SLRS065A –SEPTEMBER 2013–REVISED NOVEMBER 2013

8 Channel Serial Interface Low-Side Driver

Check for Samples: DRV8860

FEATURES

APPLICATIONS

•

8-Channel Protected Low-side Driver

•

Relays

Unipolar Stepper Motors

–

Eight NMOS FETs with Overcurrent

Protection

•

Solenoids

–

Integrated Inductive Catch Diodes

Open/Short Load Detection

Electromagnetic Drivers

General Low-side Switch Applications

Configurable 100% Output Timing

Configurable PWM Duty Cycle

DESCRIPTION

The DRV8860 provides an 8-channel low side driver

with overcurrent protection and open/shorted load

detection. It has built-in diodes to clamp turn-off

transients generated by inductive loads, and can be

used to drive unipolar stepper motors, DC motors,

relays, solenoids, or other loads.

•

Continuous Current Driving Capability

–

560mA (Single Channel on)

280mA (Quad Channels on)

200mA (Oct Channels on)

Support Parallel Configuration

DRV8860 can supply up to 200mA × 8 channel

continuous output current. The current driving

capability increased with lower PWM duty cycle. A

single channel can deliver up to 560mA continuous

output current. Refer to the OUTPUT CURRENT

RECOMMENDATION section for details.

•

8V to 38V Supply Voltage Range

Input Digital Noise Filter for Noise Immunity

Internal Data Read Back Capability for Reliable

Control

•

Programmable Current Profile

A serial interface is provided to control the DRV8860

output drivers, configure internal setting register and

read the fault status of each channel. Multiple

DRV8860 devices can be daisy-chained together to

use a single serial interface. Energizing-Time and

Holding-PWM-Duty cycles are configurable through

serial interface as well. These functions allow for

lower temperature operation rather than traditional

always-on solutions.

–

Configurable 100% Output Timing. Fast

Activation of Solenoid.

–

Configurable PWM Duty Cycle in Chopping

Mode. Reducing Power Consumption and

Thermal Dissipation in Hold-mode of

Solenoid.

•

Serial Interface

Daisy Chain Connection

–

Internal shutdown functions are provided for over

current protection, short circuit protection, under

voltage lockout, and over temperature. DRV8860 can

diagnosis the open load condition. Fault information

for each channel can be read out through serial

interface and indicated by an external fault pin.

•

16-pin TSSOP Package

Protection and Diagnostic Features

–

Overcurrent Protection (OCP)

Open Load Detection (OL)

Over-Temperature Shutdown (OTS)

Under-Voltage Lockout (UVLO)

Individual Channel Status Report

Fault Condition Alarm

The DRV8860 is packaged in a 16 pin TSSOP

package (Eco-friendly: RoHS and no Sb/Br).
