Texas Instruments DRV8300NRGER

Overview

DRV8300NRGER 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, adjustable deadtime via DT pin, and robust -22-V SHx transient tolerance. It enables high-efficiency BLDC motor control in battery-powered e-mobility systems.

For engineers reviewing the DRV8300NRGER datasheet, DRV8300NRGER pinout, DRV8300NRGER application, or DRV8300NRGER equivalent, this page delivers verified package mapping (24-pin VQFN, 4.0 × 4.0 mm), confirmed bootstrap architecture with external diode requirement, real propagation delay matching (±4 ns), validated protection thresholds (BSTUV: 4.2 V, GVDDUV: 4.6 V), and precise DT-resistor-based deadtime tuning range (200–2000 ns).

Technical Context

The DRV8300NRGER implements independent high-side/low-side gate drivers per phase using bootstrap voltage generation-requiring external bootstrap diodes and capacitors-enabling operation up to 100-V PVDD with 125-V absolute BSTx rating. Its DT pin allows linear deadtime adjustment (200–2000 ns) to prevent shoot-through in high-dV/dt motor phases.

It supports both inverting and non-inverting low-side logic inputs via MODE pin configuration, provides ±4 ns propagation delay matching across phases, and integrates BSTUV and GVDDUV lockouts with automatic recovery triggered by PWM edges or supply restoration.

FAQ

What is the key distinction between DRV8300NRGER and DRV8300DRGE?

The DRV8300NRGER requires external bootstrap diodes and capacitors, offering greater thermal separation and layout flexibility, while the DRV8300DRGE integrates bootstrap diodes on-chip. Both share identical VQFN-24 packaging, pinout, and electrical specifications including 100-V PVDD rating, ±4 ns propagation delay matching, and DT pin-based deadtime adjustment - making DRV8300NRGER preferable for thermally demanding applications where diode self-heating must be minimized.

Does DRV8300NRGER support both inverting and non-inverting low-side logic inputs?

Yes, DRV8300NRGER supports both configurations via its MODE pin: when left floating, INLx inputs operate in non-inverting mode (GLx follows INLx); when tied to GVDD, they operate in inverting mode (GLx opposes INLx). This eliminates the need for external inverters and ensures compatibility with diverse MCU PWM output architectures, including center-aligned and complementary PWM generators used in advanced motor control algorithms.

What is the maximum recommended deadtime adjustment range for DRV8300NRGER?

The DRV8300NRGER supports deadtime adjustment from 200 ns to 2000 ns using a resistor between the DT pin and GND. A 40 kΩ resistor yields ~200 ns, while 400 kΩ yields ~2000 ns. The DT pin must not be left floating in production designs - doing so defaults to fixed 200 ns deadtime, which may be insufficient for slower MOSFETs or high-temperature operation where gate threshold drift increases shoot-through risk.

How does DRV8300NRGER handle undervoltage conditions on BSTx and GVDD rails?

DRV8300NRGER features independent undervoltage lockouts: BSTUV triggers at 4.2 V (rising) and disables only the affected high-side output (GHx), while GVDDUV triggers at 4.6 V (rising) and disables all gate outputs. Recovery is automatic but requires detection of a low-to-high PWM edge on the corresponding INHx pin (for BSTUV) or restoration of GVDD above threshold (for GVDDUV), ensuring safe, controlled re-engagement of motor phases.

Can DRV8300NRGER drive 100-V PVDD systems reliably despite its 125-V BSTx absolute maximum rating?

Yes - the 125-V BSTx absolute maximum rating provides 25-V margin above the 100-V PVDD rail, accommodating worst-case bootstrap voltage overshoot during fast switching and inductive transients. Combined with -22-V SHx tolerance and built-in cross-conduction prevention, DRV8300NRGER maintains robust operation in high-dV/dt motor drive environments such as e-scooter regenerative braking or power tool stall conditions.
