Product details
Overview
DRV8143PQDGQRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive half-bridge driver with integrated high-side current sense, configurable current regulation, 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 features spread spectrum clocking for EMI reduction-used in body control modules and fuel pumps.
For engineers reviewing the DRV8143PQDGQRQ1 datasheet, DRV8143PQDGQRQ1 pinout, DRV8143PQDGQRQ1 application, or DRV8143PQDGQRQ1 equivalent, this page provides verified technical context, validated pin functions for the HVSSOP-28 SPI(P) variant, confirmed RON (49 mΩ), thermal metrics, fault reaction configurability, and real-world automotive use cases requiring functional safety support.
Technical Context
The DRV8143PQDGQRQ1 implements a monolithic N-channel half-bridge with integrated charge pump regulator, high-side current sensing, and proportional analog current feedback on IPROPI. Its SPI(P) interface uses an external 4.5–5.5 V logic supply (VDD) to prevent brownout during VM transients.
It supports six programmable slew rate levels, four overvoltage thresholds on VM, three OCP trip levels with four filter time options, and individual fault reaction configuration (latched or retry per fault type). Diagnostics include on-state and off-state load detection, VM/VCP monitoring, and overtemperature protection with nFAULT indication.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4.5 V to 35 V - supports 12 V and 24 V automotive battery systems with 40 V absolute max rating |
| Max Output Current | 20 A - continuous drive capability for brushed DC motors and solenoids in BCM and seat modules |
| Total RON (HS + LS) | 49 mΩ - measured in HVSSOP package at 25°C, enabling low conduction loss and thermal efficiency |
| PWM Frequency Support | Up to 125 kHz - enables high-resolution motor control with automatic dead time insertion |
| Sleep Current | 1 µA typical at 25°C - meets ultra-low quiescent power requirements for always-on automotive domains |
| Logic Supply | VDD = 4.5–5.5 V - externally supplied for SPI(P) variant, decoupling logic stability from VM rail transients |
| Diagnostic Coverage | On-state & off-state open-load/short-circuit detection - reduces need for external sensing components in safety-critical paths |
Pinout & Package
HVSSOP-28 package (3 mm × 7.3 mm) with exposed thermal pad; designed for high-current routing via multiple parallel VM, OUT, and GND pins (6 each) to sustain 20 A operation with low PCB trace resistance and thermal impedance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–3, 27–28 | Configuration & I/O | SR (slew rate), DIAG (load type), SDI/SCLK/nSCS/SDO (SPI interface), ITRIP (current limit setting) |
| 4–5, 21–23 | Power Input | VM (motor supply) - 6 pins combined to handle high current and reduce voltage drop |
| 6–11, 18–20 | Power Output | OUT (half-bridge output) - 6 pins paralleled for 20 A drive and thermal distribution |
| 12–17 | Ground Return | GND - 6 dedicated pins for low-impedance return path and EMI suppression |
| 24 | Control Input | nSLEEP - active-low entry into ultra-low-power sleep mode (1 µA) |
| 25 | Analog Feedback | IPROPI - proportional current output (0–5.5 V) eliminating need for external shunt resistor |
| 26 | Fault Indicator | nFAULT - open-drain fault flag supporting system-level error handling and ASIL-B diagnostics |
Key Features
| Feature | Design Value |
|---|---|
| Integrated High-Side Current Sense | Eliminates external shunt resistor and associated layout complexity while maintaining ±5% current measurement accuracy |
| Configurable Slew Rate (6 levels) | Reduces EMI emissions by controlling edge rates without sacrificing switching speed in noise-sensitive automotive cabins |
| SPI(P) Interface with External VDD | Prevents device reset during VM under-voltage transients (e.g., cranking), ensuring robust communication in 12 V systems |
| On-State Load Diagnostics | Detects open-circuit and short-to-battery faults while driving - critical for ASIL-B-compliant valve and pump control |
| Programmable Fault Reaction | Per-fault latched or retry behavior enables tailored safety responses (e.g., latch for overtemperature, retry for transient overcurrent) |
| Spread Spectrum Clocking | Modulates internal clock frequency to lower peak EMI amplitude - simplifies EMC compliance testing for CISPR 25 Class 5 |

Equivalent & Alternatives
The following parts are listed as comparable options for similar half-bridge driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRV8143SQDGQRQ1 | VQFN-HR (14) package; internally generated logic supply (no VDD pin); 42 mΩ RON; no nSLEEP pin | Better thermal performance (RθJA = 48.4°C/W vs 31.0°C/W) but lacks external logic supply resilience during VM transients | Select when board space is constrained and VM rail is stable; avoid in cranking-sensitive 12 V systems |
| DRV8144SQDGQRQ1 | VQFN-HR (16) package; 23.6 mΩ RON; 30 A rating; same SPI(S) interface and pinout family compatibility | Higher current capability and lower conduction loss, but larger footprint and higher cost per unit | Select when upgrading from 20 A to 30 A load requirements without changing controller firmware or PCB layout |
Compared with DRV8143PQDGQRQ1, the DRV8143SQDGQRQ1 trades external VDD resilience for smaller size and lower RON, while the DRV8144SQDGQRQ1 offers scalable current capacity within the same SPI(S) interface family-enabling migration paths without full system redesign.

FAQ
What is the package type and pin count for DRV8143PQDGQRQ1?
DRV8143PQDGQRQ1 uses the HVSSOP-28 package (3 mm × 7.3 mm) with 28 leads and an exposed thermal pad. This variant belongs to the SPI(P) family, featuring dedicated VDD, SDI, SDO, SCLK, and nSCS pins for serial configuration and diagnostics-distinct from the HW(H) and SPI(S) variants.
Does DRV8143PQDGQRQ1 support both 3.3 V and 5 V logic inputs?
DRV8143PQDGQRQ1 supports 3.3 V and 5 V logic inputs on its IN, DRVOFF, and nSLEEP pins, with VIH thresholds of 1.5 V and VIL thresholds of 0.7 V. Its SPI(P) interface requires a 4.5–5.5 V VDD supply, making it compatible with standard 5 V microcontroller I/O while maintaining noise margin for 3.3 V systems via level-shifting.
How does the integrated current sense in DRV8143PQDGQRQ1 eliminate the need for a shunt resistor?
DRV8143PQDGQRQ1 integrates high-side current sensing with proportional analog output on the IPROPI pin (0–5.5 V range), calibrated to reflect load current without external components. This eliminates PCB area, power loss, and thermal drift associated with shunt resistors-while maintaining ±5% accuracy across temperature and load conditions.
What fault conditions does DRV8143PQDGQRQ1 detect and how are they reported?
DRV8143PQDGQRQ1 detects open-load, short-to-battery, short-to-ground, overcurrent, overtemperature, VM undervoltage/overvoltage, and VCP faults. All are reported via the open-drain nFAULT pin; SPI(P) variants also provide detailed register-based fault logging-including individual fault latching/retry configuration and diagnostic status flags accessible via SDO.
Is DRV8143PQDGQRQ1 qualified for automotive safety-critical systems?
Yes, DRV8143PQDGQRQ1 is AEC-Q100 Grade 1 qualified (–40°C to +125°C) and functional safety-capable, with documentation available to support ISO 26262 ASIL-B system development. Its diagnostic features-including on-state load detection, redundant fault reporting, and configurable fault reactions-enable integration into safety-managed architectures.
