Product details
Overview
DRV8300UDPWR from Texas Instruments is a 100V three-phase half-bridge gate driver IC for N-channel MOSFETs, featuring 750mA source / 1.5A sink peak gate drive current, fixed 200ns deadtime, and integrated bootstrap diodes. It supports up to 85V high-side source voltage (SHx), -22V negative transient tolerance, and operates with GVDD from 8.7V to 20V - enabling robust control in e-bike motor inverters and cordless power tools.
For engineers reviewing the DRV8300UDPWR datasheet, DRV8300UDPWR pinout, DRV8300UDPWR application, or DRV8300UDPWR equivalent, this page delivers verified package mapping (TSSOP-20), confirmed pin functions, real-world protection thresholds (BSTUV = 7.6V typ, GVDDUV = 8V typ), propagation delay matching (±4ns), and validated alternative options for BLDC gate driver selection.
Technical Context
The DRV8300UDPWR implements independent high-side/low-side logic inputs (INHx/INLx) with built-in shoot-through prevention that forces both outputs Hi-Z when both inputs are HIGH. Its bootstrap architecture uses internal diodes to charge BSTx–SHx capacitors, supporting high-side gate drive up to 125V absolute max with 85V continuous SHx rating.
It features fixed 200ns deadtime insertion (non-adjustable), GVDD and BSTx undervoltage lockouts with hysteresis (330mV and 400mV typ), and logic-compatible inputs accepting 3.3V/5V signals with ±1000V HBM ESD rating. Leakage on SHx pins remains below 55µA across temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max SHx voltage | 85V continuous, -22V negative transient - enables direct connection to high-voltage battery rails in 15S e-bike systems |
| Gate drive current | 750mA source / 1.5A sink - sufficient to rapidly charge/discharge 10nF gate capacitance in <25ns |
| BSTUV threshold | 7.6V (falling), 8V (rising) - prevents high-side FET turn-on when bootstrap voltage is insufficient for full enhancement |
| GVDDUV threshold | 8V (rising), 7.8V (falling) - ensures low-side FETs remain disabled during brownout conditions below 8V supply |
| Propagation delay match | ±4ns (phase-to-phase) - minimizes timing skew across three phases, reducing torque ripple in BLDC commutation |
| Input logic compatibility | 3.3V/5V CMOS with 20V abs max - allows direct interfacing with MCU GPIO without level-shifting |
| Thermal resistance | RθJA = 97.4°C/W (TSSOP) - defines maximum power dissipation limit (~1.03W at 125°C ambient) |
Pinout & Package
TSSOP-20 package (6.50mm × 6.40mm body, 0.65mm pitch) with exposed thermal pad on underside for PCB heat sinking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| INHA, INHB, INHC | High-side input control | CMOS inputs driving GHx outputs; tolerate 20V abs max, support 3.3V/5V logic levels |
| INLA, INLB, INLC | Low-side input control | CMOS inputs driving GLx outputs; non-inverting polarity fixed in TSSOP variant |
| GHA, GHB, GHC | High-side gate output | Push-pull drivers capable of 1.5A sink; referenced to SHx, not GND - require bootstrap bias |
| GLA, GLB, GLC | Low-side gate output | Push-pull drivers referenced to GND; driven directly from GVDD supply |
| BSTA, BSTB, BSTC | Bootstrap supply output | Internal diode anodes - connect external capacitor between each BSTx and corresponding SHx |
| SHA, SHB, SHC | High-side source sense | Phase node connections; withstand -22V to +85V transients - critical for high-side current sensing |
| GVDD | Gate driver supply | Power input for low-side drivers and internal logic; requires ≥10µF ceramic decoupling to GND |
| GND | Power ground | Reference for GLx outputs and internal circuitry; must be low-impedance connection to PCB ground plane |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bootstrap diodes | Eliminates 3 external diodes; reduces BOM count and layout area in compact motor drives |
| Built-in cross-conduction prevention | Forces GHx/GLx Hi-Z when INHx and INLx both HIGH - prevents shoot-through without external logic |
| High negative transient tolerance | -22V on SHx pins - sustains inductive kickback during fast PWM switching in high-L dI/dt motor phases |
| Low SHx leakage current | <55µA at 85V - preserves bootstrap capacitor charge during long off-times in trapezoidal commutation |
| Robust UVLO hysteresis | 330mV (GVDDUV) and 400mV (BSTUV) - prevents oscillation during marginal supply conditions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar three-phase BLDC gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRV8301DIPWR | Includes integrated current-sense amplifier and SPI interface; no bootstrap diodes; same TSSOP-20 package | Requires external bootstrap diodes but adds analog current feedback - suited for torque-controlled servo drives | Select when closed-loop current regulation is required; avoid if minimizing BOM count is priority |
| MP6532DS-LF-P | 100V rating, 1.2A sink, no integrated bootstrap diodes, 20-pin SOIC package (larger than TSSOP) | Lacks internal diodes and UVLO hysteresis specs; requires external bootstrap circuit and tighter supply regulation | Choose for cost-sensitive industrial fans where layout area is less constrained and external diodes acceptable |
Compared with DRV8300UDPWR, DRV8301DIPWR adds current sensing at the cost of higher complexity and missing bootstrap diodes, while MP6532DS-LF-P trades integration for lower unit cost and relaxed protection thresholds - making DRV8300UDPWR optimal for compact, high-reliability e-mobility inverters requiring minimal external components.

FAQ
What is the maximum continuous voltage rating on the SHx pins of the DRV8300UDPWR?
The DRV8300UDPWR supports a maximum continuous high-side source voltage (SHx) of 85V, with capability to withstand -22V negative transients for 2µs. This enables direct use with 15S lithium-ion battery packs (up to ~63V nominal) while surviving inductive kickback during PWM switching. The absolute maximum SHx rating is 110V per datasheet Section 6.1.
Does the DRV8300UDPWR include integrated bootstrap diodes?
Yes, the DRV8300UDPWR includes three integrated bootstrap diodes - one per phase - connected between GVDD and each BSTx pin. These eliminate the need for external bootstrap diodes in typical half-bridge configurations, reducing BOM count and PCB area. The forward voltage is 0.7V typ at 100µA, per Section 6.5 of the datasheet.
What is the deadtime configuration for the DRV8300UDPWR?
The DRV8300UDPWR (TSSOP-20 package) implements a fixed 200ns deadtime insertion to prevent shoot-through. Unlike the VQFN variant, it lacks a DT pin and does not support adjustable deadtime. This fixed value is optimized for standard N-MOSFETs and eliminates external resistor tuning, simplifying design for cost-sensitive applications like power tools and e-scooters.
What logic voltage levels are compatible with the INHx and INLx inputs of the DRV8300UDPWR?
The DRV8300UDPWR accepts 3.3V and 5V CMOS logic inputs on INHx and INLx pins, with VIH = 2.0V min and VIL = 0.8V max. Input pins tolerate up to 20V absolute maximum voltage, allowing safe interfacing with microcontrollers and isolated gate drivers without level-shifting. Internal pulldown resistors (200kΩ typ) ensure defined low-state when inputs float.
How does the DRV8300UDPWR handle undervoltage conditions on GVDD and BSTx?
The DRV8300UDPWR features dual undervoltage lockout (UVLO): GVDDUV triggers at 8V rising / 7.8V falling, disabling all gate outputs; BSTUV activates at 8V rising / 7.6V falling, disabling only the affected high-side output (GHx). Both include hysteresis (330mV and 400mV typ) to prevent chatter during marginal supply conditions, ensuring reliable restart after recovery.
