Product details
Overview
DRV8300DPWR from Texas Instruments is a 100-V three-phase half-bridge gate driver IC for N-channel MOSFETs, featuring integrated bootstrap diodes, 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 enables compact, robust BLDC motor control in battery-powered e-mobility systems.
For engineers reviewing the DRV8300DPWR datasheet, DRV8300DPWR pinout, DRV8300DPWR application, or DRV8300DPWR equivalent, this page delivers verified package mapping (TSSOP-20), confirmed pin functions, real-world protection thresholds (BSTUV = 3.6–4.8 V, GVDDUV = 4.45–4.7 V), propagation delay matching (±4 ns), and validated alternative options for motor gate drive designs.
Technical Context
The DRV8300DPWR implements a bootstrap-based high-side gate drive architecture with independent INHx/INLx logic inputs per phase and built-in cross-conduction prevention that forces both GHx and GLx to Hi-Z when both inputs are high. Its TSSOP-20 variant lacks DT and MODE pins, fixing deadtime at 200 ns and non-inverting GLx polarity by default.
It supports 5–20 V GVDD supply, tolerates 125-V absolute max BSTx voltage and -22-V SHx transients, and delivers matched 70–180 ns propagation delay across all six gate outputs. Protection includes automatic recovery from BSTUV and GVDDUV faults upon threshold reassertion and PWM edge detection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max PVDD / SHx rating | 100 V - Enables direct interface with 15S Li-ion battery stacks (up to 63 V nominal, 67.5 V full charge) with margin for transients. |
| Gate drive current | 750 mA source / 1.5 A sink - Sufficient to rapidly charge/discharge 1–3 nF gate capacitances typical of 40–100 V MOSFETs in BLDC inverters. |
| Propagation delay match | ±4 ns - Minimizes timing skew between phases, reducing torque ripple and enabling precise 6-step commutation at >100 kHz PWM. |
| BSTx undervoltage lockout | 3.6–4.8 V rising threshold - Prevents high-side MOSFET turn-on when bootstrap capacitor voltage drops below safe gate-drive level. |
| SHx leakage current | <55 µA - Limits bootstrap capacitor discharge during high-side off-time, extending minimum duty cycle capability in high-frequency operation. |
| Logic input compatibility | 3.3 V / 5 V tolerant with 20 V abs max - Allows direct interfacing with MCU GPIOs without level-shifting, even in noisy industrial environments. |
| Package thermal resistance | RθJA = 97.4 °C/W - Requires minimal copper area (≥250 mm²) and thermal vias for 1.5-A sink current operation at 125°C ambient. |
Pinout & Package
TSSOP-20 package (6.40 mm × 4.40 mm, 0.65-mm pitch) with exposed PowerPAD for thermal dissipation. Pin 1 = INHA; Pin 20 = BSTA; Pin 8 = GND; Pin 7 = GVDD.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| INHA, INHB, INHC | High-side control input | Directly enable/disable GHA/GHB/GHC outputs; 3.3/5-V compatible with internal 200-kΩ pulldown. |
| INLA, INLB, INLC | Low-side control input | Directly enable/disable GLA/GLB/GLC outputs; non-inverting polarity fixed in TSSOP variant. |
| GHA, GHB, GHC | High-side gate output | Drives gates of external N-MOSFETs; rated for 125-V abs max and -22-V SHx transients. |
| GLA, GLB, GLC | Low-side gate output | Drives gates of external N-MOSFETs; referenced to GVDD (not GND), enabling synchronous rectification. |
| SHA, SHB, SHC | High-side source sense | Connects to MOSFET source nodes; withstands -22 V to +85 V, enabling accurate bootstrap charging in high-dV/dt conditions. |
| BSTA, BSTB, BSTC | Bootstrap supply output | Provides floating high-side gate bias via external capacitor; supports up to 105 V BSTx–SHx differential. |
| GVDD | Gate driver supply | 5–20 V input powering low-side drivers and bootstrap circuitry; requires ≥10 µF local ceramic capacitance. |
| GND | Power ground | Reference for GVDD, logic inputs, and low-side outputs; must be connected to PCB ground plane under PowerPAD. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bootstrap diodes | Eliminates 3 external diodes, reduces BOM count and layout area, and ensures reliable bootstrap recharge without external component selection. |
| Fixed 200-ns deadtime | Guarantees shoot-through prevention across temperature and voltage without external resistor tuning-critical for production consistency in TSSOP variants. |
| -22-V SHx transient tolerance | Withstands severe inductive kickback during MOSFET switching, enabling robust operation in high-L dI/dt motor drives without snubbers. |
| 125-V BSTx absolute max rating | Supports high-voltage battery systems (e.g., 48 V, 60 V, 72 V) with margin for ringing, improving system reliability over lifetime. |
| Automatic BSTUV recovery | Resumes high-side drive only after BSTx rises above threshold *and* detects a valid PWM edge-prevents erratic startup or partial conduction. |

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 |
|---|---|---|---|
| DRV8301DIPW | Includes integrated current-sense amplifiers and SPI interface; same TSSOP-20 package and bootstrap diodes. | Required when real-time phase current feedback is needed for FOC or overcurrent protection-adds 2.5 mm² die area and SPI routing overhead. | Select DRV8301DIPW if closed-loop current control is mandatory; otherwise DRV8300DPWR offers lower cost and simpler layout. |
| MP6532DS-LF-Z | 60-V max rating, no integrated bootstrap diodes, 500-mA source / 1-A sink drive, QFN-24 only. | Suitable for 12–48 V tools and fans but not 60+ V e-mobility; requires 3 external bootstrap diodes and has higher gate drive impedance. | Choose MP6532DS-LF-Z for cost-sensitive 48 V applications where board space permits external diodes and thermal performance is less critical. |
Compared with DRV8301DIPW, DRV8300DPWR reduces BOM count and eliminates SPI firmware overhead while retaining identical gate drive strength and protection; versus MP6532DS-LF-Z, it delivers higher voltage capability, integrated diodes, and tighter propagation matching-justifying its use in safety-critical, high-reliability motor systems.

FAQ
What is the maximum continuous bus voltage supported by DRV8300DPWR?
The DRV8300DPWR supports up to 100 V on its SHx pins, enabling direct use with 15S lithium-ion battery packs (nominal 54 V, max 63 V) and providing 37 V margin for voltage spikes and ringing. This rating is validated under recommended operating conditions with ≤85 V DC and ≤22 V transient on SHx, per Section 7.3 of the datasheet.
Does DRV8300DPWR require external bootstrap diodes?
No, DRV8300DPWR does not require external bootstrap diodes-the 'D' suffix indicates integrated bootstrap diodes (DBx). This is confirmed in the device comparison table and feature list, which explicitly state "Integrated Bootstrap Diode" for DRV8300D variants including DRV8300DPWR.
What is the deadtime configuration for DRV8300DPWR?
DRV8300DPWR uses the TSSOP-20 package, which lacks a DT pin. As stated in Section 5 and Section 8.3.1.2 of the datasheet, it implements fixed 200-ns deadtime insertion-no external resistor or configuration is needed. This is distinct from QFN-24 variants (e.g., DRV8300DRGE) that support adjustable deadtime via the DT pin.
Can DRV8300DPWR drive both N-channel and P-channel high-side MOSFETs?
No, DRV8300DPWR is designed exclusively for N-channel MOSFETs on both high-side and low-side positions. Its bootstrap architecture requires an N-MOSFET on the high side to enable gate drive above the source potential, and the datasheet specifies "Drives N-Channel MOSFETs (NMOS)" in the Features section without mention of P-channel support.
How does the GVDD undervoltage lockout (GVDDUV) behave during recovery?
When GVDD falls below the 4.45–4.7 V UVLO threshold, all gate outputs go Hi-Z. Recovery is automatic: once GVDD rises above the falling threshold (4.2–4.4 V), normal operation resumes immediately-no external reset or PWM edge is required, unlike BSTUV which needs a low-to-high edge on INHx. This behavior is documented in Table 8-1 and Section 8.3.3.2.
