DRV8860PWR 8-Channel Serial Low-Side Motor Driver TSSOP-16

The DRV8860PWR is a high-performance 8-channel protected low-side driver from Texas Instruments, designed for precision control of unipolar stepper motors, DC motors, relays, and solenoids. Identified by the silk screen code 8860 and housed in a thin TSSOP-16 package, this chip integrates eight NMOS FETs with built-in inductive catch diodes to safely handle voltage spikes from inductive loads. Its primary advantage is a serial interface that allows for daisy-chaining multiple devices, significantly reducing the number of microcontroller pins required for complex systems. With a wide operating voltage range of 8V to 38V and built-in diagnostic features—including overcurrent, open-load, and overtemperature detection—the DRV8860PWR is a robust solution for industrial automation, robotics, and automotive circuit applications.

Features:

• 8-Channel Low-Side Driver: Independent control of eight NMOS FETs with up to 560mA peak output.
• Serial Interface (SPI): Simplifies wiring and supports daisy-chaining for multiple driver control.
• Integrated Inductive Diodes: Built-in protection for driving motors, relays, and other inductive loads.
• Configurable PWM: Supports adjustable energizing and holding duty cycles to minimize heat generation.
• Full Diagnostic Suite: Reports overcurrent, open load, and thermal faults for each individual channel.
• Compact TSSOP-16 Footprint: Thin profile and small 5x6.4mm size ideal for high-density PCBs.
