DRV8317HREER

Overview

The DRV8317HREER is a three-phase PWM motor driver from Texas Instruments designed for brushless DC (BLDC) motors. It integrates three half-bridge circuits with N-channel power MOSFETs, supporting supply voltages from 4.5 V to 20 V. The device features integrated three-phase current sensing without external resistors and includes a built-in 3.3 V LDO regulator providing up to 80 mA. It supports configurable 6x or 3x PWM control schemes for sensorless or sensored field-oriented control (FOC), sinusoidal, or trapezoidal control. The H-revision utilizes pin-based configuration for simplified implementation.

Feature Summary

• Integrates three half-bridge drivers with low on-resistance MOSFETs for efficient three-phase BLDC motor control
• Provides integrated three-phase current detection eliminating the need for external sense resistors
• Includes an internal 3.3 V low-dropout regulator capable of sourcing up to 80 mA for auxiliary loads
• Supports configurable PWM modes and slew rates to enable FOC, sinusoidal, or trapezoidal control algorithms

Applications

• BLDC motor modules in home appliances
• Robot vacuums and robotic systems
• Drone and handheld gimbal motors
• Computer and server cooling fans
• Pumps in dishwashers and washing machines

Procurement Notes

Verify the specific suffix 'HREER' corresponds to the pin-configurable variant rather than the SPI-configurable 'S' version. Confirm the package type matches the required PCB footprint. Ensure the operating voltage range aligns with the system's 2S to 4S battery or fixed rail requirements. Check for automotive qualification if the application requires AEC-Q100 standards, as standard versions may differ.

Selection Notes

Select this component when a simplified hardware configuration is preferred over SPI programming. The H-revision allows setting PWM mode, slew rate, and gain via physical pins, reducing microcontroller GPIO usage. Choose this part for applications requiring integrated current sensing to reduce bill-of-materials complexity. Consider the 5 A peak current capability and 130 mΩ typical RDS(ON) for thermal management in compact designs.

Part Context

The DRV8317 series represents Texas Instruments' solution for compact, high-performance three-phase motor drives. The H-revision specifically targets cost-sensitive and space-constrained applications by removing the SPI interface requirement. It complements other TI motor drivers by offering integrated protection features such as UVLO, OVP, OCP, and thermal shutdown within a small surface-mount package.

Replacement Considerations

• DRV8317SREER: Identical electrical performance but uses SPI interface for configuration instead of pins
• DRV8313PWPR: Lower current capability (2.5 A peak) and different packaging; suitable for smaller motors
• DRV8311HRRWR: Similar functionality but may require verification of specific pinout and configuration differences

FAQ

How is the DRV8317HREER configured?

The H-revision is configured using external hardware pins to set PWM mode, slew rate, and current detection gain, unlike the S-revision which uses an SPI interface.

Does the DRV8317HREER require external current sense resistors?

No, the device integrates three-phase current detection internally, eliminating the need for external shunt resistors.
