Product details
Overview
DRV3245BQPHPRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive 3-phase gate driver IC for motor control, featuring 4.5–45 V operation, programmable 1-A peak gate drive current, charge-pump support for 100% duty cycle, and dual current-shunt amplifiers with real-time digital monitoring. It serves as a functional-safety-compliant gate driver unit (GDU) in EPS and brake assist systems.
For engineers reviewing the DRV3245BQPHPRQ1 datasheet, DRV3245BQPHPRQ1 pinout, DRV3245BQPHPRQ1 application, or DRV3245BQPHPRQ1 equivalent, this device delivers ASIL D–capable diagnostics, 3-/6-PWM input support up to 20 kHz, integrated MOSFET protection (shoot-through prevention, VDS overcurrent, real-time VGS monitor), and thermal shutdown - all in a thermally enhanced 48-pin HTQFP package.
Technical Context
The DRV3245BQPHPRQ1 implements three independent half-bridge drivers with high-side/low-side N-channel MOSFET control logic, enabled by an internal charge-pump regulator that sustains gate drive during cold-crank battery conditions. Its integrated dual current-shunt amplifiers feed phase comparators with real-time status output via dedicated digital pins - not SPI - distinguishing it from the A/C/S variants.
Functional safety architecture includes systematic ASIL D capability, SPI CRC, clock monitor, analog built-in self-test, programmable dead-time control, and overtemperature warning/shutdown. Protection features are implemented at both gate-driver and power-stage levels, including MOSFET shoot-through prevention and VDS overcurrent detection per phase.
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 | Programmable up to 1 A - enables fast switching of high-Qg automotive MOSFETs while minimizing Miller plateau time. |
| Current Sensing | 2 integrated current-shunt amplifiers - provides real-time analog sensing for two motor phases with digital comparator outputs. |
| PWM Input Mode | 3-PWM or 6-PWM support up to 20 kHz - compatible with standard MCU-based motor commutation schemes. |
| Digital Interface | 3.3-V and 5-V tolerant logic inputs - eliminates level-shifting requirements in mixed-voltage automotive ECUs. |

| Thermal Rating | −40°C to +125°C ambient (Grade 1) - qualified per AEC-Q100 for under-hood EPS and brake control modules. |
Pinout & Package
DRV3245BQPHPRQ1 is housed in a thermally enhanced 48-pin HTQFP (PHP) package with 7.0 mm × 7.0 mm body size, 0.5 mm pitch, and exposed PowerPAD for PCB-level thermal management. The package complies with JEDEC MS-026 and is rated MSL Level-3 (260°C, 168 hr).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Primary supply input | 4.5–45 V input powering gate drivers, logic, and internal regulators; requires local bulk and ceramic decoupling. |
| VDDIO | Digital I/O supply | 3.3-V or 5-V supply for PWM, SPI, and diagnostic pins; independent of VDD for robust interface operation. |
| HINx / LINx (x=1–3) | PWM input terminals | Three pairs accepting 3-PWM or 6-PWM logic signals; edge-triggered with internal Schmitt triggers and noise filtering. |
| HOx / LOx (x=1–3) | High-side/low-side gate outputs | Direct-drive outputs for external N-channel MOSFET gates; each pair supports independent dead-time insertion. |
| CSA_P / CSA_N (x=1–2) | Current-shunt amplifier inputs | Differential inputs for two shunt resistors; configured for bidirectional current sensing in two motor phases. |
| COMP_OUTx (x=1–3) | Phase comparator digital outputs | Real-time open-drain outputs indicating phase current polarity/comparison result - no SPI dependency. |
| nFAULT | Fault reporting terminal | Active-low, open-drain output signaling overtemperature, VDS overcurrent, shoot-through, or internal regulator fault. |
| PGND / AGND | Power/Analog ground planes | Separate ground pins minimize noise coupling between high-current gate paths and precision analog sensing circuits. |
Key Features
| Feature | Design Value |
|---|---|
| Charge-pump gate driver | Enables 100% high-side duty cycle without external bootstrap components - critical for low-speed, high-torque EPS operation. |
| Dual real-time current monitors | Two integrated shunt amplifiers with dedicated digital comparator outputs eliminate need for external op-amps or ADC polling. |
| Programmable dead-time control | Configurable via SPI to prevent shoot-through across all three half-bridges - adjustable per phase for asymmetrical FET timing. |
| MOSFET VDS overcurrent detection | Per-phase voltage monitoring during switching transitions - detects short-circuit faults before thermal damage occurs. |
| Integrated analog BIST | On-chip self-test verifies amplifier gain, comparator thresholds, and internal reference stability - reduces system-level test coverage burden. |

FAQ
What is the key functional difference between DRV3245BQPHPRQ1 and DRV3245AQPHPRQ1?
The DRV3245BQPHPRQ1 integrates two current-shunt amplifiers with real-time digital comparator outputs on dedicated pins, whereas the DRV3245AQPHPRQ1 provides three current-shunt amplifiers with status reporting exclusively via SPI. Both share identical gate drive capability, protection features, and HTQFP-48 packaging. This makes the B variant optimal for dual-phase sensing with minimal MCU overhead, while the A variant suits full 3-phase SPI-managed monitoring.
Does DRV3245BQPHPRQ1 support 100% duty cycle operation, and how is it achieved?
Yes, DRV3245BQPHPRQ1 supports 100% high-side duty cycle using an integrated charge-pump circuit that maintains gate voltage above threshold even during sustained low-input-voltage conditions such as automotive cold-crank (down to 4.5 V). This eliminates reliance on external bootstrap capacitors and ensures reliable gate drive in EPS and brake assist applications requiring continuous torque output at zero speed.
What protection features are implemented in DRV3245BQPHPRQ1 to ensure safe motor operation?
DRV3245BQPHPRQ1 includes MOSFET shoot-through prevention via hardware-enforced dead-time, per-phase VDS overcurrent monitoring, real-time gate-source voltage (VGS) monitoring, internal regulator fault detection, battery voltage monitoring, clock monitor, analog built-in self-test, and overtemperature warning with thermal shutdown. All protections feed into the nFAULT pin for immediate system-level response.
Can DRV3245BQPHPRQ1 be used with both 3.3-V and 5-V microcontrollers?
Yes, DRV3245BQPHPRQ1 supports both 3.3-V and 5-V digital interfaces through its dedicated VDDIO supply pin. PWM inputs (HIN/LIN), SPI lines, and digital comparator outputs (COMP_OUT) are fully tolerant of either logic level, enabling direct connection to common automotive MCUs without external level shifters - simplifying design and improving signal integrity.
How does DRV3245BQPHPRQ1 meet ASIL D requirements for functional safety?
DRV3245BQPHPRQ1 achieves systematic ASIL D capability per ISO 26262 through redundant internal monitors (clock, SPI CRC, analog BIST), fault-reporting architecture (nFAULT pin with diagnostic coverage >90%), documented safety analysis (FMEDA, FTA), and safety manual support. It enables end-system compliance when integrated into a properly architected safety manager - confirmed by TI's functional safety documentation package for DRV3245Q-Q1.
