Product details
Overview
DRV3245BEPHPRQ1 from Texas Instruments is an AEC-Q100 Grade 0 automotive 3-phase gate driver IC with integrated current-shunt amplifiers, phase comparators, and SPI diagnostics. It drives three half-bridge N-channel MOSFETs (2P+2N configuration), operates from 4.5 V to 45 V, supports 6-PWM/3-PWM control up to 20 kHz, and delivers programmable peak gate drive current up to 1 A for high-temperature motor control in automated transmission systems.
For engineers reviewing the DRV3245BEPHPRQ1 datasheet, DRV3245BEPHPRQ1 pinout, DRV3245BEPHPRQ1 application, or DRV3245BEPHPRQ1 equivalent, this page provides verified technical context, validated pin functions, confirmed protection features (VDS overcurrent, shoot-through prevention, real-time gate-source monitoring), thermal performance at 150°C ambient, and BOM-reducing integration of 2 shunt amplifiers and 3 phase comparators.
Technical Context
The DRV3245BEPHPRQ1 implements a charge-pump-based gate driver architecture enabling 100% duty cycle operation during cold-crank conditions down to 4.5 V battery input. Its dual-mode PWM interface accepts either 3-PWM (commutation control) or 6-PWM (independent high/low-side control) signals, with programmable dead-time insertion to prevent shoot-through.
It integrates two high-precision current-shunt amplifiers (gain = 20 V/V, bandwidth = 1 MHz) and three phase comparators with real-time digital output monitoring-distinct from the A variant's SPI-only status reporting. All internal regulators, clock monitor, SPI CRC, and analog BIST support ISO 26262 ASIL-B functional safety compliance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4.5 V to 45 V - Enables operation across automotive battery transients including cold-crank (4.5 V) and load-dump (45 V). |
| Peak Gate Drive Current | Up to 1 A - Supports fast switching of high-Qg N-channel MOSFETs in high-power BLDC/PMSM inverters. |
| Current-Shunt Amplifiers | 2 × integrated amplifiers - Reduces external sensing components; each provides 20 V/V gain and rail-to-rail output for motor phase current feedback. |
| Phase Comparators | 3 × real-time digital comparators - Deliver immediate overcurrent/short-circuit detection per phase via dedicated output pins (not SPI-only). |
| Digital Interface | 3.3 V / 5 V compatible SPI - Enables configuration, fault readback, and diagnostics without level-shifting in mixed-voltage MCU systems. |
| Operating Temperature | −40°C to +150°C (TA) - Qualified per AEC-Q100 Grade 0 for under-hood automotive applications like transfer case actuators. |
| Protection Features | VDS overcurrent, shoot-through prevention, gate-source voltage monitor, overtemperature warning - Hardware-enforced safeguards reduce software safety overhead. |
Pinout & Package
DRV3245BEPHPRQ1 uses 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 efficient heat dissipation in high-temperature environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Main supply input | 4.5–45 V input powering gate drivers, logic, and internal regulators; requires local decoupling. |
| VDDIO | Digital I/O supply | 3.3 V or 5 V supply for SPI, PWM, and nFAULT pins; independent from VDD for mixed-voltage interfacing. |
| nFAULT | Open-drain fault indicator | Active-low signal asserting on any critical fault (VDS overcurrent, overtemperature, undervoltage); pulls low without external pull-up. |
| SHUNT_A, SHUNT_B | Current-sense amplifier inputs | Differential inputs for two motor phase current measurements; internally biased and routed to dedicated amplifier outputs. |
| PHCMP_A, PHCMP_B, PHCMP_C | Phase comparator outputs | Real-time digital outputs indicating phase-specific overcurrent events; asserted immediately without SPI polling delay. |
| HINx / LINx (x=1–3) | PWM input terminals | Accept 3-PWM (HIN1–3 only) or 6-PWM (HIN/LIN pairs) control; support up to 20 kHz switching frequency. |
| OUTxH / OUTxL (x=1–3) | Gate drive outputs | High-side and low-side gate drive outputs per phase; each capable of sourcing/sinking 1 A peak for robust MOSFET turn-on/turn-off. |
Key Features
| Feature | Design Value |
|---|---|
| Charge-pump gate driver | Enables 100% duty cycle operation at low battery voltages (down to 4.5 V), eliminating need for external boost circuitry during cold-crank. |
| Real-time phase comparator outputs | Three dedicated digital pins provide immediate overcurrent detection per motor phase-critical for fast-acting hardware safety interlocks. |
| Integrated shunt amplifiers | Two precision amplifiers (20 V/V, 1 MHz BW) reduce component count and PCB area versus discrete op-amp + resistor networks. |
| Programmable dead-time control | Configurable via SPI to prevent shoot-through during high-side/low-side switching transitions, supporting diverse MOSFET timing requirements. |
| Functional safety support | Includes clock monitor, SPI CRC, analog BIST, and regulator monitors-enabling ASIL-B compliant system design per ISO 26262 without external safety controllers. |

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 |
|---|---|---|---|
| DRV3245AEPHPRQ1 | Features 3 current-shunt amplifiers and SPI-only phase comparator status (no real-time digital outputs). | Better suited for systems using MCU-based current reconstruction and centralized fault handling via SPI polling. | Select when full 3-shunt sensing is required and real-time comparator outputs are unnecessary. |
| UCC27282QDQNRQ1 | 6-channel high-speed gate driver only-no integrated shunt amps, comparators, or diagnostics; requires external sensing and protection. | Used in higher-frequency (>100 kHz) inverters where integrated diagnostics are handled separately by MCU or safety ASIC. | Select when maximum switching speed is prioritized over integration, and system-level functional safety is implemented externally. |
Compared with DRV3245AEPHPRQ1, the DRV3245BEPHPRQ1 trades one shunt amplifier for deterministic real-time comparator outputs-ideal for hardware-triggered safety responses. Versus UCC27282QDQNRQ1, it delivers significant BOM and layout simplification at the cost of fixed-function integration, making it optimal for cost- and space-constrained automotive actuators.

FAQ
What is the key functional difference between DRV3245BEPHPRQ1 and DRV3245AEPHPRQ1?
The DRV3245BEPHPRQ1 integrates two current-shunt amplifiers and three real-time digital phase comparator outputs, whereas the DRV3245AEPHPRQ1 provides three shunt amplifiers with phase comparator status reported exclusively via SPI. This makes DRV3245BEPHPRQ1 better suited for hardware-triggered fault responses, while DRV3245AEPHPRQ1 supports more granular current reconstruction. Both share identical gate drive capability, protection features, and package.
Does DRV3245BEPHPRQ1 support 100% duty cycle operation, and how is it achieved?
Yes, DRV3245BEPHPRQ1 supports 100% duty cycle operation through an integrated charge-pump gate driver that maintains high-side gate voltage even at minimum input voltage (4.5 V). This eliminates reliance on external bootstrap circuits and ensures reliable MOSFET turn-on during automotive cold-crank conditions-critical for uninterrupted actuator control in safety-critical systems.
What protection features are implemented in hardware versus those requiring SPI configuration in DRV3245BEPHPRQ1?
Hardware-enforced protections in DRV3245BEPHPRQ1 include MOSFET shoot-through prevention, VDS overcurrent detection, gate-source voltage monitoring, and overtemperature warning-all active without SPI intervention. Programmable features such as dead-time control, fault response behavior, and diagnostic thresholds require SPI configuration but do not affect baseline safety operation.
Can DRV3245BEPHPRQ1 be used with both 3.3-V and 5-V microcontrollers?
Yes, DRV3245BEPHPRQ1 supports dual-voltage digital I/O: its VDDIO pin accepts either 3.3 V or 5 V, allowing direct interface with common automotive MCUs (e.g., TI C2000™, NXP S32K) without level-shifting circuitry. The SPI interface, PWM inputs, and nFAULT output are all compatible with both logic families, simplifying system integration.
What is the thermal performance limit of DRV3245BEPHPRQ1, and how is it validated?
DRV3245BEPHPRQ1 is qualified for operation from −40°C to +150°C ambient temperature (Grade 0 per AEC-Q100), with thermal performance validated via junction-to-case resistance (RθJC) testing and PowerPAD-enhanced HTQFP packaging. Its exposed thermal pad enables ≤2.5°C/W junction-to-board resistance when properly soldered-ensuring reliable operation in under-hood environments exceeding 135°C.
