN and REG_OUT may be left floating or tied together to V_CC/GND.

Can the TPS2813PWLE drive both high-side and low-side N-channel MOSFETs in a half-bridge configuration?

Yes, the TPS2813PWLE is explicitly designed for this role: its 1IN/1OUT path is noninverting (for low-side drive), and its 2IN/2OUT path is inverting (for high-side drive), enabling direct complementary control without external logic. The matched propagation delays (<5 ns skew) and 2-A peak current ensure synchronized switching and robust gate charging/discharging in half-bridge topologies.

What is the maximum load capacitance the TPS2813PWLE can drive while maintaining specified rise/fall times?

The TPS2813PWLE is characterized for 1-nF load capacitance with 25-ns max rise/fall times at V_CC = 14 V. At 10-nF load, rise/fall times increase significantly (to ~50 ns), but remain functional. For optimal performance, keep total gate capacitance (including Miller effect) ≤5 nF; for larger loads, paralleling both outputs (1OUT + 2OUT) reduces effective rise time by ~30%, as verified in TI's Application Report SLVS132F.

Does the TPS2813PWLE require external decoupling capacitors, and if so, what values are recommended?

Yes: a 0.1-µF ceramic capacitor must be placed between V_CC and GND, with short traces, to supply instantaneous current during fast switching. Additionally, when using the internal regulator, a 0.1-µF ceramic capacitor is required between REG_OUT and GND for stability, and a 4.7-µF electrolytic capacitor is recommended on REG_OUT for improved transient response-per TI's SLVS132F design guidelines.

How does the TPS2813PWLE prevent shoot-through current during input transitions?

The TPS2813PWLE minimizes shoot-through via Schmitt-trigger inputs (providing ≥1.2 V hysteresis) and an internal architecture that inherently limits cross-conduction. Measured shoot-through current remains <6 mA during input transitions-even when biased mid-rail-due to controlled pre-drive timing and bipolar-MOSFET output stage sequencing, as confirmed in Figures 17–18 of the SLVS132F datasheet.
