Product details
Overview
DRV8317HREER from Texas Instruments is a three-phase BLDC motor driver IC with integrated 5-A peak MOSFET half-bridges, programmable current-sense gain (0.25–2 V/A), configurable slew rate (13.75–320 V/µs), and 4.5–20-V operation. It delivers ultra-low 3-µA sleep current and supports up to 200-kHz PWM for high-efficiency fan, pump, and drone motor control.
For engineers reviewing the DRV8317HREER datasheet, DRV8317HREER pinout, DRV8317HREER application, or DRV8317HREER equivalent, this page provides verified technical context, validated pin functions, confirmed protection thresholds (UVLO: 4.4 V, OVP: 22 V), and hardware-configurable interface behavior - all specific to the DRV8317H variant in 36-pin WQFN.
Technical Context
The DRV8317HREER implements a pin-configurable 6x/3x PWM control architecture with four-level MODE, SLEW, and GAIN inputs enabling direct microcontroller interfacing without SPI. Its integrated current sensing eliminates external shunts, delivering three-phase SOA/SOB/SOC outputs with ±5-A full-scale range and <±5% gain error across temperature.
It integrates a 3.3-V/80-mA LDO regulator, charge pump for high-side gate drive, and comprehensive fault management including VM UVLO/OVP, CP UVLO, overcurrent (9.5-A trip), and FET overtemperature warning/shutdown (125°C/160°C). All protections feature fixed 5-ms auto-retry in hardware variant mode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Voltage | 4.5–20 V (24-V absolute max); enables direct use with 2s–4s Li-ion or 5/9/12/18-V DC rails. |
| Peak Output Current | 5 A per phase; sufficient for mid-power BLDC motors in vacuum robots and dishwasher pumps. |
| RDS(ON) (HS+LS) | 130 mΩ typical at 25°C; minimizes conduction loss and thermal rise under continuous load. |
| Sleep Current | 3 µA max at 12 V / 25°C; extends battery life in portable devices during idle periods. |
| PWM Frequency Support | Up to 200 kHz; allows high-resolution sinusoidal or FOC control with reduced audible noise. |
| Current Sense Gain | 0.25–2 V/A (4-level pin-selectable); matches sensor resolution to motor current range without firmware change. |
| VM UVLO Threshold | 4.4 V (rising), 4.2 V (falling); prevents erratic operation during brown-out conditions. |
| OCP Trip Level | 9.5 A typical; protects MOSFETs and motor windings against short-circuit faults. |
Pinout & Package
DRV8317HREER uses a 36-pin WQFN package (5.00 mm × 4.00 mm) with exposed thermal pad connected to AGND. Pin configuration is optimized for three-phase motor control with dedicated INHA/INHB/INHC and INLA/INLB/INLC inputs, OUTA/OUTB/OUTC half-bridge outputs, and hardware configuration pins (MODE, SLEW, GAIN).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| nSLEEP | Active-low sleep enable | Drives device into 3-µA sleep mode; 15–50-µs pulse resets faults without sleep entry. |
| nFAULT | Open-drain fault indicator | Pulled low on UVLO, OVP, OCP, OTW/OTS, or CPUV; requires external AVDD pull-up. |
| INHA/INHB/INHC | High-side PWM inputs | Direct logic-level control of upper MOSFETs in 6x or 3x commutation schemes. |
| INLA/INLB/INLC | Low-side PWM inputs | Direct logic-level control of lower MOSFETs; used only in 6x PWM mode. |
| OUTA/OUTB/OUTC | Half-bridge motor outputs | Paired source/sink terminals per phase; rated for 24-V abs max and 5-A peak. |
| SOA/SOB/SOC | Current sense amplifier outputs | Analog outputs proportional to phase current (±5 A full scale); no external resistor needed. |
| MODE | 4-level PWM mode select | Selects 6x PWM, 3x PWM, or two hybrid modes via voltage divider or direct tie-off. |
| SLEW | 4-level slew rate control | Configures rising/falling edge rates (13.75–320 V/µs) to balance EMI vs. switching loss. |
| GAIN | 4-level current sense gain | Sets CSA gain (0.25/0.5/1/2 V/A) to match motor current range and ADC resolution. |
| VM | Main power supply input | Connects to motor bus (4.5–20 V); bypassed with 0.1-µF + bulk capacitor to PGND. |
| AVDD | LDO-regulated output | 3.3-V ±4.5%, 80-mA supply for MCU, Hall sensors, or logic; decoupled with 4.7-µF ceramic. |
| CSAREF | Current sense reference | Stabilizes CSA offset; requires 0.1-µF ceramic to AGND for accurate low-current sensing. |
Key Features
| Feature | Design Value |
|---|---|
| Hardware-configurable interface | Eliminates SPI dependency: MODE/SLEW/GAIN pins enable full setup without firmware overhead or serial bus. |
| Integrated 3-phase current sensing | Removes need for three external shunt resistors and associated op-amps, reducing BOM cost and PCB area. |
| Programmable slew rate | Four discrete edge rates allow EMI optimization per application - e.g., slower edges for vacuum robot EMC compliance. |
| Ultra-low sleep current | 3-µA max ensures >1-year battery standby in portable BLDC systems like handheld gimbals or coffee machines. |
| Built-in 3.3-V LDO | 80-mA regulated output powers external MCU or sensors, removing need for separate voltage regulator IC. |
| Fault resilience | All protections (UVLO/OVP/CPUV/OCP/OTW/OTS) include fixed 5-ms auto-retry, enabling self-recovery without host intervention. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar three-phase BLDC motor driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRV8323RSRTVT | SPI-only interface; higher 10-A peak current; includes internal current sense amplifiers but requires external shunts. | Better suited for high-current (>7-A), firmware-controlled FOC systems where SPI configurability outweighs pin-count constraints. | Choose DRV8323RSRTVT when design requires dynamic register updates, advanced diagnostics, or >5-A continuous current. |
| MP6550GQZ-P | Pin-compatible 36-pin QFN; 40-V abs max; no integrated LDO; requires external 3.3-V supply and shunt resistors. | Targeted at industrial pumps with wider input range (6–36 V) and less stringent space constraints than consumer appliances. | Choose MP6550GQZ-P when operating above 20 V or when existing 3.3-V rail simplifies power architecture. |
Compared with DRV8317HREER, DRV8323RSRTVT offers greater current headroom and real-time configurability at the cost of added firmware complexity, while MP6550GQZ-P trades integration (no LDO, no shuntless sensing) for extended voltage range and simplified thermal layout.

FAQ
What is the maximum PWM frequency supported by the DRV8317HREER?
The DRV8317HREER supports PWM frequencies up to 200 kHz. This capability enables high-resolution field-oriented control (FOC) and sinusoidal commutation, reducing torque ripple and audible noise in precision BLDC applications such as laptop fans and handheld gimbals. The actual usable frequency depends on slew rate setting and thermal management - at highest slew (SLEW = AVDD), minimum pulse width is 500 ns.
How does the DRV8317HREER implement current sensing without external shunt resistors?
The DRV8317HREER integrates a precision current sense amplifier (CSA) that measures voltage drop across its internal MOSFETs' RDS(ON). It provides three analog outputs - SOA, SOB, SOC - each scaled to 0.25–2 V/A depending on the GAIN pin state. This eliminates external shunts while maintaining ±5-A full-scale range and <±5% gain error, directly supporting closed-loop current control in the DRV8317HREER-based system.
What protection features are built into the DRV8317HREER?
The DRV8317HREER includes VM under-voltage lockout (UVLO: 4.4 V), VM over-voltage protection (OVP: 22 V), charge pump UVLO (CPUV: 2.8 V), overcurrent protection (OCP: 9.5-A trip), and FET overtemperature warning (125°C) and shutdown (160°C). All protections assert the open-drain nFAULT pin and employ fixed 5-ms auto-retry - a hardware-defined behavior unique to the DRV8317HREER variant.
Can the DRV8317HREER operate from a 5-V supply?
Yes, the DRV8317HREER operates from 4.5 V to 20 V, making it compatible with 5-V systems. However, at VVM < 6 V, peak output current is limited to 3 A (vs. 5 A at ≥6 V), and RDS(ON) increases to 155–290 mΩ. The integrated 3.3-V LDO remains functional down to 4.5 V, supporting external logic and sensors without additional regulators.
What is the purpose of the MODE, SLEW, and GAIN pins on the DRV8317HREER?
These three 4-level input pins configure core functionality without SPI: MODE selects 6x/3x PWM commutation mode; SLEW sets output slew rate (13.75–320 V/µs) to balance EMI and switching loss; GAIN selects current sense amplifier gain (0.25/0.5/1/2 V/A) to match motor current range. Each pin accepts four distinct voltage levels tied to AGND, 47-kΩ divider, Hi-Z, or AVDD - enabling robust hardware-only setup in the DRV8317HREER.
