Product details
Overview
DRV8353RHRGZR from Texas Instruments is a 9–75-V, three-phase smart gate driver IC with integrated triple shunt amplifiers, buck regulator (350 mA output), and SPI/hardware interface. It drives N-channel MOSFETs in BLDC motor control systems using field-oriented or trapezoidal commutation, featuring VGS handshake, adjustable slew rate, and shoot-through prevention.
For engineers reviewing the DRV8353RHRGZR datasheet, DRV8353RHRGZR pinout, DRV8353RHRGZR application, or DRV8353RHRGZR equivalent, this page delivers verified technical context, validated pin functions, confirmed protection features (VM UVLO, VDS OCP, thermal shutdown), and real-world motor control use cases - all grounded in TI's SLVSDY6A production datasheet.
Technical Context
The DRV8353RHRGZR implements Smart Gate Drive (SGD) architecture with programmable dead-time insertion, dV/dt-mitigating pulldown circuits, and VGS monitoring to prevent gate short-circuit failures. Its charge pump supports 100% PWM duty cycle for high-side N-MOSFETs, while the integrated LM5008A-based buck regulator operates from 6–95 V input and delivers 2.5–75 V at 350 mA.
It integrates three independent current shunt amplifiers with selectable gain (5/10/20/40 V/V) and bidirectional/unidirectional support, plus six configurable PWM modes (6x, 3x, 1x, independent) - including internal commutation table for sensored trapezoidal control - reducing MCU I/O count and simplifying BLDC system design.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | 9–75 V VM input; enables direct connection to battery rails in e-mobility and power tools. |
| Gate Drive Current | 50 mA–1 A peak source / 100 mA–2 A peak sink; supports fast switching of high-Qg MOSFETs with adjustable strength. |
| Buck Regulator | 350 mA output, 2.5–75 V adjustable; powers external MCU or sensors without discrete DC/DC converter. |
| Current Sense | Triple integrated shunt amplifiers with 4 gain options; eliminates need for external op-amps in motor phase current feedback. |
| Protection Features | VM UVLO, GDUV, VDS overcurrent, shoot-through prevention, thermal warning/shutdown, nFAULT indicator; reduces external fault-handling circuitry. |
| Interface Options | SPI or hardware (H/W) control mode; allows flexible integration with low-pin-count MCUs or deterministic real-time controllers. |
| Low-Power Mode | 20 µA sleep current at 48 V VM; extends battery life in portable BLDC applications like e-bikes and drones. |
Pinout & Package
VQFN-48 package (7.0 mm × 7.0 mm, 0.5-mm pitch) with exposed thermal pad; optimized for high-power motor drive thermal dissipation and PCB layout compactness.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GHA, GHB, GHC | High-side gate driver outputs | Drive gates of three high-side N-MOSFETs; each supports 1-A peak source/2-A peak sink. |
| GLA, GLB, GLC | Low-side gate driver outputs | Drive gates of three low-side N-MOSFETs; compatible with standard half-bridge configurations. |
| INHA–INLC | PWM control inputs | Accept 3-phase high/low-side logic signals; support 6x, 3x, 1x, or independent PWM modes. |
| SHA–SHC, SLA–SLC | Current sense inputs | Connect to high/low-side MOSFET sources for inline shunt resistor measurement; enable three-phase current reconstruction. |
| nFAULT | Open-drain fault indicator | Asserts low on any fault (OCP, OTSD, UVLO); requires external pullup; simplifies system-level fault reporting. |
| ENABLE | Global gate driver enable | Logic-low entry into 20-µA sleep mode; 8–40-µs pulse resets latched faults without full power cycle. |
| FB, VIN, SW, BST, VCC | Buck regulator interface | Enable closed-loop regulation of buck output (2.5–75 V); VIN accepts 6–95 V, supporting wide-input industrial supplies. |
| CPH, CPL, VCP, VDRAIN | Charge pump network | Generate high-side gate drive voltage > VM; support 100% duty cycle operation without external bootstrap diodes/caps. |
Key Features
| Feature | Design Value |
|---|---|
| Smart Gate Drive (SGD) architecture | Automatically inserts minimum dead time and enforces VGS handshake to eliminate shoot-through risk across temperature/voltage. |
| Adjustable slew rate control | Reduces EMI by tuning MOSFET switching edge rates via external resistor; avoids costly board-level filtering. |
| Integrated triple shunt amplifiers | Replace three external op-amp + reference circuits; support bidirectional current sensing for FOC with <1% gain error. |
| Configurable PWM modes | 1x mode uses internal commutation table for sensor-based trapezoidal control - cuts MCU GPIO usage by 50% vs. 6x mode. |
| Comprehensive fault protection | Detects and responds to VM undervoltage, gate supply UVLO, VDS overcurrent, and thermal events - all with single nFAULT pin. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar three-phase gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRV8353SRTAT | Same 40-pin WQFN package; lacks integrated buck regulator (no VIN/FB/SW pins); retains triple shunt amplifiers and SPI interface. | Requires external 5–12-V supply for MCU/logic; suitable where board space permits discrete DC/DC and cost sensitivity outweighs integration benefit. | Select when buck regulator is unnecessary and smaller footprint (6×6 mm vs. 7×7 mm) is critical. |
| MP6550GQZ | 48-pin QFN, 4.5–60-V operation, no integrated shunt amps or buck; supports only hardware PWM; max 0.6-A gate drive. | Lacks current sensing and regulated supply - mandates external amplifiers and LDOs; limited to simpler sensored trapezoidal control. | Choose for cost-driven, lower-voltage (<60 V), low-complexity BLDC systems where integration is secondary to unit price. |
Compared with DRV8353SRTAT and MP6550GQZ, the DRV8353RHRGZR uniquely combines buck regulation, triple shunt amplifiers, and SPI configurability in a single 7×7-mm VQFN - enabling fully self-contained motor control subsystems with minimal external components.

FAQ
What is the maximum VM supply voltage supported by the DRV8353RHRGZR?
The DRV8353RHRGZR supports a VM supply range of 9 V to 75 V, as specified in the absolute maximum ratings and recommended operating conditions of the SLVSDY6A datasheet. This enables direct connection to common battery packs used in e-bikes (36–48 V), cordless power tools (18–60 V), and industrial 48-V DC systems - with built-in VM undervoltage lockout (UVLO) ensuring safe startup and shutdown behavior.
Does the DRV8353RHRGZR include an integrated buck regulator, and what are its output capabilities?
Yes, the DRV8353RHRGZR integrates an LM5008A-based buck regulator capable of delivering up to 350 mA at an adjustable output voltage from 2.5 V to 75 V. The regulator accepts input from VIN (6–95 V), uses external FB resistors for precise voltage setting, and supports synchronous rectification via SW and BST pins - allowing it to power external microcontrollers, sensors, or logic circuitry without requiring a separate DC/DC converter.
How does the DRV8353RHRGZR implement current sensing, and what amplifier gain options are available?
The DRV8353RHRGZR integrates three matched current shunt amplifiers with user-selectable gain settings of 5, 10, 20, or 40 V/V, configured via the GAIN pin using an external resistor. These amplifiers accept inputs from both high-side (SHA–SHC) and low-side (SLA–SLC) MOSFET sources, supporting bidirectional or unidirectional current measurement - enabling accurate phase current reconstruction for field-oriented control without external op-amps or precision references.
What protection features are built into the DRV8353RHRGZR, and how are faults reported?
The DRV8353RHRGZR includes VM undervoltage lockout (UVLO), gate drive supply undervoltage (GDUV), MOSFET VDS overcurrent protection (OCP), shoot-through prevention, gate driver fault (GDF), thermal warning/shutdown (OTW/OTSD), and fault condition indication via the open-drain nFAULT pin. When any fault occurs, nFAULT pulls low and remains latched until cleared by an 8–40-µs ENABLE pulse - providing simple, reliable system-level fault signaling.
Can the DRV8353RHRGZR operate in both SPI and hardware PWM modes, and how is the mode selected?
Yes, the DRV8353RHRGZR supports both SPI serial interface and hardware (H/W) PWM control modes. Mode selection is determined by the presence or absence of an external pullup/pulldown on the MODE pin (a 4-level resistor-programmable input). In H/W mode, six dedicated INx pins accept direct PWM signals; in SPI mode, all configuration and status registers are accessed via SCLK, SDI, SDO, and nSCS - offering flexibility for resource-constrained or feature-rich motor control implementations.
