Product details
Overview
DRV8143HQDGQRQ1 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 DRV8143HQDGQRQ1 datasheet, DRV8143HQDGQRQ1 pinout, DRV8143HQDGQRQ1 application, or DRV8143HQDGQRQ1 equivalent, key selection criteria include its VQFN-HR (14) package, 42 mΩ total RON, low 1 µA sleep current, SPI(S) interface variant, and functional safety documentation support for ASIL-B system integration.
Technical Context
The DRV8143HQDGQRQ1 implements a monolithic N-channel half-bridge with integrated charge pump regulator, high-side current sensing, and proportional analog current feedback on IPROPI. Its protection architecture includes configurable overcurrent thresholds (3 settings), programmable fault reaction (latched or retry), and dual-state load diagnostics (on/off) for open-load and short-circuit detection.
It supports both hardwired (HW) and SPI-based configuration; this specific part is the SPI(S) variant-logic supply derived internally from VM-enabling robust operation during VM transients without external VDD. The device uses BiCMOS power process technology and features eight programmable slew-rate levels and spread-spectrum clocking to reduce EMI emissions.
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 medium-power brushed DC motors and solenoids |
| Total RON | 42 mΩ - sum of high-side and low-side FET on-resistance in VQFN-HR package at 25°C, enabling <1 W conduction loss at 20 A |
| PWM Frequency Support | Up to 125 kHz - enables high-resolution motor speed control with automatic dead-time insertion |
| Sleep Current | 1 µA typical at 25°C - minimizes battery drain in always-on vehicle modules like door latches or seat position memory |
| Diagnostic Coverage | On-state & off-state load diagnostics - detects open-load and short-to-battery/ground faults without requiring external circuitry |
| Interface Type | SPI(S) - serial interface with logic supply internally generated from VM, eliminating need for separate 3.3 V/5 V rail |

Equivalent & Alternatives
The following parts are listed as comparable options for similar half-bridge driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRV8144HQDGQRQ1 | Lower 23.6 mΩ RON, 30 A rating, same VQFN-HR (16) package; no SPI(P) variant available | Better thermal performance for higher-current pumps or longer duty-cycle solenoids; requires updated layout due to 16-pin footprint | Select when >20 A peak load current or lower conduction loss is required; verify pin compatibility and thermal margin. |
| DRV8145HQDGQRQ1 | 16 mΩ RON, 46 A rating, VQFN-HR (16) or HTSSOP (28); supports higher VM transients and extended thermal headroom | Targeted at high-power applications like radiator fan control or heavy-duty fluid pumps where sustained 30+ A is needed | Choose for demanding thermal environments or future-proofing; note larger package and higher cost vs. DRV8143HQDGQRQ1. |
Compared with DRV8144HQDGQRQ1 and DRV8145HQDGQRQ1, the DRV8143HQDGQRQ1 provides optimal balance of size (VQFN-HR 14), cost, and 20 A capability for mid-power automotive actuators-making it ideal for space-constrained door, seat, and BCM designs where full 30+ A headroom is unnecessary.

FAQ
What is the package type and pin count of the DRV8143HQDGQRQ1?
The DRV8143HQDGQRQ1 uses a VQFN-HR (14) package with a 3 mm × 4.5 mm body size and an exposed thermal pad. It has 14 terminals, including dual OUT and GND pins for current sharing and thermal performance. This package is distinct from the HVSSOP (28) variant and supports the SPI(S) interface configuration.
Does the DRV8143HQDGQRQ1 support both 3.3 V and 5 V logic inputs?
Yes, the DRV8143HQDGQRQ1 supports 3.3 V and 5 V logic inputs on control pins including IN, DRVOFF, and nSLEEP. Input thresholds are specified down to 0.7 V (VIL) and up to 1.55 V (VIH), ensuring reliable interfacing with common microcontrollers and ASICs across automotive voltage domains.
How does the integrated current sense work in the DRV8143HQDGQRQ1?
The DRV8143HQDGQRQ1 implements high-side current sensing with a proportional analog output on the IPROPI pin. It delivers a voltage linearly scaled to load current (e.g., 1 V/A typical), eliminating the need for external shunt resistors and associated signal conditioning. This feature is active during both on-state and diagnostic modes.
What protection features does the DRV8143HQDGQRQ1 provide?
The DRV8143HQDGQRQ1 includes overcurrent protection (with 3 configurable trip thresholds), overtemperature shutdown, VM and VCP undervoltage monitoring, and comprehensive load diagnostics (open-load and short-circuit detection in both on/off states). Fault reactions can be set to latched or auto-retry via configuration.
Is the DRV8143HQDGQRQ1 pin-compatible with other devices in the DRV814x-Q1 family?
No, the DRV8143HQDGQRQ1 is not pin-compatible with DRV8144HQDGQRQ1 or DRV8145HQDGQRQ1. While all share functional similarity, DRV8143HQDGQRQ1 uses VQFN-HR (14), whereas DRV8144/8145 use VQFN-HR (16) or HTSSOP (28). Pin count, layout, and register mapping differ-requiring board redesign for substitution.
