Product details
Overview
DRV8244PQDGQRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive H-bridge driver supporting 4.5–35 V operation, delivering up to 21 A output current, with integrated high-side current sensing (IPROPI analog output), configurable slew rate, spread-spectrum clocking, and comprehensive diagnostics for brushed DC motor control in door modules, seat actuators, and BCM systems.
For engineers reviewing the DRV8244PQDGQRQ1 datasheet, DRV8244PQDGQRQ1 pinout, DRV8244PQDGQRQ1 application, or DRV8244PQDGQRQ1 equivalent, key selection criteria include its VQFN-HR (16-pin) package, 47 mΩ total RON, SPI (P) interface with external VDD logic supply, on-state/ off-state load diagnostics, and fault reaction configurability (latched vs. retry).
Technical Context
The DRV8244PQDGQRQ1 implements a monolithic N-channel H-bridge with integrated charge pump, high-side current sense amplifier, and programmable protection circuitry. It supports three bridge configurations: single full-bridge (PWM or PH/EN mode) or two independent half-bridges - all controlled via SPI (P) interface with externally supplied 4.5–5.5 V VDD logic rail.
Its diagnostic architecture includes real-time VM voltage monitoring, overcurrent detection with 3 threshold options and 4 filter time settings, overtemperature shutdown, and bidirectional load diagnostics (open-load and short-circuit detection in both active and inactive states), with fault status reported via nFAULT and detailed logging accessible through SPI registers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4.5 V to 35 V (40 V absolute max); supports wide automotive battery range including cold-crank and load-dump transients. |
| Max Output Current | 21 A continuous; enables direct drive of high-torque 12 V brushed DC motors without external current boosting. |
| Total RON | 47 mΩ (HS + LS); measured in VQFN-HR package, enabling low conduction loss and reduced thermal stress at full load. |
| PWM Frequency Support | Up to 25 kHz with automatic dead-time insertion; ensures clean commutation and minimizes shoot-through risk in motor control loops. |
| Logic Interface | SPI (P) variant with dedicated VDD pin (4.5–5.5 V); prevents brown-out during VM under-voltage transients by decoupling logic supply from motor rail. |
| Current Sensing | Integrated high-side proportional current output (IPROPI); eliminates external shunt resistor and associated PCB area, noise, and power loss. |
| Diagnostic Coverage | On- and off-state open-load/short-circuit detection, VM overvoltage (4 threshold options), and configurable fault reaction per function (retry or latch). |
Pinout & Package
VQFN-HR (16-pin) package, 3 mm × 6 mm body size, thermally enhanced with exposed thermal pad; optimized for high-power density and EMI-sensitive automotive layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| nFAULT | Open-drain fault indicator | Active-low signal reporting aggregated fault status; supports pull-up to controller logic rail for direct interrupt handling. |
| IPROPI | Analog current feedback output | Proportional voltage output (0–5.5 V) scaled to load current; enables closed-loop current regulation without external amplification. |
| nSLEEP | Low-power enable input | Asserting low places device in sleep mode drawing ≤1 µA; wake-up latency <20 µs after valid rising edge. |
| VM | Main motor power supply | High-current input (pins 4, 5, 6); must be bypassed with 0.1 µF ceramic + bulk capacitor; supports ISO 7637 transient compliance with external clamping. |
| OUT1 / OUT2 | H-bridge output terminals | Paired high-current outputs (OUT1: pins 8–9; OUT2: pins 5–6); require parallel routing and symmetric layout to balance current sharing and minimize loop inductance. |
| GND | Power ground reference | Multiple GND pins (7, 10–12, 14–16); must be connected to low-impedance ground plane to ensure stable current sensing and thermal performance. |
| SDI / SDO / SCLK / nSCS | SPI serial interface | Full-duplex 4-wire SPI (3.3 V or 5 V tolerant); SDO uses nSLEEP voltage as VIO reference; supports register read/write for configuration and fault logging. |
| VDD | External logic supply | Dedicated 4.5–5.5 V input for SPI (P) variant; isolates digital core from VM fluctuations, eliminating reset events during battery dips. |
Key Features
| Feature | Design Value |
|---|---|
| Configurable slew rate (8 levels) | Reduces EMI emissions by controlling MOSFET turn-on/off dv/dt; selectable per application noise requirements without hardware change. |
| Spread-spectrum clocking | Modulates internal timing to lower peak radiated emissions; meets CISPR 25 Class 5 requirements without added shielding or filtering components. |
| On-state load diagnostics | Detects open-circuit and short-to-battery/ground faults while motor is energized - critical for safety-critical actuator validation in ASIL-B systems. |
| Individual fault reaction configuration | Per-function latched or retry behavior (e.g., OCP retry, OT shutdown latch); enables fine-grained fault management aligned with system-level safety goals. |
| VM overvoltage monitoring (4 thresholds) | Triggers fault before damage occurs during load-dump events; configurable threshold allows tuning to vehicle-specific ISO 16750-2 profiles. |

FAQ
What is the package type and pin count of the DRV8244PQDGQRQ1?
The DRV8244PQDGQRQ1 uses a VQFN-HR (16-pin) package with a 3 mm × 6 mm body size and exposed thermal pad. This thermally enhanced footprint supports high-current operation while minimizing PCB area - critical for compact automotive modules like door ECUs and seat controllers. The pinout includes dedicated SPI lines (SDI, SDO, SCLK, nSCS), dual H-bridge outputs (OUT1/OUT2), and VDD for isolated logic supply.
Does the DRV8244PQDGQRQ1 support both full-bridge and half-bridge configurations?
Yes, the DRV8244PQDGQRQ1 supports configurable operation modes: single full-bridge (using PWM or PH/EN control) or two independent half-bridges (Independent mode). This flexibility allows one DRV8244PQDGQRQ1 to drive either a single reversible motor or two unidirectional actuators - reducing part count in multi-load systems like seat adjusters or BCM auxiliary functions.
How does the integrated current sensing in the DRV8244PQDGQRQ1 eliminate the need for an external shunt resistor?
The DRV8244PQDGQRQ1 integrates a high-side current sense amplifier that delivers a proportional analog voltage (IPROPI) scaled to load current, with typical accuracy matching external shunt-based solutions. This eliminates the power loss, board space, and noise coupling associated with discrete shunts - while maintaining ±5% regulation accuracy across temperature and supply voltage, as verified in TI's electrical characteristics table.
What fault protection features are implemented in the DRV8244PQDGQRQ1?
The DRV8244PQDGQRQ1 includes overcurrent protection (3 threshold options, 4 filter times), overtemperature shutdown, VM overvoltage detection (4 configurable thresholds), and comprehensive load diagnostics - detecting open-load and short-circuit faults both when the H-bridge is active and inactive. Fault reactions (latch or retry) can be configured per function via SPI registers, enabling ASIL-B-aligned safety responses without external supervision.
Is the DRV8244PQDGQRQ1 compatible with 3.3 V microcontrollers?
Yes, the DRV8244PQDGQRQ1 supports 3.3 V logic inputs on EN/IN1, PH/IN2, DRVOFF, and nSLEEP pins, and its SPI interface (SDI/SDO/SCLK/nSCS) is 3.3 V/5 V tolerant. For the SPI (P) variant, VDD operates from 4.5–5.5 V, but logic-level translation is unnecessary - simplifying interface design with common automotive MCUs like the S32K144 or TC3xx families.
