Product details
Overview
DRV8353HRTAR from Texas Instruments is a 9–75-V, three-phase smart gate driver IC for N-channel MOSFETs in BLDC motor control systems. It integrates triple low-side current shunt amplifiers (gain-selectable: 5/10/20/40 V/V), adjustable slew-rate control, 50–1000 mA peak gate drive current, and VM undervoltage lockout - enabling compact, high-efficiency e-bike and power tool motor drives.
For engineers reviewing the DRV8353HRTAR datasheet, DRV8353HRTAR pinout, DRV8353HRTAR application, or DRV8353HRTAR equivalent, this page delivers verified technical context, validated pin functions, confirmed protection features (OCP, shoot-through prevention, thermal shutdown), and real-world motor control use cases - all aligned to TI's SLVSDY6A production data sheet.
Technical Context
The DRV8353HRTAR implements Smart Gate Drive (SGD) architecture with VGS handshake logic and programmable dead-time insertion to prevent shoot-through across all three half-bridges. Its integrated charge pump supports 100% PWM duty cycle operation, while the strong pulldown circuit mitigates dV/dt-induced parasitic turn-on.
This variant uses hardware-only interface (no SPI), includes triple shunt amplifiers (SNA/SNB/SNC inputs; SOA/SOB/SOC outputs), and omits the integrated buck regulator - distinguishing it from DRV8353R variants. It operates with 6x, 3x, 1x, or independent PWM modes and supports 120° sensored commutation via internal lookup table.
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 24–72-V battery systems in e-mobility. |
| Gate Drive Current | 50 mA to 1 A peak source / 100 mA to 2 A peak sink - enables fast switching of medium-power N-MOSFETs with controlled EMI. |
| Current Sense | Triple integrated shunt amplifiers with selectable gain (5/10/20/40 V/V) - supports bidirectional or unidirectional motor phase current measurement. |
| Protection Features | VM UVLO, GDUV, VDS overcurrent, shoot-through prevention, thermal warning/shutdown, and open-drain nFAULT output - enables robust field operation without external fault management. |
| Control Interface | Hardware-only (H-mode): 6x/3x/1x/independent PWM inputs - reduces MCU GPIO count and eliminates SPI configuration overhead. |
| Package & Thermal | 40-pin WQFN (6.0 mm × 6.0 mm, 0.5-mm pitch) with exposed thermal pad - supports >3 W continuous power dissipation with proper PCB copper area. |
Pinout & Package
DRV8353HRTAR is housed in a 40-pin WQFN package (RTA suffix) with 6.0 mm × 6.0 mm body and exposed thermal pad for enhanced thermal performance. Pin assignment follows TI's standardized layout for DRV8353 family devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GHA, GHB, GHC | High-side gate driver outputs | Drive gates of upper N-MOSFETs; each capable of 1-A peak sink current for fast turn-off. |
| GLA, GLB, GLC | Low-side gate driver outputs | Drive gates of lower N-MOSFETs; support independent PWM control per phase leg. |
| INHA–INLC | PWM input controls | Hardware interface pins accepting 3.3-V/5-V logic; enable 6x, 3x, or 1x commutation modes. |
| SHA–SHC, SPA–SPC, SNA–SNC | Current sense inputs | Accept shunt resistor connections for high- and low-side sensing; feed integrated amplifiers with configurable gain. |
| SOA–SOC | Shunt amplifier outputs | Analog outputs (rail-to-rail) delivering amplified current signals directly to MCU ADC or external signal chain. |
| nFAULT | Fault indicator | Open-drain output pulled low during any fault condition (OCP, OTSD, shoot-through); requires external pull-up. |
| ENABLE | Global enable | Logic-low entry into 20-µA sleep mode; 8–40-µs pulse resets latched faults. |
| VCP, CPH, CPL, VDRAIN | Charge pump network | Support high-side gate drive at 100% duty cycle; VDRAIN referenced to MOSFET drain node for accurate VDS monitoring. |
Key Features
| Feature | Design Value |
|---|---|
| Smart Gate Drive (SGD) architecture | Integrates VGS handshake and minimum dead-time insertion - eliminates need for external shoot-through protection logic. |
| Adjustable slew-rate control | Configurable via IDRIVE pin (7-level resistor setting) - balances EMI reduction against switching loss in high-frequency BLDC operation. |
| Triple integrated shunt amplifiers | Gain-selectable (5/10/20/40 V/V) with dedicated inputs (SNA/SNB/SNC) and outputs (SOA/SOB/SOC) - enables full 3-phase current reconstruction without external op-amps. |
| 120° sensored trapezoidal control | Internal commutation table activated in 1x PWM mode - reduces MCU firmware complexity for hall-sensor-based BLDC drives. |
| Robust fault management | Dedicated nFAULT pin with latching behavior and reset-by-pulse capability - simplifies system-level fault response and diagnostics. |
Applications
| E-Bike Motor Controller | Power Tool Motor Drive |

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 |
|---|---|---|---|
| DRV8353SRTAR | Same package and pinout, but SPI interface instead of hardware PWM; includes same shunt amplifiers and protections. | Requires MCU SPI peripheral and firmware register configuration; better suited for FOC systems needing dynamic parameter updates. | Select DRV8353SRTAR when runtime reconfiguration (e.g., gain, OCP threshold) is required; DRV8353HRTAR is optimal for fixed-function, low-latency hardware control. |
| DRV8323RSRTAT | 40-V max VM, no integrated shunt amplifiers, SPI-only interface, smaller 32-pin WQFN package. | Lacks current sensing - mandates external amplifiers; limited to lower-voltage tools/fans; lower thermal capacity. | Choose DRV8323RSRTAT only for cost-sensitive, <40-V applications where external current sensing is acceptable and board space is constrained. |
Compared with DRV8353SRTAR and DRV8323RSRTAT, the DRV8353HRTAR uniquely combines hardware simplicity, integrated current sensing, and 75-V operation - making it the most direct fit for high-voltage, low-firmware-overhead BLDC drives in e-mobility and power tools.

FAQ
What is the maximum VM supply voltage supported by the DRV8353HRTAR?
The DRV8353HRTAR supports a VM supply range of 9 V to 75 V, as specified in the absolute maximum ratings and recommended operating conditions of TI's SLVSDY6A datasheet. Operation above 75 V risks permanent damage to internal charge pump and gate driver stages. For 72-V battery systems, ensure transient spikes remain within this limit using appropriate clamping or filtering.
Does the DRV8353HRTAR include an integrated buck regulator?
No, the DRV8353HRTAR does not include an integrated buck regulator. It belongs to the "H" variant (hardware interface, no buck), unlike the "R" variants (e.g., DRV8353R) which integrate the LM5008A buck converter. Power for external controllers must be supplied separately or derived from DVDD (5 V, 10 mA) or VGLS (11 V, higher current) rails.
How many current shunt amplifiers are integrated in the DRV8353HRTAR?
DRV8353HRTAR integrates three fully differential current shunt amplifiers - one per motor phase - with configurable gain (5/10/20/40 V/V) set via the GAIN pin. Inputs include SNA/SNB/SNC (low-side shunt) and SPA/SPB/SPC (combined low-side source + shunt high-side), supporting both unidirectional and bidirectional current measurement.
What PWM control modes does the DRV8353HRTAR support?
The DRV8353HRTAR supports four hardware-configurable PWM modes: 6x (six independent inputs), 3x (three high-side + three low-side enables), 1x (single PWM + direction/control logic), and independent (per-phase enable). Mode selection is set via resistor on the MODE pin and enables flexible MCU interface scaling without SPI overhead.
Is the DRV8353HRTAR pin-compatible with other DRV835x devices?
DRV8353HRTAR uses a 40-pin WQFN (RTA) package and is pin-compatible with DRV8353SRTAR (same footprint and pin functions), but not with 32-pin DRV8350 or 48-pin DRV8353R variants. Critical differences include missing buck-related pins (FB, SW, VIN) and presence of shunt amplifier I/O (SNA–SOC), confirming strict compatibility only within the 40-pin H/S variants.
