Overview
The DRV8860PWR is an octal low-side driver manufactured by Texas Instruments, designed for stepper motor control and ignition applications. It features a serial interface for simplified connectivity. The device operates within a supply voltage range of 8 V to 38 V and supports a maximum output current of 560 mA per channel. It functions reliably across an operating temperature range from -40°C to +85°C. The component utilizes a TSSOP-16 surface-mount package and draws a typical quiescent supply current of 3 mA.
Feature Summary
- Integrates eight independent low-side drivers with a unified serial interface for streamlined control logic.
- Supports unipolar stepper motor configurations and general-purpose switching tasks through dedicated output channels.
Applications
- Unipolar stepper motor control systems
- Ignition coil driver circuits
- General-purpose low-side switching applications
Procurement Notes
Verify the specific ordering suffix 'PWR' corresponds to the TSSOP-16 package and reel packaging configuration as documented in the official datasheet. Confirm that the serial interface requirements align with the host controller's communication protocol before procurement. Ensure thermal management strategies account for the specified operating temperature limits and power dissipation characteristics inherent to the TSSOP-16 form factor.
Selection Notes
Select this component when an octal low-side driver topology is required for driving multiple loads simultaneously via a serial bus. It is suitable for designs needing high integration to reduce board space compared to discrete solutions. Consider the 560 mA output capability and 38 V maximum voltage rating to ensure compatibility with the intended load specifications and system power rails.
Part Context
This part belongs to the DRV8860 family of motor controllers and drivers produced by Texas Instruments. It is specifically engineered for applications requiring multiple low-side outputs controlled through a serial interface, distinguishing it from parallel-interface or half-bridge variants within the broader product portfolio.
Replacement Considerations
Consult the official datasheet for pin-compatible alternatives within the same family. Verify electrical parameters such as output current and voltage ratings against the original design requirements before substituting.
