Product details
Overview
DRV8300NPWR from Texas Instruments is a 100-V three-phase half-bridge gate driver IC for N-channel MOSFETs, featuring 750-mA source / 1.5-A sink peak gate drive current, fixed 200-ns deadtime, and -22-V negative transient tolerance on SHx pins. It supports 5–20-V GVDD supply and drives BLDC/PMSM motors in battery-powered e-mobility systems up to 15S.
For engineers reviewing the DRV8300NPWR datasheet, DRV8300NPWR pinout, DRV8300NPWR application, or DRV8300NPWR equivalent, this page delivers verified package mapping (TSSOP-20), confirmed bootstrap-less architecture, validated protection thresholds (BSTUV = 3.6–4.8 V, GVDDUV = 4.45–4.7 V), and real-world timing specs including ±4-ns propagation delay matching and 125-ns typical tPD.
Technical Context
The DRV8300NPWR implements independent high-side/low-side control with integrated shoot-through prevention logic that forces both GHx and GLx into Hi-Z when INHx and INLx are simultaneously high. Its bootstrap architecture relies on external diodes and capacitors per phase (BSTA/SHB/SHC), eliminating internal diodes found in DRV8300D variants.
As a TSSOP-20 variant without MODE or DT pins, it defaults to non-inverting INLx polarity and fixed 200-ns deadtime insertion-unlike QFN-24 versions offering adjustable deadtime and polarity selection. All three phases share identical electrical characteristics: 10–24-ns rise time, 5–12-ns fall time, and <55-µA SHx leakage at 85 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max PVDD voltage | 100 V - Enables direct interface with 15S Li-ion battery stacks (up to ~63 V nominal, 67.5 V max). |
| Gate drive current | 750 mA source / 1.5 A sink - Sufficient to rapidly charge/discharge 10-nC gate charge MOSFETs at >20 kHz PWM. |
| SHx negative transient rating | -22 V - Withstands motor back-EMF spikes and inductive kickback without latch-up or damage. |
| BSTx absolute max voltage | 125 V - Supports high-voltage transients during fast switching in noisy motor drive environments. |
| Propagation delay match | ±4 ns - Minimizes phase-to-phase timing skew, reducing torque ripple and enabling precise field-oriented control. |
| GVDD UVLO threshold | 4.45–4.7 V rising - Prevents partial gate drive activation during brown-out, ensuring reliable MOSFET turn-off. |
| Bootstrap UVLO (BSTUV) | 3.6–4.8 V rising - Disables GHx output if bootstrap capacitor voltage drops below safe gate-drive level. |
Pinout & Package
TSSOP-20 package (6.40 mm × 4.40 mm) with exposed thermal pad; pin-compatible with DRV8300DIPW, DRV8300DPW, and DRV8300NIPW.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| BSTA, BSTB, BSTC | Bootstrap output | Drives external bootstrap capacitor connected to respective SHx pin; requires external diode (DRV8300N architecture). |
| GHA, GHB, GHC | High-side gate driver output | Direct connection to gates of high-side N-MOSFETs; rated for 125-V abs max and -22-V transient on SHx. |
| GLA, GLB, GLC | Low-side gate driver output | Drives low-side N-MOSFET gates using GVDD supply; supports 5–20 V logic-compatible drive levels. |
| INHA, INHB, INHC | High-side input control | CMOS-compatible inputs accepting 0–GVDD logic; no internal pull-up/down; require MCU-level drive. |
| INLA, INLB, INLC | Low-side input control | Non-inverting inputs with 200-kΩ internal pulldown; float-low default prevents unintended turn-on. |
| SHA, SHB, SHC | High-side source sense | Connects to MOSFET source nodes; tolerates -22 V to +85 V DC and 2-µs transients. |
| GVDD | Gate driver power supply | Supplies low-side drivers and internal logic; requires ≥10-µF X5R/X7R ceramic decoupling to GND. |
| GND | Power ground | Common reference for GVDD, logic inputs, and gate outputs; must be low-impedance PCB plane. |
Key Features
| Feature | Design Value |
|---|---|
| Fixed 200-ns deadtime | Hardware-enforced minimum off-time between GHx and GLx per phase prevents shoot-through without software overhead. |
| External bootstrap diode support | Enables use of ultra-low-VF Schottky diodes for higher efficiency and reduced heat in high-duty-cycle operation. |
| Robust SHx pin rating | -22 V to +85 V operating range allows direct connection to motor phase nodes in high-noise BLDC inverters. |
| Integrated UVLO protection | Dual lockout (GVDDUV + BSTUV) ensures gate drivers disable before MOSFETs enter linear region, preventing thermal runaway. |
| Low propagation delay mismatch | ±4 ns matching across all six gate outputs enables precise synchronous commutation in FOC and trapezoidal drives. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar three-phase gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRV8300DPW | Integrated bootstrap diodes; same TSSOP-20 package and fixed 200-ns deadtime. | Reduces external component count but increases thermal load on IC due to diode conduction losses. | Select DRV8300DPW when board space is constrained and thermal management permits internal diode dissipation. |
| DRV8300NRGE | VQFN-24 package with MODE and DT pins; supports adjustable deadtime (200–2000 ns) and inverting/non-inverting INLx. | Enables fine-tuned timing optimization for high-efficiency FOC or noise-sensitive audio applications. | Select DRV8300NRGE when design requires deadtime tuning or flexible logic polarity without changing MCU firmware. |
Compared with DRV8300DPW, the DRV8300NPWR trades integrated diodes for lower thermal stress and higher efficiency; compared with DRV8300NRGE, it sacrifices configurability for cost and footprint advantages in fixed-function motor drives.

FAQ
What is the bootstrap architecture used in DRV8300NPWR?
The DRV8300NPWR uses an external bootstrap architecture: each high-side driver (GHA/GHB/GHC) requires an external Schottky diode and capacitor between BSTx and SHx pins. Unlike DRV8300D variants, it does not integrate bootstrap diodes-this reduces die temperature and improves efficiency in high-duty-cycle operation. The DRV8300NPWR datasheet specifies 1-µF minimum CBOOT and recommends low-VF, fast-recovery diodes for optimal performance.
Does DRV8300NPWR support inverting logic for low-side inputs?
No, the DRV8300NPWR does not support configurable INLx polarity. As a TSSOP-20 variant without a MODE pin, it operates exclusively in non-inverting mode: GLx outputs follow INLx logic states directly. Inverting behavior is only available in QFN-24 variants (DRV8300N/DRV8300D RGE) via the MODE pin, or in dedicated TSSOP-20 parts like DRV8300NI.
What is the maximum allowable voltage on the SHx pins of DRV8300NPWR?
The DRV8300NPWR SHx pins (SHA, SHB, SHC) are rated for -22 V to +85 V DC under recommended operating conditions, with transient capability up to -22 V for 2 µs. This rating enables direct connection to motor phase nodes in 15S battery systems and withstands inductive kickback during abrupt current interruption-critical for reliable operation in e-mobility and power tool inverters.
How does the deadtime function in DRV8300NPWR differ from QFN-package variants?
The DRV8300NPWR implements fixed hardware deadtime of 200 ns (typical) with no external adjustment-unlike QFN-24 variants (DRV8300NRGE/DRV8300DRGE) that feature a DT pin for resistor-based deadtime tuning from 200 ns to 2000 ns. This fixed timing simplifies layout and firmware but limits optimization for specific MOSFET gate charge profiles or switching frequency targets.
What protection features are built into DRV8300NPWR?
The DRV8300NPWR integrates two independent undervoltage lockouts: GVDDUV (4.45–4.7 V rising threshold) disables all gate outputs during low-supply events, and BSTUV (3.6–4.8 V rising) disables individual GHx outputs if its BSTx–SHx voltage falls below safe gate-drive level. Both recover automatically upon threshold crossing plus a low-to-high edge on the corresponding INHx pin-ensuring fail-safe MOSFET control without external supervision circuitry.
