Texas Instruments TPS2813PE4

Overview

TPS2813PE4 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 TPS2813PE4 datasheet, TPS2813PE4 pinout, TPS2813PE4 application, or TPS2813PE4 equivalent, key selection criteria include its complementary logic configuration, internal regulator enabling 14–40-V input operation, fast propagation delay (<40 ns), low 5-µA supply current, and compatibility with high-capacitance gate loads up to 10 nF.

Technical Context

The TPS2813PE4 integrates two independent CMOS-input drivers - one inverting (1IN → 1OUT), one noninverting (2IN → 2OUT) - sharing a single V_CC rail and ground. Its internal linear regulator accepts 14–40 V at REG_IN and delivers 10–13 V at REG_OUT to power external circuitry or 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, minimizing shoot-through current (<6 mA) via Schmitt-trigger inputs with ~1.6-V hysteresis and thresholds at ~⅓V_CC (low) and ~⅔V_CC (high).

FAQ

What is the function of the REG_IN and REG_OUT pins on the TPS2813PE4?

The REG_IN pin accepts an unregulated input voltage from 14 V to 40 V and feeds Texas Instruments' internal linear regulator. The REG_OUT pin delivers a regulated 10–13 V output capable of supplying up to 20 mA. This allows the TPS2813PE4 to operate safely from high-voltage rails while powering its own V_CC or external bias circuitry - a key feature distinguishing the TPS2813PE4 from non-regulator variants like TPS2814/TPS2815.

Can the TPS2813PE4 drive both high-side and low-side N-channel MOSFETs in a half-bridge configuration?

Yes, the TPS2813PE4 is explicitly designed for this role: its complementary logic configuration - one inverting driver (1IN→1OUT) and one noninverting driver (2IN→2OUT) - generates naturally anti-phase gate signals ideal for half-bridge topologies. When paired with appropriate bootstrap or isolated gate-drive circuitry for the high-side MOSFET, the TPS2813PE4 ensures precise timing alignment and 2-A peak current delivery to both gates.

What is the maximum capacitive load the TPS2813PE4 can drive while maintaining specified rise/fall times?

The TPS2813PE4 is characterized for 1-nF load with 25-ns max rise/fall times at V_CC = 14 V. Application data shows usable performance up to 10-nF loads, though rise/fall times degrade to ~40–50 ns. For loads exceeding 10 nF, paralleling both outputs (1OUT and 2OUT) is recommended - this reduces effective gate resistance and improves edge speed, as verified in Figures 28–31 of the SLVS132F datasheet.

Does the TPS2813PE4 require external decoupling capacitors, and if so, what values are recommended?

Yes, TI specifies two mandatory decoupling networks: a 0.1-µF ceramic capacitor between V_CC and GND (placed close to pins 6 and 3), and a 0.1-µF ceramic + 4.7-µF electrolytic pair between REG_OUT and GND (pins 8 and 3). These suppress high-frequency transients and ensure regulator stability - omitting them risks oscillation, excessive shoot-through, or premature device failure under dynamic load conditions.

How does the input hysteresis of the TPS2813PE4 improve system reliability in noisy environments?

The TPS2813PE4 features Schmitt-trigger inputs with ~1.6-V hysteresis (at V_CC = 5 V), meaning the rising threshold is ~⅔V_CC and falling threshold is ~⅓V_CC. This prevents multiple output toggles caused by slow-rising or noisy input edges - a common issue in high-dv/dt power stages. As confirmed in Figures 17–18, this design limits shoot-through current to <6 mA during input transitions, directly enhancing thermal margin and long-term reliability.
