DRV8860APW

Overview

The DRV8860APW is an octal low-side driver from Texas Instruments, housed in a 16-pin TSSOP package. It operates within a supply voltage range of 8 V to 38 V and supports continuous output currents up to 200 mA per channel. The device features a serial interface for control and status monitoring, enabling daisy-chaining capabilities. Internal protection mechanisms include over-current, short-circuit, under-voltage lockout, and over-temperature shutdown. It is designed for driving unipolar stepper motors, DC motors, relays, and solenoids.

Feature Summary

• Octal low-side driver architecture with integrated NMOS power stages
• Serial interface for configuration, control, and fault status reading
• Built-in transient clamping diodes for inductive load protection
• Comprehensive internal protection against over-current, short circuits, and thermal overload

Applications

• Unipolar stepper motor drive systems
• Brushed DC motor control applications
• Relay and solenoid switching circuits
• General-purpose low-side switch implementations

Procurement Notes

Verify the specific suffix 'PW' confirms the 16-TSSOP package variant rather than the PWP option. Confirm that the standard DRV8860 open-load detection is excluded, as this feature is reserved for the DRV8860A variant. Ensure compatibility with system voltage ranges between 8 V and 38 V before integration.

Selection Notes

Select this component when eight independent low-side switches are required in a compact surface-mount package. The serial interface reduces pin count compared to parallel control schemes. Consider the DRV8860A if open-load detection functionality is necessary for the application, as the standard APW version lacks this diagnostic capability.

Part Context

This part belongs to the DRV8860 family of octal low-side drivers. It shares the core architecture with variants like the DRV8860PWR but differs in packaging and specific diagnostic features. The PW suffix denotes the TSSOP-16 form factor, distinguishing it from the larger PWP package options available within the same product line.

Replacement Considerations

The DRV8860APWR serves as a direct pin-compatible replacement offering the same electrical characteristics in a different package format.
