DRV8308RHAR

Overview

The DRV8308RHAR is a three-phase brushless DC motor controller manufactured by Texas Instruments. It operates within a supply voltage range of 8.5 V to 32 V and features an output current capability of 130 mA with a quiescent supply current of 12 mA. The device is housed in a 40-pin VQFN package and supports surface mount installation. It functions as a pre-driver for BLDC motors, utilizing SPI interface communication. The component is rated for operation between -40°C and +85°C.

Feature Summary

• Integrated three-phase brushless DC motor pre-driver architecture
• Serial Peripheral Interface (SPI) control mechanism
• Built-in buck regulator functionality for internal power management

Applications

• Brushless DC motor control systems
• Motion control applications requiring low-power pre-driving
• Industrial automation components

Procurement Notes

Verify the specific suffix RHAR against the official datasheet to confirm the tape and reel packaging configuration. Ensure compatibility with the required VQFN-40 footprint during PCB layout. Confirm that the operating temperature range meets the environmental requirements of the target application before finalizing procurement.

Selection Notes

Select this component when a dedicated three-phase BLDC pre-driver with SPI interface is required. It is suitable for applications needing a 130 mA output drive capability within an 8.5 V to 32 V supply range. Consider the VQFN-40 package constraints and the -40°C to +85°C operational temperature limits during design integration.

Part Context

This part belongs to the DRV8308 series of power management ICs designed for motor control. It serves as a specialized solution for driving three-phase brushless motors, distinct from general-purpose gate drivers. The series focuses on integrated control and pre-driving capabilities rather than high-current direct switching.
