Product details
Overview
DRV2511QDAPRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive haptic driver IC for solenoid and voice-coil actuators, featuring a full H-bridge output stage delivering 8-A peak current, 4.5 V to 18 V operating supply range, integrated short-circuit/over-temperature/over-voltage protection, and analog differential input with programmable gain (20–36 dB). It enables high-fidelity tactile feedback in infotainment and steering-wheel interfaces.
For engineers reviewing the DRV2511QDAPRQ1 datasheet, DRV2511QDAPRQ1 pinout, DRV2511QDAPRQ1 application, or DRV2511QDAPRQ1 equivalent, key selection criteria include its 8-A peak drive capability, HTSSOP-32 thermal performance (RθJA = 32.4°C/W), BD modulation scheme for low EMI, fault reporting via open-drain INTZ, and automotive-grade reliability across –40°C to 125°C ambient.
Technical Context
The DRV2511QDAPRQ1 implements a BD (Buck-Derived) PWM modulation architecture that delivers differential output voltage with minimal ripple current, enabling precise control of inductive loads while reducing I²R losses. Its gate drivers support bootstrap operation for both high-side (BSTP) and low-side (BSTN) outputs, with dedicated 7-V internal regulator (REG) for gate biasing.
Functional modes include active (full waveform reproduction), standby (low-latency wake-up with 11-mA quiescent current), and shutdown (35-µA quiescent current). Fault detection-over-current (13-A trip), over-temperature (150°C latch), over-voltage (28-V trip), and under-voltage (4.1-V lockout)-is reported via the INTZ pin, supporting automatic recovery when INTZ is tied to EN.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Output Current | 8 A - Enables strong haptic actuation for solenoids ≥1.6 Ω and voice coils without external amplification. |
| Supply Voltage Range | 4.5 V to 18 V - Compatible with automotive battery rails including cold-crank (4.5 V) and load-dump (18 V) conditions. |
| Gain Range | 20 dB to 36 dB - Configurable via external R1/R2 resistors to match input signal amplitude and load sensitivity. |
| Switching Frequency | 376 kHz to 1278 kHz - Selectable via FS2/FS1/FS0 pins to optimize EMI, efficiency, and acoustic noise. |
| RDS(on) | 60 mΩ - Low conduction loss ensures >90% efficiency at 8-A peak, minimizing thermal stress in HTSSOP-32 package. |
| Full-Power Bandwidth | 60 kHz - Supports fast transient haptic waveforms (e.g., ramp click, half-sine) with minimal phase distortion. |
| Thermal Protection | 150°C trip with 15°C hysteresis - Latched fault prevents thermal runaway during sustained high-current events. |
| ESD Rating | HBM ±2000 V, CDM ±500 V - Meets AEC-Q100 requirements for robustness in automotive assembly and field operation. |
Pinout & Package
DRV2511QDAPRQ1 is housed in a thermally enhanced 32-pin HTSSOP (DAP) package (11.00 mm × 6.20 mm) with exposed thermal pad connected to GND for optimal heat dissipation (RθJC(bot) = 1°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN (Pin 2) | Digital Input | Active-low enable controlling full shutdown mode (35 µA IQ) and device reset after latched faults. |
| INTZ (Pin 3) | Digital Output | Open-drain fault indicator - pulled low on over-current, over-temperature, or latch condition; self-clearing for UV/OV. |
| IN+, IN− (Pins 4, 5) | Analog Input | Differential input pair rejecting common-mode noise; supports single-ended biasing via external divider or capacitor. |
| REG (Pins 6, 7) | Power Supply | 7-V internal regulator output - requires 1-µF X7R ceramic decoupling only; not for external loading. |
| GAIN (Pin 8) | Analog Input | Configures pre-amplifier gain (20–36 dB) via external resistor divider; sets input impedance from 9 kΩ to 60 kΩ. |
| STDBY (Pin 12) | Digital Input | Active-high standby control - reduces IQ to 11 mA while preserving fast wake-up for low-latency haptics. |
| FS2/FS1/FS0 (Pins 13–15) | Digital Input | 3-bit selection of oscillator frequency (376–1278 kHz) to balance EMI, efficiency, and audible noise. |
| AVDD (Pin 17) | Power Supply | Analog supply rail - can be tied to PVDD for single-rail operation or isolated for noise-sensitive applications. |
| PVDD (Pins 18, 19, 31, 32) | Power Supply | Main power input (4.5–18 V); multiple pins reduce IR drop and improve current sharing in high-peak applications. |
| BSTP (Pins 26, 30) | Power Supply | Bootstrap capacitor connection for high-side gate drive - requires 220-nF X5R ceramic to OUT+. |
| BSTN (Pins 20, 24) | Power Supply | Bootstrap capacitor connection for low-side gate drive - requires 220-nF X5R ceramic to OUT−. |
| OUT+ (Pins 27, 29) | Amplifier Output | Positive H-bridge output - paralleled pins handle 8-A peak current with minimized trace inductance. |
| OUT− (Pins 21, 23) | Amplifier Output | Negative H-bridge output - paralleled pins ensure symmetrical drive and thermal distribution. |
| GND (Pins 1, 9, 10, 11, 22, 25, 28) | Ground | Multiple ground connections reduce impedance and improve noise immunity; thermal pad must connect to GND plane. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar haptic driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRV2510QDAPRQ1 | 4-A peak output, same package and pinout; lacks BSTN/BSTP pins and dual bootstrap architecture. | Suitable for lower-force haptics (e.g., small solenoids <2 Ω) but cannot drive 8-A loads or support high-efficiency BD modulation. | Select DRV2511QDAPRQ1 when 8-A peak drive, full H-bridge bootstrap control, or 60-kHz bandwidth are required. |
| TPS65987D | USB-C PD controller with integrated haptic driver (2-A max); not AEC-Q100 qualified and lacks fault reporting pins. | Targeted at consumer USB peripherals, not automotive systems requiring ISO 26262-aligned diagnostics or extended temperature operation. | Choose DRV2511QDAPRQ1 for automotive haptics demanding AEC-Q100 Grade 1, latched fault reporting, and 8-A capability. |
Compared with DRV2510QDAPRQ1 and TPS65987D, DRV2511QDAPRQ1 uniquely combines automotive qualification, 8-A peak drive, BD modulation, and comprehensive fault reporting - making it the only option for high-fidelity, safety-aware haptic systems in infotainment and steering-wheel domains.

FAQ
What is the maximum continuous current rating for DRV2511QDAPRQ1?
The DRV2511QDAPRQ1 is rated for 8-A peak output current. Its continuous current capability depends on PCB layout, thermal management, and ambient temperature. With proper copper area on the thermal pad and airflow, DRV2511QDAPRQ1 supports ~3.5-A RMS continuous drive at 25°C ambient. Derating is required above 85°C ambient per the RθJA = 32.4°C/W specification.
How does the BD modulation in DRV2511QDAPRQ1 reduce EMI compared to standard PWM?
The BD modulation in DRV2511QDAPRQ1 minimizes switching current slew rate and ensures OUT+ and OUT− are in-phase at zero differential output, reducing high-frequency harmonics. Combined with optimized gate drive timing and low-parasitic HTSSOP-32 packaging, this cuts radiated emissions by up to 10 dB versus conventional Class-D drivers - critical for automotive EMC compliance.
Can DRV2511QDAPRQ1 operate from a single 12-V supply without external regulators?
Yes. DRV2511QDAPRQ1 supports single-supply operation: connect AVDD to PVDD (12 V), use the internal 7-V REG for gate biasing, and configure GAIN with external resistors. The device draws only 20 mA quiescent current and tolerates 4.5–18 V, making it ideal for direct connection to automotive battery rails without auxiliary regulation.
What happens when an over-temperature fault occurs on DRV2511QDAPRQ1?
When junction temperature exceeds 150°C, DRV2511QDAPRQ1 triggers a latched over-temperature fault: INTZ pulls low, outputs go to high-impedance, and operation halts until EN is cycled. Thermal hysteresis of 15°C ensures stable recovery at ≤135°C. This protects both the IC and connected solenoid/voice-coil from thermal damage.
Is DRV2511QDAPRQ1 pin-compatible with any other TI haptic drivers?
No. DRV2511QDAPRQ1 has a unique 32-pin HTSSOP pinout optimized for dual bootstrap (BSTP/BSTN), differential inputs (IN+/IN−), and fault reporting (INTZ). While DRV2510QDAPRQ1 shares the same package footprint, it omits BSTN, FS2, and several GND pins - making it not pin-compatible. Board redesign is required for substitution.
