Product details
Overview
DRV8300DPWRQ1 from Texas Instruments is an AEC-Q100 Grade 0 (–40°C to +150°C) automotive 3-phase gate driver IC for 48-V motor control systems. It delivers 2-A peak source / 2.5-A peak sink gate drive current, supports 90-V MOSFET VDS transient rating, and integrates three configurable current shunt amplifiers and dual Active Short Circuit (ASC) capability on high-side and low-side FETs. It is used in belt-integrated starter generators (BISG) and electric turbochargers.
For engineers reviewing the DRV8300DPWRQ1 datasheet, DRV8300DPWRQ1 pinout, DRV8300DPWRQ1 application, or DRV8300DPWRQ1 equivalent, key selection criteria include its 64-pin HTQFP package with exposed thermal pad, SPI interface with CRC, 12-V/48-V split supply architecture, and ASIL-D-targeted functional safety compliance for high-reliability 48-V traction and actuation systems.
Technical Context
The DRV8300DPWRQ1 implements a three-channel N-channel half-bridge gate driver with independent bootstrap and charge-pump circuitry enabling 100% duty-cycle PWM operation. Its power architecture is optimized for 48-V DC-link applications with 95-V absolute maximum DHCP rating and 105-V bootstrap voltage support.
It features integrated diagnostics including MOSFET VDS overcurrent monitors, Rshunt overcurrent detection, VGS fault sensing, analog built-in self-test, and thermal warning/shutdown - all coordinated via a configurable SPI interface supporting 3.3-V and 5-V logic inputs.

Use Value: Delivers 90-V MOSFET support and 105-V bootstrap rating to sustain operation during exhaust pressure surges, while integrated shunt amps reduce latency in current loop bandwidth. |
| Electric Power Steering (EPS) | HVAC Compressor |
Use Scenario: 48-V EPS system delivering high assist torque at low speeds and efficient operation at highway speeds. IC Role / Device Role / Timing Role: Gate driver for three-phase inverter supplying brushless DC motor; executes space-vector PWM with synchronized current sampling and thermal derating.

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 |
|---|---|---|---|
| DRV3256-Q1 | Same 64-pin HTQFP package, identical 2-A/2.5-A drive strength, 3-shunt amp, and HS+LS ASC; adds watchdog timer and extended register set (PVDD_UV2_LVL2, SD_MODE_SEL) | Supports more complex fault-handling sequences and deeper system-level integration in ASIL-D architectures | Select DRV3256-Q1 when advanced SPI configurability and watchdog supervision are required beyond baseline ASC and current sensing |
| UCC5870-Q1 | Isolated dual-channel gate driver (not 3-phase); 10-A peak drive, 5.7-kVRMS isolation, no integrated shunt amps or ASC | Used in high-voltage traction inverters (>400 V) where galvanic isolation is mandatory, not in 48-V non-isolated BISG/eTurbo systems | Choose UCC5870-Q1 only for isolated high-voltage inverter stages; not a functional substitute for DRV8300DPWRQ1's integrated 3-phase, non-isolated, current-sensing architecture |
Compared with DRV3256-Q1, DRV8300DPWRQ1 offers identical core gate drive and protection functionality but omits the watchdog timer and extended register bits-making it optimal for cost-sensitive, functionally focused 48-V motor drives where those features are unused. Versus UCC5870-Q1, it provides native 3-phase integration and current sensing at lower voltage, eliminating isolation components and reducing system complexity for 48-V applications.

FAQ
What is the maximum DC-link voltage supported by the DRV8300DPWRQ1?
The DRV8300DPWRQ1 supports a DC-link voltage range of 20 V to 90 V on its PVDD pin, with an absolute maximum rating of 95 V for transient conditions such as load dump. This enables robust operation in 48-V automotive systems where voltage spikes up to 95 V must be tolerated without device failure or latch-up.
Does the DRV8300DPWRQ1 support 100% duty-cycle PWM operation?
Yes, the DRV8300DPWRQ1 supports true 100% duty-cycle PWM operation through its integrated charge pump circuitry, which maintains bootstrap voltage during sustained high-side conduction. This eliminates the need for external bootstrap diodes or auxiliary supplies and is essential for field-oriented control schemes requiring continuous conduction mode.
How many current shunt amplifiers are integrated into the DRV8300DPWRQ1?
DRV8300DPWRQ1 integrates three precision current shunt amplifiers-one per phase-enabling simultaneous low-side current sensing across all three motor phases. Each amplifier features programmable gain and filtering, and outputs are routed directly to external ADCs or internal monitoring circuits without external op-amp components.
What functional safety level does the DRV8300DPWRQ1 target?
The DRV8300DPWRQ1 is designed to support ASIL-D system-level compliance per ISO 26262. It includes dual-core monitoring, clock and regulator supervision, analog built-in self-test, fault-tolerant SPI with CRC, and hardware-based fault signaling (nFAULT pin), all documented to aid functional safety analysis in automotive motor control applications.
What package type and thermal requirements apply to the DRV8300DPWRQ1?
DRV8300DPWRQ1 uses a 64-pin HTQFP (PAP) package measuring 10.0 mm × 10.0 mm with an exposed thermal pad (PowerPAD™). The thermal pad must be soldered to a dedicated PCB copper pour for effective heat dissipation, enabling operation at full rated current up to +150°C ambient temperature per AEC-Q100 Grade 0 requirements.
