What are the key features of DRV8860APW?
- 8-channel open-drain low-side driver with 350 mA maximum output per channel for relay, solenoid, and LED matrix control
- Schmitt-trigger inputs provide hysteresis noise immunity, rejecting slow or noisy logic transitions from microcontroller GPIO
- Integrated overcurrent, undervoltage lockout, and thermal shutdown protection prevent damage without external protection components
- Serial SPI interface enables all 8 outputs to be controlled with only 3 GPIO lines, conserving microcontroller pins
- 16-pin HTSSOP package with exposed pad for improved thermal dissipation in high-channel-count load switching designs
What is DRV8860APW used for?
The DRV8860APW is designed for industrial and building automation systems requiring simultaneous control of multiple inductive loads such as relays, solenoids, and stepper motor windings through an SPI interface from a single 16-pin package. Its 8 open-drain outputs at up to 350 mA each make it suitable for LED matrix drivers, valve actuators, and printer head arrays where centralized control reduces wiring complexity. The integrated thermal and overcurrent protections simplify safety design in unattended industrial equipment operating across -40°C to +85°C environments.

Frequently Asked Questions
How many output channels does the DRV8860APW provide, and what is the maximum current per channel for driving relay coils?
The DRV8860APW provides 8 independent open-drain output channels, each rated for up to 350 mA continuous current, sufficient to directly drive most 5 V and 12 V relay coils without external transistors. With all 8 channels switching simultaneously, the device's integrated thermal shutdown engages when the die temperature exceeds the thermal protection threshold, preventing damage from overload conditions.
How does the SPI interface of the DRV8860APW reduce GPIO usage compared to individual transistor-based low-side drivers?
The DRV8860APW uses an SPI serial interface to control all 8 outputs with only 3 microcontroller GPIO lines (SCLK, SDI, CS), compared to 8 separate GPIO pins required for 8 discrete transistors. This saves 5 GPIO pins per device and allows daisy-chaining multiple DRV8860APW ICs on the same SPI bus to expand output count to 16 or 24 channels with no additional GPIO overhead.
What protection features does the DRV8860APW include, and how do they simplify safety design for industrial relay control systems?
The DRV8860APW integrates overcurrent protection, undervoltage lockout, and thermal shutdown in a single 16-pin package. These features eliminate the need for external fuses, TVS diodes, and temperature sensors per output channel. In an 8-relay industrial panel with inductive flyback voltages of up to 60 V, the integrated protections contain fault conditions autonomously, reducing system-level protection component count by approximately 16 to 24 discrete parts.
In a PCB layout with inductive load switching, how does the HTSSOP-16 exposed pad of the DRV8860APW help manage thermal dissipation?
The exposed thermal pad on the underside of the HTSSOP-16 package provides a direct low-resistance thermal path from the die to the PCB copper pour, reducing junction-to-board thermal resistance compared to standard TSSOP packages by approximately 30% to 50%. When switching 8 channels at 200 mA each with a 1 Ω on-resistance, the total power dissipation is approximately 320 mW, which the exposed pad transfers to the PCB without requiring an external heat sink.
