Texas Instruments TPS2813PWG4

Overview

TPS2813PWG4 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 (VCC = 14 V, CL = 1 nF), and integrated 10–13-V regulator for input supply extension up to 40 V. It operates across −40°C to 125°C and targets high-frequency synchronous buck, half-bridge, and motor gate-drive applications.

For engineers reviewing the TPS2813PWG4 datasheet, TPS2813PWG4 pinout, TPS2813PWG4 application, or TPS2813PWG4 equivalent, this page delivers verified functional identity, regulator-enabled high-voltage operation, complementary logic configuration, thermal-rated TSSOP-8 package data, and validated alternatives for gate-driver selection in power-conversion designs.

Technical Context

The TPS2813PWG4 integrates two independent drivers - Channel 1 inverts input signal, Channel 2 buffers it noninverting - enabling direct complementary drive of high-side/low-side N-channel MOSFETs without external logic. Its internal regulator accepts 14–40 V on REG_IN and delivers 10–13 V at up to 20 mA to stabilize VCC under wide-input conditions.

Each output uses a bipolar-MOSFET parallel stage to achieve rail-to-rail swing (0.18 V low-level, 9.9 V high-level at 10 V VCC) and minimize shoot-through current (<6 mA). Input thresholds follow Schmitt-trigger behavior (≈1/3 VCC low-to-high, ≈2/3 VCC high-to-low), ensuring noise immunity and consistent timing regardless of input slew rate.

FAQ

What is the function of the REG_IN and REG_OUT pins on the TPS2813PWG4?

The REG_IN pin accepts an unregulated input voltage from 14 V to 40 V and feeds the internal regulator, which produces a stable 10–13 V output on REG_OUT. This regulated voltage is intended to power the VCC pin, allowing the TPS2813PWG4 to operate safely from high-input rails without external regulation. When not used, both REG_IN and REG_OUT may be left floating or tied together to VCC or GND.

Can the TPS2813PWG4 drive both high-side and low-side N-channel MOSFETs in a half-bridge configuration?

Yes - the TPS2813PWG4 is explicitly configured for this role: its Channel 1 (1IN → 1OUT) is inverting, and Channel 2 (2IN → 2OUT) is noninverting. When driven by a single PWM signal, it generates complementary gate-drive waveforms ideal for N-channel half-bridges. The matched propagation delay (≤40 ns) and fast edges (≤25 ns) minimize shoot-through risk without requiring external dead-time circuitry.

What is the maximum continuous output current rating for each driver channel of the TPS2813PWG4?

The TPS2813PWG4 is rated for ±100 mA continuous output current per channel (1OUT and 2OUT), as specified in Absolute Maximum Ratings. Its 2-A peak current capability applies only to short-duration gate-charge pulses (e.g., <100 ns), not steady-state loads. For sustained current demands beyond ±100 mA, external buffering or paralleling is required - though typical MOSFET gate drive remains well within peak-current limits.

How does the TPS2813PWG4 achieve rail-to-rail output voltage swing?

The TPS2813PWG4 uses a unique parallel-output stage combining bipolar transistors and MOSFETs per channel. This hybrid architecture allows the output to swing within 0.18 V of GND (low-level) and within 0.1 V of VCC (high-level) at 10 V supply - significantly tighter than standard CMOS or bipolar-only drivers. This ensures full enhancement of low-threshold MOSFETs and robust turn-off even under heavy capacitive loading.

Is the TPS2813PWG4 pin-compatible with other members of the TPS28xx family such as the TPS2811 or TPS2812?

Yes - all TPS28xx variants in the PW (TSSOP-8), D (SOIC-8), and P (PDIP-8) packages share identical pinouts and footprints. The TPS2813PWG4 differs only in logic function (complementary outputs), while TPS2811 (dual inverting) and TPS2812 (dual noninverting) retain the same REG_IN, REG_OUT, VCC, GND, and I/O pin assignments - enabling drop-in replacement where logic configuration matches system requirements.
