Overview
The DRV8860APWR is an octal low-side driver from Texas Instruments, housed in a 16-TSSOP package. It features a serial interface for control and fault status reading. The device supports unipolar stepper motors, DC motors, relays, and solenoids. It provides over-current protection, open/shorted load detection, and built-in diodes for transient clamping. Continuous output current is up to 200 mA per channel, with single-channel capability reaching 560 mA. Operating voltage ranges from 8 V to 38 V, with a supply current of 3 mA.
Feature Summary
- Integrates eight low-side drivers with serial interface control
- Includes over-current protection and open/shorted load detection
- Configurable energizing-time and holding-PWM duty cycles via serial interface
- Built-in diodes clamp turn-off transients from inductive loads
Applications
- Driving unipolar stepper motors
- Controlling DC motors
- Actuating relays and solenoids
- General low-side switch applications
Procurement Notes
Verify the specific suffix APWR against the official datasheet to confirm pinout and thermal characteristics. Ensure the design accounts for the 16-TSSOP package dimensions and thermal dissipation requirements. Confirm that the serial interface timing matches the controller specifications. Check for any recent Product Change Notifications regarding assembly materials or marking updates.
Selection Notes
Select this component when multiple low-side switches are required in a compact form factor. The serial interface reduces pin count compared to parallel control methods. Consider the 200 mA continuous current limit per channel for load sizing. The integrated protection features simplify system design by reducing external components for fault handling and transient suppression.
Part Context
The DRV8860 series offers octal low-side driving capabilities for general-purpose switching. The APWR variant specifically denotes the 16-TSSOP package option. This family allows daisy-chaining multiple devices for expanded channel counts using a single serial interface. Internal shutdown functions provide comprehensive protection against electrical faults.
Replacement Considerations
The DRV8860PWR is a compatible alternative within the same family, offering similar functionality in a different package configuration.
