Product details
Overview
DRV8143HQRXYRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive half-bridge driver with integrated high-side current sense, configurable slew rate, spread-spectrum clocking, and comprehensive diagnostics. It operates from 4.5 V to 35 V, delivers up to 20 A output current, supports PWM frequencies up to 125 kHz with automatic dead time, and targets brushed DC motor control in body electronics modules.
For engineers reviewing the DRV8143HQRXYRQ1 datasheet, DRV8143HQRXYRQ1 pinout, DRV8143HQRXYRQ1 application, or DRV8143HQRXYRQ1 equivalent, this page provides verified package mapping (VQFN-HR, 14-pin), confirmed HW (H) variant functionality, validated diagnostic coverage (on-state/off-state open-load and short-circuit detection), and real-world EMI mitigation features including programmable slew rate and spread-spectrum clocking.
Technical Context
The DRV8143HQRXYRQ1 implements a monolithic N-channel half-bridge with integrated charge pump regulator and high-side current sensing architecture. It uses BiCMOS high-power process technology to achieve low RON (42 mΩ typical for HS + LS in VQFN-HR package) and robust thermal performance (RθJA = 48.4°C/W).
Its HW (H) interface variant relies on dedicated configuration pins (ITRIP, SR, DIAG) for setting current limit, slew rate, and load type-enabling deterministic, pin-driven operation without SPI overhead. Fault handling includes configurable latched or retry behavior, with voltage monitoring on VM and VCP, overcurrent, and overtemperature protection-all signaled via open-drain nFAULT.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | 4.5 V to 35 V (40 V absolute max); supports 12 V/24 V automotive battery rails with transient tolerance. |
| Max Output Current | 20 A continuous; determined by thermal limits and RON (42 mΩ HS+LS in VQFN-HR) at TJ ≤ 150°C. |
| PWM Frequency | Up to 125 kHz with automatic dead-time insertion; enables precise speed control of brushed DC motors. |
| Current Sense | Integrated high-side sensing with proportional analog output (IPROPI); eliminates external shunt resistor and associated PCB area/power loss. |
| Diagnostic Coverage | Detects open-load and short-circuit faults in both on-state and off-state; reduces need for external monitoring circuitry. |
| Sleep Current | 1 µA typical at 25°C; enables ultra-low quiescent power in always-on vehicle modules like door latches or seat position memory. |
| Logic Compatibility | Supports 3.3 V and 5 V logic inputs; simplifies interface with common microcontrollers and ASICs without level-shifting. |
Pinout & Package
VQFN-HR (14-pin) package, 3 mm × 4.5 mm nominal body size, wettable flank design for automated optical inspection. Thermal pad on underside requires solder connection to PCB ground plane for optimal thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| nFAULT | Open-drain fault indicator | Active-low signal asserted during VM/VCP undervoltage, overcurrent, overtemperature, or load fault; pulled high externally to enable interrupt-driven diagnostics. |
| IPROPI | Analog current feedback output | Proportional to load current (0–5.5 V range); used for closed-loop current regulation or real-time motor health monitoring. |
| nSLEEP | Low-power mode control input | Asserting low places device in sleep state (IVM ≈ 1 µA); wake-up occurs on rising edge with 10 µs tWAKEUP latency. |
| VM | Main motor supply input | Connects to 4.5–35 V battery rail; bypassed with 0.1 µF ceramic + bulk capacitor; powers internal FETs and charge pump. |
| OUT | Half-bridge output node | Two pins (5 & 7) tied together to deliver full 20 A; connects directly to motor terminal or solenoid coil. |
| GND | Power ground reference | Single GND pin (6); must be routed with low-inductance path to minimize noise coupling into sensitive analog circuits. |
| VCP | Charge pump storage node | Requires 1 µF, 6.3 V ceramic capacitor to VM; generates gate drive voltage for high-side N-FET without external bootstrap components. |
| DRVOFF | Hi-Z bridge disable input | High-level assertion forces OUT into high-impedance state; used for freewheeling or emergency shutdown independent of IN logic. |
| IN | Bridge enable/control input | Direct TTL/CMOS-compatible input controlling high-side conduction; internal pull-down ensures safe default OFF state. |
| DIAG | Load type configuration pin | Resistor-programmed selection between high-side and low-side load diagnostics; sets fault interpretation logic. |
| SR | Slew rate configuration pin | 6-level resistor-based setting (0–100 kΩ) adjusts dV/dt on OUT to balance EMI reduction vs. switching loss. |
| ITRIP | Overcurrent threshold pin | Resistor-programmed trip level (6 discrete settings) defines high-side current limit before OCP triggers. |
| NC | No-connect terminal | Pin 14 is unconnected internally; must remain floating or grounded per layout best practices-no routing required. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated high-side current sense | Eliminates external shunt resistor and associated power dissipation, board space, and calibration drift-enabling compact, cost-effective motor control designs. |
| Configurable slew rate (6 levels) | Reduces electromagnetic interference (EMI) emissions by limiting dV/dt on the half-bridge output, easing compliance with CISPR 25 Class 5 requirements. |
| On- and off-state load diagnostics | Identifies open-circuit and short-circuit faults regardless of driver state-critical for functional safety (ISO 26262 ASIL-B capable systems) and predictive maintenance. |
| Spread-spectrum clocking (SSC) | Modulates internal timing to spread radiated energy across frequency band, lowering peak EMI without sacrificing PWM resolution or control fidelity. |
| AEC-Q100 Grade 1 qualification | Validated for –40°C to +125°C ambient operation; ensures reliability in under-hood and cabin-mounted automotive applications including BCM and seat modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar half-bridge driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRV8144HQRGYRQ1 | Lower RON (23.6 mΩ HS+LS), higher IOUT (30 A), VQFN-HR (16-pin), same HW (H) interface. | Better suited for higher-current loads (e.g., larger solenoids or dual-motor drives) where thermal margin is constrained. | Select when >20 A continuous current or lower conduction loss is required; note different pin count and footprint. |
| DRV8143PWRXYRQ1 | SPI(P) variant in HVSSOP-28; external 5 V logic supply (VDD), higher RON (49 mΩ), no nSLEEP pin. | Preferred where advanced diagnostics, register-level fault logging, or immunity to VM brown-out during transients is needed. | Choose for systems requiring SPI configurability and enhanced observability-accept trade-off of larger package and no sleep mode. |
Compared with DRV8143HQRXYRQ1, DRV8144HQRGYRQ1 offers higher current capability in identical VQFN-HR form factor but requires PCB redesign due to 16-pin layout, while DRV8143PWRXYRQ1 trades pin simplicity and sleep functionality for SPI-based diagnostics and brown-out resilience-making it suitable for complex, software-managed motor subsystems.
