Texas Instruments TPS2814P

Overview

TPS2814P from Texas Instruments is a dual 2-input AND gate MOSFET driver with one inverting input per channel, designed for high-speed gate driving of n-channel and p-channel power MOSFETs. It delivers 2-A peak output current at VCC = 14 V, achieves ≤25-ns rise/fall times and ≤40-ns propagation delay (1-nF load), and operates across −40°C to 125°C - enabling use in synchronous buck converters, motor drives, and industrial SMPS.

For engineers reviewing the TPS2814P datasheet, TPS2814P pinout, TPS2814P application, or TPS2814P equivalent, key selection criteria include its dual AND logic architecture with single inversion per driver, 4-V to 14-V supply range, ultra-low 5-µA quiescent supply current, and compatibility with high-capacitance gate loads up to 10 nF when paralleled.

Technical Context

The TPS2814P implements two independent AND-gate drivers, each accepting two inputs: one noninverting (1IN1/2IN1) and one inverting (1IN2/2IN2), producing outputs 1OUT = 1IN1 • 1IN2 and 2OUT = 2IN1 • 2IN2. Its CMOS input stage features Schmitt-trigger thresholds (~⅓VCC low-to-high, ~⅔VCC high-to-low) and <10-pF input capacitance, ensuring noise immunity and fast edge response.

The output stage uses a bipolar-MOSFET parallel structure to achieve rail-to-rail swing (0.18 V low-level / 9.9 V high-level at 1 mA) and 2-A instantaneous sourcing/sinking capability. Unlike TPS2811–TPS2813, it omits the internal regulator - simplifying biasing but restricting operation to 4–14 V on VCC without external regulation.

Key Specifications

Pinout & Package

FAQ

What logic function does the TPS2814P implement, and how does it differ from TPS2811–TPS2813?

The TPS2814P implements dual 2-input AND gates, each with one noninverting and one inverting input (1OUT = 1IN1 • 1IN2; 2OUT = 2IN1 • 2IN2). Unlike TPS2811–TPS2813, it lacks an internal regulator - limiting VCC to 4–14 V and removing REG_IN/REG_OUT pins. This simplifies supply design but excludes direct operation from 14–40 V unregulated rails. The TPS2814P is optimized for logic-integrated gate control rather than regulated high-voltage biasing.

Can the TPS2814P drive both high-side and low-side N-channel MOSFETs in a half-bridge configuration?

Yes, the TPS2814P can drive both high-side and low-side N-channel MOSFETs in a half-bridge, provided appropriate level-shifting or bootstrap circuitry is used for the high-side gate. Its dual independent AND logic allows precise dead-time insertion: for example, 1IN1 and 2IN1 can receive complementary PWM signals, while 1IN2 and 2IN2 accept inverted enable signals to enforce minimum off-time. The 2-A peak output ensures fast gate charging even with >1000-pF effective gate capacitance.

What decoupling capacitors are required for stable operation of the TPS2814P?

A 0.1-µF ceramic capacitor must be placed between VCC and GND, with leads as short as possible (<5 mm), directly at the TPS2814P pins. This provides instantaneous current during fast switching transitions. For systems with high ripple or long supply traces, add a bulk 4.7-µF electrolytic (or tantalum) capacitor near the 0.1-µF device. No capacitor is required on unused pins; GND must be solidly connected to the system ground plane to minimize shoot-through and EMI.

Does the TPS2814P support paralleling its two outputs to drive a single large MOSFET?

Yes - the TPS2814P supports safe paralleling of 1OUT and 2OUT to drive a single high-capacitance MOSFET gate. Its matched propagation delay (<1 ns skew) and identical output structure minimize circulating current. Application data shows paralleled outputs reduce 10-nF rise time by ~35% vs single-channel drive. Ensure both outputs share identical trace length and termination; do not parallel outputs across multiple TPS2814P units due to process variation-induced timing mismatch.

What is the maximum gate capacitance the TPS2814P can reliably drive at 500-kHz switching frequency?

At 500 kHz, the TPS2814P reliably drives up to 4.7 nF total gate capacitance per channel while maintaining <10% duty-cycle distortion and <100°C junction temperature (with 1090-mW P-package derating). This corresponds to MOSFETs with Qg ≈ 65 nC at 10 V (e.g., IRF530). For >4.7 nF, paralleling both outputs or adding a small gate resistor (≤5 Ω) improves stability and reduces ringing without compromising switching speed.
