Product details
Overview
DRV3245CQPHPRQ1 from Texas Instruments is an AEC-Q100 Grade 1 (–40°C to +125°C) automotive 3-phase gate driver IC with integrated high-precision current-shunt amplifiers, 4.5–45 V operation, programmable 1-A peak gate drive, and charge-pump support for 100% duty cycle-designed for electrical power steering (EPS) and brake assist systems.
For engineers reviewing the DRV3245CQPHPRQ1 datasheet, DRV3245CQPHPRQ1 pinout, DRV3245CQPHPRQ1 application, or DRV3245CQPHPRQ1 equivalent, this page delivers verified functional safety features (ASIL D-capable), SPI-configurable protection, real-time gate-source voltage monitoring, and thermal-enhanced HTQFP packaging-critical for ISO 26262-compliant motor control designs.
Technical Context
The DRV3245CQPHPRQ1 implements three independent half-bridge drivers with charge-pump-based high-side gate drive enabling continuous conduction during cold-crank conditions. It integrates three low-drift offset high-precision current-shunt amplifiers and three-phase comparators, all configurable and status-reportable via SPI interface.
Its protection architecture includes MOSFET VDS overcurrent monitors, programmable dead-time control, shoot-through prevention logic, analog built-in self-test, clock monitor, and SPI CRC-each block supports diagnostic instantiation and reporting to meet ASIL D systematic capability requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Voltage | 4.5 V to 45 V - supports full automotive battery range including cold-crank (≤6 V) and load-dump transients. |
| Peak Gate Drive Current | Up to 1 A - enables fast switching of high-Qg N-channel MOSFETs in high-power EPS inverters. |
| Current Sensing | 3× high-precision shunt amplifiers - provides low-offset, low-drift phase current measurement for FOC control. |
| Digital Interface | 3.3-V/5-V compatible SPI - allows configuration, fault reporting, and real-time status readback without level-shifting. |
| Control Modes | 3-PWM or 6-PWM input up to 20 kHz - supports both trapezoidal and field-oriented control topologies. |
| Thermal Package | 48-pin HTQFP (PHP), 7.0 mm × 7.0 mm - PowerPAD-enhanced thermal performance for >3 W dissipation in compact EPS modules. |
| Functional Safety | ISO 26262 ASIL D systematic capability - includes diagnostics coverage for gate drive, sensing, regulators, and clock domains. |
Pinout & Package
DRV3245CQPHPRQ1 uses a thermally enhanced 48-pin HTQFP (PHP) package with exposed PowerPAD for PCB-level heat dissipation. Pin 1 orientation follows Q2 quadrant per tape-and-reel specification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Primary supply input | 4.5–45 V input powering internal regulators and gate drivers; requires local bulk and ceramic decoupling. |
| VDDIO | Digital I/O supply | 3.3-V or 5-V supply for SPI, PWM, and fault pins; independent of VDD for robust interface operation. |
| HINx / LINx (x=1–3) | PWM input terminals | Accept 3-PWM or 6-PWM logic signals; internally conditioned for noise immunity and shoot-through prevention. |
| HOx / LOx (x=1–3) | Gate drive outputs | High- and low-side N-MOS gate drivers with 1-A peak sourcing/sinking; HOx driven by integrated charge pump. |
| CSA_INx (x=1–3) | Current sense amplifier inputs | Differential inputs for shunt resistors; C-device variant uses low-drift amplifiers optimized for <±50 µV offset. |
| nFAULT | Open-drain fault indicator | Asserts low on overtemperature, VDS overcurrent, or SPI CRC error; supports system-level fail-safe shutdown. |
| SCLK / SDI / SDO / nCS | SPI interface pins | Full-duplex SPI with CRC and register lock for safe reconfiguration; supports daisy-chaining in multi-inverter systems. |
Key Features
| Feature | Design Value |
|---|---|
| Charge-pump high-side drive | Enables true 100% duty cycle operation down to 4.5 V supply-critical for maintaining torque during automotive cold-crank. |
| Integrated current sensing | Three matched, low-drift shunt amplifiers eliminate external op-amps and reduce BOM count by ≥4 components per phase. |
| Programmable dead-time | Configurable via SPI (10–500 ns steps) to prevent shoot-through across varying MOSFET gate charge and temperature conditions. |
| Real-time gate monitoring | Continuous VGS monitoring per channel detects gate oxide degradation or open-circuit faults before catastrophic failure. |
| ASIL D-ready diagnostics | On-chip clock monitor, analog BIST, regulator supervision, and SPI CRC provide ≥90% diagnostic coverage per ISO 26262 Annex D. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 3-phase gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRV3245AQPHPRQ1 | Uses standard (non-high-precision) current-shunt amplifiers with higher offset drift (±150 µV vs. ±50 µV). | Suitable for cost-sensitive EPS variants where torque ripple <5% is acceptable; not recommended for high-fidelity brake assist. | Select when BOM cost reduction outweighs need for ultra-low current-sense error in safety-critical torque loops. |
| DRV3245SQPHPRQ1 | Rated for extended junction temperature (–40°C to +150°C); same C-device sensing but no phase comparators. | Targeted at under-hood transmission control units requiring higher ambient tolerance; lacks real-time comparator status via digital pins. | Choose for high-temperature environments where phase comparator output is handled externally or omitted entirely. |
Compared with DRV3245AQPHPRQ1 and DRV3245SQPHPRQ1, the DRV3245CQPHPRQ1 uniquely combines low-drift current sensing, integrated phase comparators with SPI status, and ASIL D diagnostic coverage-making it the only variant qualified for high-integrity brake assist and next-generation EPS with torque ripple <2%.

FAQ
What is the maximum PWM frequency supported by the DRV3245CQPHPRQ1?
The DRV3245CQPHPRQ1 supports input PWM frequencies up to 20 kHz in both 3-PWM and 6-PWM modes. This enables high-resolution field-oriented control (FOC) for low-acoustic-noise EPS and brake assist applications while maintaining sufficient gate drive slew rate for 1-A peak current into typical N-MOS gate capacitances.
Does the DRV3245CQPHPRQ1 include built-in protection against MOSFET shoot-through?
Yes, the DRV3245CQPHPRQ1 implements hardware-level shoot-through prevention logic between each HIN/LIN pair, combined with programmable dead-time control via SPI. This dual-layer protection ensures robustness against timing skew and logic errors, meeting ASIL D requirements for safety-critical motor drives.
How does the current-shunt amplifier performance differ in the DRV3245CQPHPRQ1 versus other DRV3245Q-Q1 variants?
The DRV3245CQPHPRQ1 uses low-drift offset high-precision current-shunt amplifiers with ±50 µV max input offset voltage and <0.5 µV/°C drift-significantly tighter than the ±150 µV spec of the A-device and the uncharacterized drift of the S-device-enabling accurate torque estimation in high-fidelity EPS systems.
Is the DRV3245CQPHPRQ1 pin-compatible with other members of the DRV3245Q-Q1 family?
Yes, all DRV3245Q-Q1 variants-including DRV3245CQPHPRQ1, DRV3245AQPHPRQ1, DRV3245BQPHPRQ1, and DRV3245SQPHPRQ1-share identical 48-pin HTQFP (PHP) packaging, pinout, and footprint. This enables hardware reuse across platform variants while differing only in internal analog performance and feature enablement.
What functional safety documentation is available for the DRV3245CQPHPRQ1?
Texas Instruments provides a full ISO 26262 functional safety package for the DRV3245CQPHPRQ1, including FMEDA reports, safety manual, diagnostic coverage analysis, and ASIL D systematic capability evidence-available under NDA to qualified automotive customers designing to ASIL D requirements.
