Product details
Overview
DRV8714SQPHPRQ1 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 operating range, 50µA–62mA adjustable peak gate drive current, and SPI/HW interface support for brushed DC motor control in body electronics modules.
For engineers reviewing the DRV8714SQPHPRQ1 datasheet, DRV8714SQPHPRQ1 pinout, DRV8714SQPHPRQ1 application, or DRV8714SQPHPRQ1 equivalent, this page delivers verified package mapping (HTQFP-48), confirmed pin functions (e.g., DRVOFF/nFLT, BRAKE, SP1/SN1), real-time protection features (VDS/VGS fault monitoring, thermal shutdown), and validated alternative options for automotive motor drive designs.
Technical Context
The DRV8714SQPHPRQ1 implements a smart multi-stage gate drive architecture with adaptive propagation delay control and adjustable slew rate to suppress EMI while preventing shoot-through via integrated dead-time handshaking. It supports independent half-bridge or H-bridge configurations using four PWM inputs multiplexed with SPI register control.
Its dual wide common-mode shunt amplifiers (10/20/40/80V/V gain) enable inline current sensing during recirculation windows and operate in high-side, low-side, or inline configurations. Protection includes VDS overcurrent, VGS gate fault, offline open-load/short-circuit diagnostics, and a window watchdog timer with nFAULT interrupt reporting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Voltage | 4.9V to 37V (40V abs. max): Supports full automotive battery range including cold-crank and load-dump transients. |
| Gate Drive Current | 50µA to 62mA peak source/sink: Enables fast MOSFET switching across diverse RDS(on) and Qg values. |
| Current Sense Gain | 10, 20, 40, or 80V/V: Configurable amplifier gain allows precise motor current measurement with standard shunt resistors. |
| Interface Options | SPI and hardware (H/W) modes: SPI enables full diagnostics and register configuration; H/W reduces MCU pin count with analog-level mode selection. |
| Protection Features | VDS/VGS fault monitoring, thermal warning/shutdown, offline open-load/short-circuit detection, window watchdog: Enables robust fault recovery without external supervision. |
| AEC-Q100 Grade | Grade 1 (–40°C to +125°C TA): Qualified for under-hood and cabin-mounted automotive applications requiring extended temperature operation. |
Pinout & Package
DRV8714SQPHPRQ1 is packaged in a 48-pin HTQFP (PHP) with 7.00mm × 7.00mm body size and wettable flanks for automated optical inspection. The package integrates a thermal pad for enhanced power dissipation in motor drive applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1/EN1 – IN4/EN4 | Digital control input | Four independent half-bridge enable/control pins supporting EN/PH or EN/EN modes per bridge pair. |
| DRVOFF/nFLT | Multi-function I/O | Configurable as driver disable input or open-drain fault indicator output-reduces system pin count. |
| BRAKE | Digital input | Enables low-side gate drivers during sleep mode for powered-off motor braking without MCU wake-up. |
| SP1/SN1, SP2/SN2 | Analog current sense inputs | Differential inputs for two independent shunt amplifiers-support inline, high-side, or low-side sensing topologies. |
| SO1/SO2 | Analog outputs | Amplified current sense outputs referenced to AREF; require no external op-amp for ADC interfacing. |
| GH1–GH4, GL1–GL4 | Gate driver outputs | Eight dedicated analog outputs driving high-side and low-side MOSFET gates with programmable slew and current. |
| VCP, CP1H/CP1L, CP2H/CP2L | Charge pump network | Supports 100% duty-cycle operation via tripler charge pump; CP nodes require 100nF ceramic capacitors. |
| PVDD, DVDD, GND, AGND, DGND | Power and ground rails | Separated power domains isolate noisy gate drive (PVDD) from logic (DVDD) and analog (AGND) sections. |
Key Features
| Feature | Design Value |
|---|---|
| Smart gate drive architecture | Adaptive propagation delay and adjustable slew rate reduce EMI and prevent shoot-through without external timing components. |
| Dual wide common-mode amplifiers | ±5V input common-mode range with 10–80V/V gain enables accurate inline current sensing during PWM recirculation. |
| Multi-interface flexibility | SPI mode provides full register access and diagnostics; H/W mode uses analog pins (MODE, GAIN, VDS, IDRIVE) for minimal MCU resource usage. |
| Integrated protection suite | VDS overcurrent, VGS gate fault, thermal warning/shutdown, offline diagnostics, and window watchdog eliminate need for discrete fault management circuitry. |
| Low-power braking | BRAKE pin activates low-side drivers in sleep mode-enabling fail-safe mechanical braking without waking the host controller. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 4-channel automotive gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRV8714HQPHPRQ1 | H/W-only interface; fixed VDS threshold (800mV), no SPI register access, no offline diagnostics or watchdog timer. | Limited to simple on/off or speed control where full diagnostics and configurability are unnecessary. | Select when MCU pin count is critical and advanced fault logging is not required-reduces BOM cost and firmware overhead. |
| DRV8305PAPRQ1 | 3-phase BLDC gate driver; no inline current sense amplifiers; only one integrated shunt amp (non-wide common-mode); different PWM mapping. | Designed for brushless motor commutation-not suitable for brushed DC H-bridge topologies requiring independent channel control. | Choose only for 3-phase BLDC applications; incompatible with DRV8714SQPHPRQ1's 4-channel brushed DC architecture and current sensing requirements. |
Compared with DRV8714HQPHPRQ1 and DRV8305PAPRQ1, the DRV8714SQPHPRQ1 uniquely combines SPI configurability, dual wide common-mode amplifiers, and comprehensive offline diagnostics-making it the only option among the three qualified for complex, safety-aware brushed DC motor systems requiring real-time current feedback and fault traceability.

FAQ
What is the maximum operating voltage for the DRV8714SQPHPRQ1?
The DRV8714SQPHPRQ1 supports a recommended operating range of 4.9V to 37V, with an absolute maximum rating of 40V on PVDD. This accommodates automotive battery transients including cold-crank (down to ~4.5V) and load-dump events (up to 37V sustained), ensuring robust operation across all vehicle operating conditions. The device incorporates internal undervoltage and overvoltage monitors on PVDD, DVDD, and VCP rails to trigger fault responses before reaching absolute limits.
Does the DRV8714SQPHPRQ1 support inline current sensing during PWM recirculation?
Yes, the DRV8714SQPHPRQ1 supports continuous inline current sensing during PWM recirculation windows using its dual wide common-mode shunt amplifiers. Each amplifier offers ±5V input common-mode range and selectable gains of 10, 20, 40, or 80V/V-enabling accurate measurement even when the shunt is placed between the H-bridge and motor (high-side of low-side FET). This capability eliminates blind spots in current feedback during freewheeling phases.
How does the BRAKE pin function in the DRV8714SQPHPRQ1?
The BRAKE pin on the DRV8714SQPHPRQ1 enables powered-off motor braking by activating low-side gate drivers while the device is in sleep mode (nSLEEP = low). When BRAKE is asserted high, the IC drives all low-side MOSFETs ON-shorting the motor terminals to dissipate kinetic energy. This feature operates independently of the main control logic and requires no MCU intervention, providing fail-safe mechanical braking during power-down sequences.
What protection features are integrated into the DRV8714SQPHPRQ1?
The DRV8714SQPHPRQ1 integrates multiple hardware-based protections: VDS overcurrent monitoring per MOSFET, VGS gate fault detection, thermal warning and shutdown, supply voltage monitors (PVDD, DVDD, VCP), offline open-load and short-circuit diagnostics, and a window watchdog timer. Faults are reported via the nFAULT pin and can be configured to trigger automatic cycle-by-cycle or latched responses-reducing reliance on software-based safety checks.
Is the DRV8714SQPHPRQ1 pin-compatible with other devices in the DRV871x-Q1 family?
The DRV8714SQPHPRQ1 (HTQFP-48) is not pin-compatible with the DRV8714S-Q1 VQFN-40 or VQFN-56 variants due to differing pin counts and signal assignments. However, it shares functional equivalence with the DRV8714HQPHPRQ1 (same HTQFP-48 package), differing only in interface mode (SPI vs. H/W) and diagnostic depth. Pin mapping must be verified against the specific package drawing-no drop-in replacement is guaranteed across package types.
