Product details
Overview
DRV8301QDCARQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive three-phase gate driver IC for brushless DC and PMSM motor control. It integrates three half-bridge drivers (each supporting 2.3-A sink / 1.7-A source peak gate current), dual bidirectional current shunt amplifiers with programmable gain (10× to 80×), and a 1.5-A adjustable-output buck converter - all operating from a single 6–60 V supply. It enables compact, high-reliability motor drive stages in automotive water/oil/fuel pumps.
For engineers reviewing the DRV8301QDCARQ1 datasheet, DRV8301QDCARQ1 pinout, DRV8301QDCARQ1 application, or DRV8301QDCARQ1 equivalent, key selection considerations include bootstrap-based 100% duty cycle support, SPI-configurable dead time and overcurrent protection, VDS-based MOSFET fault detection, and integrated power for MCU and analog circuitry - critical for automotive motor control BOM reduction and functional safety compliance.
Technical Context
The DRV8301QDCARQ1 implements independent high-side/low-side PWM control across three half-bridges using bootstrap gate drivers with trickle-charge circuitry, enabling continuous conduction mode operation. Its automatic hand-shaking logic prevents shoot-through by synchronizing GH_x and GL_x transitions with precise dead-time insertion (50–500 ns, resistor-programmable).
Overcurrent protection uses real-time VDS sensing on each high-side MOSFET (SH_x to PVDD1) and low-side MOSFET (SL_x to SH_x), with 1.5-µs response time and fault reporting via nFAULT/nOCTW pins and SPI status registers. The dual current shunt amplifiers support ±0.3-V differential input range, 300-ns to 2.4-µs settling time (gain-dependent), and output offset calibration via DC_CAL pin.

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 |
|---|---|---|---|
| DRV8323RSRTVRQ1 | Higher 3.5-A peak gate drive; integrated 3.3-V LDO instead of buck; no VDS sensing; SPI-only communication | Lacks VDS-based OCP and buck converter - requires external 3.3-V supply and discrete overcurrent detection | Preferred when higher gate current is needed and system already provides regulated 3.3-V rail |
| MP6532GQ-Z | Non-automotive grade; 60-V max; no integrated current amps or buck; supports 3.3/5-V logic; smaller QFN-40 package | Not AEC-Q100 qualified; lacks diagnostic features and automotive thermal robustness | Suitable for cost-sensitive industrial BLDC drives where automotive qualification is unnecessary |
Compared with DRV8301QDCARQ1, DRV8323RSRTVRQ1 trades VDS sensing and buck integration for higher drive strength and simpler power architecture, while MP6532GQ-Z offers compact packaging and lower cost at the expense of automotive qualification and embedded diagnostics.

FAQ
What is the maximum operating voltage for DRV8301QDCARQ1?
The DRV8301QDCARQ1 supports a recommended operating supply voltage range of 6 V to 60 V on PVDD1 and PVDD2 rails. Absolute maximum rating is 65 V for transient conditions. This wide input range accommodates 12 V, 24 V, and 48 V automotive battery systems including load dump events, making DRV8301QDCARQ1 suitable for direct connection to vehicle battery without external pre-regulation.
Does DRV8301QDCARQ1 support 100% duty cycle operation?
Yes, DRV8301QDCARQ1 supports 100% duty cycle operation using its integrated bootstrap gate drivers with trickle-charge circuitry. This eliminates the need for an external high-side floating supply or dedicated charge pump IC. The trickle-charge feature maintains bootstrap capacitor voltage during sustained high-side conduction, ensuring reliable gate drive for applications like electric turbochargers requiring continuous boost pressure control.
How does overcurrent protection work in DRV8301QDCARQ1?
DRV8301QDCARQ1 implements VDS-based overcurrent protection by continuously monitoring the drain-source voltage of each external N-MOSFET through dedicated sense pins (SH_x and SL_x). When VDS exceeds programmable thresholds (0.125 V to 2.4 V), the device responds within 1.5 µs by pulling nFAULT low and updating SPI fault registers. This method detects both short-circuit and overload conditions independent of shunt resistor accuracy or placement, enhancing reliability in harsh automotive environments.
Can DRV8301QDCARQ1 power an external microcontroller?
Yes, DRV8301QDCARQ1 integrates a configurable buck converter capable of delivering up to 1.5 A, which can power an external microcontroller. Its output voltage is adjustable via external resistors on the VSENSE pin, and it supplies regulated rails including DVDD (3.3 V), AVDD (6 V), and GVDD (6–7 V) - all derived from the main PVDD input. This eliminates the need for separate DC/DC converters in space-constrained automotive motor modules.
Is DRV8301QDCARQ1 pin-compatible with any newer TI gate drivers?
No, DRV8301QDCARQ1 is not pin-compatible with newer TI gate drivers such as DRV8323RSRTVRQ1 or DRV8353SRTVRQ1. These successors use different pinouts, feature sets (e.g., no VDS sensing in DRV8323), and package types. TI explicitly marks DRV8301QDCARQ1 as "Not Recommended for New Designs" due to architectural limitations, and recommends migration paths based on system requirements rather than mechanical compatibility.
