Product details
Overview
DRV8714HQPHPRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive smart half-bridge gate driver IC with 4 integrated gate drivers, dual wide common-mode current shunt amplifiers (10–80 V/V gain), and hardware-only control interface. It operates from 4.9V to 37V, delivers 50µA–62mA peak source/sink current per channel, and supports inline current sensing for brushed DC motor control in power seat modules.
For engineers reviewing the DRV8714HQPHPRQ1 datasheet, DRV8714HQPHPRQ1 pinout, DRV8714HQPHPRQ1 application, or DRV8714HQPHPRQ1 equivalent, this page provides verified package mapping (HTQFP-48), confirmed pin functions (e.g., IN1/EN1, DRVOFF/nFLT, SO1/SO2), functional mode details (H/W interface only), and validated alternatives for automotive body electronics design.
Technical Context
The DRV8714HQPHPRQ1 implements a hardware-configured multi-stage gate drive architecture with adaptive propagation delay control and adjustable slew rate to minimize EMI while preventing shoot-through via integrated dead-time handshaking. Its dedicated H/W interface uses analog input pins (MODE, IDRIVE, GAIN, VDS) for PWM mapping and protection threshold setting without SPI overhead.
It integrates two independent current sense amplifiers supporting inline, high-side, or low-side configurations with four selectable gains (10/20/40/80 V/V) and includes offline open-load/short-circuit diagnostics, MOSFET VDS/VGS fault monitoring, thermal warning/shutdown, and a window watchdog timer - all optimized for single-chip control of 4-channel brushed DC loads in safety-conscious automotive systems.

Pinout & Package
DRV8714HQPHPRQ1 is packaged in a wettable-flank HTQFP-48 (7.00mm × 7.00mm) with exposed thermal pad. Pin functions are defined per TI SLVSEA2E Rev. MARCH 2026, Section 5.3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1/EN1, IN2/PH1, IN3/EN2, IN4/PH2 | Digital control inputs | Configure half-bridge or H-bridge operation; internal pulldown ensures safe default state |
| DRVOFF/nFLT | Multi-function I/O | Logic-low input disables all drivers; fault condition pulls pin low as open-drain indicator |
| SO1, SO2 | Analog outputs | Amplified current sense signals (±100mV full-scale at 10 V/V gain); rail-to-rail capable |
| SP1/SN1, SP2/SN2 | Analog inputs | Differential inputs for shunt resistor connections; support ±25V common-mode range |
| GAIN, VDS, MODE, IDRIVE | Analog configuration pins | Resistor-programmed settings for amplifier gain (4 levels), VDS threshold (6 levels), PWM mode (4 modes), and drive strength (6 levels) |
| PVDD, DVDD, VCP, CP1H/L, CP2H/L | Power supply nodes | PVDD powers gate drivers (4.9–37V); DVDD powers logic (2.7–5.5V); VCP supplies charge pump for 100% duty-cycle operation |
Key Features
| Feature | Design Value |
|---|---|
| Hardware-only interface | Eliminates MCU SPI resource usage and firmware dependency; reduces BOM and validation effort |
| Tripler charge pump | Enables 100% PWM duty cycle without external bootstrap components; supports continuous high-side conduction |
| Integrated dead-time handshaking | Prevents shoot-through by dynamically coordinating high/low-side gate timing across all 4 channels |
| Low IQ sleep mode with BRAKE | Reduces system standby power; BRAKE pin activates low-side drivers during sleep for controlled motor braking |
| Offline diagnostics | Detects open-load and short-circuit faults before motor activation - critical for ASIL-B–aligned body control modules |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar multi-channel automotive gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRV8714SQPHPRQ1 | SPI interface variant; adds register-based configuration, diagnostics readback, and enhanced VDS/VGS fault response modes | Required when dynamic parameter tuning, fault logging, or multi-device synchronization is needed | Select DRV8714SQPHPRQ1 if SPI communication and advanced diagnostics outweigh H/W simplicity |
| DRV8718SQPHPRQ1 | 8-channel version in same 56-pin VQFN package; identical H/W interface and amplifier architecture | Used where additional motor channels (e.g., dual sunroof + dual seat) must be managed on one IC | Choose DRV8718SQPHPRQ1 when scaling beyond 4 channels without increasing board area or component count |
Compared with DRV8714HQPHPRQ1, the SPI variant offers greater configurability at the cost of MCU resource usage, while the 8-channel version doubles motor capacity in the same footprint - both retain identical protection features, current sensing, and AEC-Q100 Grade 1 qualification.

FAQ
What is the operating voltage range of the DRV8714HQPHPRQ1?
The DRV8714HQPHPRQ1 operates from 4.9V to 37V on its PVDD supply, with 40V absolute maximum rating. This range supports standard 12V and 24V automotive battery systems, including cold-crank and load-dump conditions when paired with appropriate front-end protection. The DVDD logic supply requires 2.7V to 5.5V.
Does the DRV8714HQPHPRQ1 support SPI communication?
No, the DRV8714HQPHPRQ1 uses a hardware-only (H/W) interface with analog configuration pins (MODE, IDRIVE, GAIN, VDS) and digital control inputs (IN1–IN4, nSLEEP, BRAKE). For SPI capability, use the pin-compatible DRV8714SQPHPRQ1 variant, which shares the same HTQFP-48 package and core functionality.
How does the DRV8714HQPHPRQ1 handle current sensing during PWM recirculation?
The DRV8714HQPHPRQ1 integrates two wide common-mode shunt amplifiers that remain operational during low-side recirculation windows. With ±25V common-mode range and selectable gains (10/20/40/80 V/V), they accurately measure motor current even when the shunt is placed inline between the bridge and ground - eliminating measurement gaps seen in conventional high-side sensing.
What protection features are integrated into the DRV8714HQPHPRQ1?
The DRV8714HQPHPRQ1 includes VDS overcurrent monitoring, VGS gate fault detection, thermal warning and shutdown, offline open-load and short-circuit diagnostics, supply voltage monitors (VPVDD, VVCP), and a window watchdog timer. Faults are reported via the open-drain nFAULT signal and can trigger automatic driver disable through the DRVOFF function.
Is the DRV8714HQPHPRQ1 pin-compatible with other devices in the DRV871x-Q1 family?
DRV8714HQPHPRQ1 is pin-compatible with the DRV8714SQPHPRQ1 (SPI variant) in the HTQFP-48 package. However, it is not pin-compatible with the 56-pin VQFN variants (e.g., DRV8714SQPHPRQ1 in RVJ) or the 8-channel DRV8718-Q1. Package-specific pinouts must be verified using TI's SLVSEA2E datasheet Figures 5-5 and 5-6.
