Product details
Overview
DRV8714HQRHARQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive 4-channel smart half-bridge gate driver with integrated wide common-mode current sense amplifiers, 4.9V–37V operation, 50µA–62mA adjustable peak gate drive current, and hardware-only (H/W) interface control mode. It drives brushed DC motors in power seat modules and body control units with inline current sensing and cycle-by-cycle VDS fault response.
For engineers reviewing the DRV8714HQRHARQ1 datasheet, DRV8714HQRHARQ1 pinout, DRV8714HQRHARQ1 application, or DRV8714HQRHARQ1 equivalent, this page delivers verified package mapping (6mm × 6mm VQFN-40), confirmed H/W interface limitations, validated 4-channel gate drive architecture, and real-world diagnostic behavior including fixed 8µs VDS blanking time and nFLT open-drain fault reporting.
Technical Context
The DRV8714HQRHARQ1 implements a hardware-configured multi-stage gate drive architecture with adaptive propagation delay control and slew rate adjustment to minimize EMI while preventing shoot-through via integrated dead-time handshaking. Its tripler charge pump enables 100% PWM duty cycle operation across the full 4.9V–37V supply range.
Two independent wide common-mode shunt amplifiers support inline, high-side, or low-side current sensing with four selectable gain settings (10/20/40/80 V/V) and analog-programmable thresholds for VDS (6-level) and amplifier gain (4-level). Protection includes MOSFET VDS overcurrent monitoring, VGS gate fault detection, offline open-load diagnostics, thermal warning/shutdown, and a window watchdog timer.

Equivalent & Alternatives
The following parts are listed as comparable options for similar multi-channel gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRV8714SQRHARQ1 | SPI interface instead of H/W; adds register-based configuration, 16-level IDRIVE/VDS, programmable blanking/deglitch, watchdog, and offline diagnostics | Required when firmware-controlled diagnostics, dynamic parameter tuning, or multi-device daisy-chaining is needed | Select DRV8714SQRHARQ1 if SPI configurability and enhanced diagnostics outweigh pin count and layout simplicity benefits of DRV8714HQRHARQ1 |
| DRV8305PAPR | 3-phase BLDC gate driver with integrated current sense amps; no H/W mode-SPI-only; lower channel count (3 half-bridges) | Targeted at brushless motor control (e.g., HVAC blowers), not brushed DC; lacks dedicated brake pin and offline open-load test | Choose DRV8305PAPR only for 3-phase BLDC applications requiring integrated FET drivers and current sensing-not a functional replacement for DRV8714HQRHARQ1's 4-channel brushed DC use case |
Compared with DRV8714SQRHARQ1, the DRV8714HQRHARQ1 trades configurability for deterministic timing and reduced MCU resource usage; compared with DRV8305PAPR, it provides higher channel count, brushed DC optimization, and hardware-only control essential for cost-sensitive body electronics.

FAQ
What interface options does the DRV8714HQRHARQ1 support?
The DRV8714HQRHARQ1 supports hardware-only (H/W) interface mode exclusively-no SPI capability. Configuration is performed via analog pins: IDRIVE sets gate current (6 levels), MODE selects PWM input mode (4 levels), GAIN configures amplifier gain (4 levels), and VDS defines overvoltage threshold (6 levels). This eliminates MCU GPIO overhead and simplifies firmware but removes runtime reconfiguration.
Does the DRV8714HQRHARQ1 include current sensing capability?
Yes, the DRV8714HQRHARQ1 integrates two wide common-mode shunt amplifiers (SP1/SN1 and SP2/SN2) supporting inline, high-side, or low-side current sensing. Gain is selectable at 10/20/40/80 V/V via the GAIN pin. Outputs SO1 and SO2 deliver amplified analog signals referenced to DVDD, enabling real-time motor current monitoring without external op-amps.
What protection features are implemented in the DRV8714HQRHARQ1?
The DRV8714HQRHARQ1 includes MOSFET VDS overcurrent monitoring with fixed 4µs deglitch and 8µs blanking, VGS gate fault detection, thermal warning/shutdown, supply voltage monitors (PVDD, DVDD, VCP), offline open-load and short-circuit diagnostics, and a window watchdog timer. Faults assert open-drain nFLT, and DRVOFF provides hardware-driven driver disable.
What package type and dimensions does the DRV8714HQRHARQ1 use?
The DRV8714HQRHARQ1 uses the VQFN-40 (RHA) package: 6.00mm × 6.00mm body size, 0.4mm pitch, with wettable flanks. The exposed thermal pad improves heat dissipation and enables AOI-compatible solder joint inspection-critical for automotive manufacturing traceability and reliability validation.
How does the DRV8714HQRHARQ1 handle motor braking during sleep mode?
The DRV8714HQRHARQ1 supports powered-off braking via the BRAKE pin: asserting logic high enables low-side gate drivers while the device is in nSLEEP mode, allowing controlled motor shorting for rapid deceleration. This feature operates independently of high-side drivers and requires no SPI communication-fully compatible with its hardware-only interface architecture.
