Product details
Overview
DRV8144ASQRYJRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive half-bridge driver with integrated high-side current sensing, configurable slew rate, spread-spectrum clocking, and comprehensive diagnostics. It delivers 30A peak output current, operates from 4.5V to 35V, supports PWM up to 125kHz with automatic dead time, and enables precise load current monitoring via proportional IPROPI analog output - used in body control modules for seat actuation and wiper motor control.
For engineers reviewing the DRV8144ASQRYJRQ1 datasheet, DRV8144ASQRYJRQ1 pinout, DRV8144ASQRYJRQ1 application, or DRV8144ASQRYJRQ1 equivalent, key selection criteria include its VQFN-HR (16) package, SPI(S) interface variant, 23.6mΩ total RON, functional safety documentation support, and diagnostic coverage for open-load and short-circuit detection in both on- and off-states.
Technical Context
The DRV8144ASQRYJRQ1 implements a monolithic N-channel half-bridge with integrated charge pump regulator and high-side current sense amplifier. Its architecture supports dual operation modes: hardware-configured (HW-H) and SPI-configurable (SPI-S), with this part being the SPI(S) variant - meaning logic supply is internally derived from VM, eliminating need for external VDD.
It integrates voltage monitoring (VM, VCP), thermal shutdown (155–185°C), overcurrent protection with programmable thresholds and deglitch times, and configurable fault reaction (latched or retry). Load diagnostics include off-state open/short detection and SPI-enabled on-state diagnostics for high-side loads.
Key Specifications

Pinout & Package
VQFN-HR (16-pin) package, 3 mm × 6 mm body size, wettable flank design for automated optical inspection (AOI) and enhanced solder joint reliability in automotive reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| OUT (pins 5,6,8,9) | Half-bridge output terminals | Four paralleled pins deliver 30 A; must be routed together to minimize inductance imbalance |
| GND (pins 7,13,14,15) | Power and signal ground | Multiple GND pins reduce impedance and improve EMI performance; connect to solid ground plane |
| VCP | Charge pump storage node | Connects to 1 µF/6.3 V capacitor between VCP and VM; enables high-side gate drive above VM |
| DRVOFF | Hi-Z control input | Drives bridge into high-impedance state (coast mode); compatible with 3.3 V / 5 V logic |
| IN | Bridge enable input | Direct control of half-bridge switching; internal pull-down ensures safe default state |

Equivalent & Alternatives
The following parts are listed as comparable options for similar half-bridge driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRV8144HQRYJRQ1 | HW(H) variant - pin-strapped configuration only; no SPI interface; fixed slew rate (6 levels); no on-state diagnostics | Limited configurability; suitable for cost-sensitive, fixed-function designs without need for runtime reconfiguration or detailed fault logging | Select when SPI overhead is unnecessary and board space allows simpler routing without SDO/SDI/SCLK/nSCS traces |
| DRV8145ASQRYJRQ1 | Lower RON (16 mΩ), higher IOUT (46 A), larger VQFN-HR (3.5 mm × 5.5 mm); same SPI(S) interface and feature set | Higher power delivery capability; requires updated thermal layout and potentially revised current-sense calibration due to different AIPROPI scaling | Select when >30 A peak current or lower conduction loss is required; verify PCB footprint compatibility and thermal margin |
Compared with DRV8144HQRYJRQ1, the DRV8144ASQRYJRQ1 provides greater flexibility via SPI configuration, on-state diagnostics, and finer slew-rate control - essential for adaptive motor control. Compared with DRV8145ASQRYJRQ1, it offers identical functionality at lower current rating and smaller footprint, making it optimal for space-constrained 30 A applications.

FAQ
What is the package type and pin count of the DRV8144ASQRYJRQ1?
The DRV8144ASQRYJRQ1 uses a VQFN-HR (16-pin) package with a 3 mm × 6 mm body size and wettable flanks. It features 16 terminals including four paralleled OUT pins, four GND pins, and dedicated SPI signals (nSCS, SCLK, SDI, SDO), all optimized for automotive reflow and AOI inspection.
Does the DRV8144ASQRYJRQ1 support both 3.3 V and 5 V logic inputs?
Yes, the DRV8144ASQRYJRQ1 supports 3.3 V and 5 V logic inputs on IN, nSLEEP, DRVOFF, and nFAULT pins, with VIH thresholds of 1.5 V and VIL thresholds of 0.7 V. Its SPI interface (SDI, SDO, SCLK, nSCS) also operates within 0 V to VnSLEEP + 0.5 V, ensuring compatibility with common automotive microcontroller I/O voltages.
How does the integrated current sense in the DRV8144ASQRYJRQ1 eliminate the need for an external shunt resistor?
The DRV8144ASQRYJRQ1 integrates a high-side current sense amplifier with a proportional analog output on the IPROPI pin. With a nominal scaling factor of 4630 A/A and ±5% accuracy above 2.4 A, it delivers a voltage directly proportional to load current - removing the need for external shunt resistors, associated Kelvin traces, and amplification circuitry while maintaining measurement fidelity.

The DRV8144ASQRYJRQ1 provides off-state diagnostics detecting open loads (>10 kΩ for high-side, >2 kΩ for low-side) and shorts (<1 kΩ to VM or GND). In SPI(S) mode, it adds on-state diagnostics using internal sink current (0.25–18 mA) during dead time - enabling real-time fault detection while the motor is actively driven, critical for functional safety compliance.
Is the DRV8144ASQRYJRQ1 qualified for automotive use and what temperature grade does it support?
Yes, the DRV8144ASQRYJRQ1 is AEC-Q100 qualified for automotive applications with Temperature Grade 1 (–40°C to +125°C ambient operating range).
