Product details
Overview
DRV8353SRTAR from Texas Instruments is a 9–75-V, three-phase smart gate driver IC with integrated triple shunt amplifiers, SPI interface, and 350-mA buck regulator. It drives N-channel MOSFETs in BLDC motor control systems using field-oriented or trapezoidal commutation, supporting 6x/3x/1x PWM modes and VDS-based overcurrent protection.
For engineers reviewing the DRV8353SRTAR datasheet, DRV8353SRTAR pinout, DRV8353SRTAR application, or DRV8353SRTAR equivalent, this page delivers verified technical context, validated pin functions, confirmed current-sense architecture, and real-world motor-control use cases - all aligned to TI's SLVSDY6A production data sheet.
Technical Context
The DRV8353SRTAR implements Smart Gate Drive (SGD) architecture with adjustable slew-rate control, VGS handshake logic, and minimum dead-time insertion to prevent shoot-through. Its charge pump enables 100% duty-cycle high-side drive, 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), supports bidirectional sensing, and provides dedicated analog outputs (SOA/SOB/SOC) referenced to VREF. Fault handling includes VM UVLO, GDUV, VDS OCP, thermal warning/shutdown, and open-drain nFAULT signaling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 9 V to 75 V on VM pin - powers gate drivers and internal regulators; compatible with 12–48-V battery systems and industrial DC bus rails. |
| Buck Regulator Output | 2.5–75 V at 350 mA - configurable via FB resistor divider; powers external MCU or sensors without auxiliary supply. |
| Gate Drive Current | 50 mA to 1 A peak source / 100 mA to 2 A peak sink - programmable via IDRIVE pin; enables fast turn-on/turn-off of high-Qg MOSFETs. |
| Current Sense Gain | Selectable 5/10/20/40 V/V - set by GAIN pin resistor; supports ±50-mV shunt inputs for precise phase-current measurement. |
| SPI Interface | Full-duplex, 4-wire (nSCS/SCLK/SDI/SDO) - enables register read/write, fault status polling, and dynamic configuration without hardware mode pins. |
| Fault Protection | VM UVLO, GDUV, VDS OCP, shoot-through prevention, OTW/OTSD - all asserted via open-drain nFAULT pin with automatic latch or auto-retry behavior. |
| Operating Temperature | –40°C to 125°C junction - qualified for e-bike, power tool, and industrial motor drive environments with extended thermal margin. |
Pinout & Package
DRV8353SRTAR is housed in a 40-pin WQFN package (6.00 mm × 6.00 mm, 0.5-mm pitch) with exposed thermal pad for enhanced power dissipation in motor-drive applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GHA, GHB, GHC | High-side gate driver outputs | Drive gates of upper-leg N-MOSFETs; each capable of 1-A peak source/2-A sink with slew control. |
| GLA, GLB, GLC | Low-side gate driver outputs | Drive gates of lower-leg N-MOSFETs; support synchronous rectification and 100% duty-cycle operation. |
| INHA–INLC | PWM input controls | Direct logic-level inputs for 6x PWM mode; enable simple microcontroller interfacing without SPI. |
| nSCS, SCLK, SDI, SDO | SPI interface signals | Enable full register access, real-time fault monitoring, and dynamic parameter adjustment (e.g., IDRIVE, GAIN, VDS threshold). |
| SOA, SOB, SOC | Shunt amplifier outputs | Analog outputs for phase currents; rail-to-rail swing referenced to VREF (2.5 V); require external ADC sampling. |
| VREF | Shunt amp reference | 2.5-V precision reference for SOx outputs; decoupled with 0.1-µF ceramic capacitor to AGND. |
| nFAULT | Fault indicator | Open-drain output pulled low during any fault condition; requires external pullup for system-level interrupt signaling. |
| ENABLE | Global enable | Active-low input; asserts sleep mode (20 µA quiescent) and accepts 8–40-µs pulse to clear latched faults. |
Key Features
| Feature | Design Value |
|---|---|
| Smart Gate Drive (SGD) Architecture | Integrates VGS handshake, adaptive dead-time insertion, and dV/dt-mitigating pulldown - eliminates external shoot-through protection circuitry. |
| Triple Integrated Shunt Amplifiers | Configurable gain (5–40 V/V), bidirectional support, and dedicated analog outputs - enable FOC-compliant current sensing without external op-amps or isolators. |
| Programmable Gate Drive Strength | 7-level IDRIVE setting via external resistor - balances switching loss vs. EMI across diverse MOSFET Qg values and PCB layouts. |
| Integrated Buck Regulator | LM5008A-based, 6–95-V input, 2.5–75-V/350-mA output - reduces BOM count by powering MCU, sensors, or level-shifters from same VM rail. |
| Comprehensive Fault Coverage | Detects VM undervoltage, gate supply fault, VDS overcurrent, thermal events, and shoot-through - all reported via single nFAULT pin with configurable latch behavior. |

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 |
|---|---|---|---|
| DRV8353HRTAR | Hardware-only interface (no SPI); identical pinout, package, and analog features. | Lacks register configurability - suitable only for fixed-function 6x/3x PWM systems without runtime tuning. | Choose DRV8353HRTAR when SPI complexity is unnecessary and cost reduction is prioritized over diagnostics or dynamic gain adjustment. |
| DRV8323RSRTAT | 40-V max VM, no integrated buck, SPI-only interface, 3-shunt amps - smaller footprint (32-pin WQFN), lower voltage rating. | Targeted at 12–24-V battery tools and drones; lacks VDS OCP and thermal shutdown robustness of DRV8353SRTAR. | Choose DRV8323RSRTAT for space-constrained, lower-voltage designs where external 5-V supply exists and full protection coverage is secondary. |
Compared with DRV8353HRTAR and DRV8323RSRTAT, the DRV8353SRTAR uniquely combines SPI configurability, 75-V operation, integrated buck regulation, and comprehensive fault reporting - making it optimal for scalable, high-reliability BLDC systems demanding both flexibility and ruggedness.

FAQ
What is the maximum VM supply voltage supported by the DRV8353SRTAR?
The DRV8353SRTAR 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 allows direct integration into 48-V battery systems and industrial DC bus applications without external step-down stages. The device remains fully functional across this range, including gate drive strength, buck regulator regulation, and fault detection thresholds.
Does the DRV8353SRTAR include an integrated buck regulator, and what are its output capabilities?
Yes, the DRV8353SRTAR integrates an LM5008A-based buck regulator with input range 6–95 V and programmable output from 2.5 V to 75 V at up to 350 mA. Output voltage is set via external FB resistor divider; typical configurations deliver 3.3 V or 5 V for MCU or sensor biasing. The regulator includes thermal foldback and overcurrent protection, and its SW pin connects to external inductor/diode.
How does the DRV8353SRTAR implement current sensing, and what interfaces does it provide for reading phase currents?
The DRV8353SRTAR integrates three matched shunt amplifiers with selectable gain (5/10/20/40 V/V) and dedicated analog outputs (SOA/SOB/SOC). Each amplifier accepts differential inputs from low-side shunts (via SNA/SNB/SNC and SPA/SPB/SPC) and references to VREF (2.5 V). These outputs are continuous analog signals requiring external ADC sampling - no digital current readout is performed internally.
What protection features are implemented in the DRV8353SRTAR, and how are faults signaled to the system controller?
The DRV8353SRTAR implements VM undervoltage lockout (UVLO), gate drive supply undervoltage (GDUV), VDS overcurrent protection (OCP), shoot-through prevention, gate driver fault (GDF), thermal warning/shutdown (OTW/OTSD), and fault condition indication. All faults assert the open-drain nFAULT pin low; latched or auto-retry behavior is configurable via SPI register bits. No separate fault pins are provided - centralized signaling simplifies interrupt handling.
Can the DRV8353SRTAR operate in standalone mode without SPI communication?
Yes, the DRV8353SRTAR supports hardware-only operation using INHA–INLC and MODE pins for 6x/3x/1x PWM control - no SPI required. Default settings (e.g., IDRIVE, GAIN, VDS threshold) are established by external resistors on IDRIVE, GAIN, VDS, and MODE pins. SPI is optional for dynamic reconfiguration, diagnostics, and advanced fault logging but not mandatory for basic gate-driving functionality.
