It has built-in diodes to clamp turn-off – Integrated Inductive Catch Diodes transients generated by inductive loads, and can be used to drive unipolar stepper motors, DC motors, – Serial Interface relays, solenoids, or other loads. – Open/Short Load Detection (DRV8860 only) The PWP package can supply up to 330 mA × 8 – Configurable 100% Output Timing channel and The PW package can supply up to 200 – Configurable PWM Duty Cycle mA × 8 channel continuous output current. A single • Continuous Current Driving Capability channel can deliver up to 560 mA continuous output current. – 560 mA (Single Channel on) PW and PWP – 200 mA (8 Channels on) PW A serial interface is provided to control the DRV8860 output drivers, configure internal setting register and – 330 mA (8 Channels on) PWP read the fault status of each channel. DRV8860 – Support Parallel Configuration devices can be daisy-chained together to use a single • 8 V to 38 V Supply Voltage Range serial interface. Energizing-time and holding-PWM- Duty cycles are configurable through serial interface • Input Digital Noise Filter for Noise Immunity as well. These functions allow for cooler running than • Internal Data Read Back Capability for Reliable always-on solutions. Control Internal shutdown functions are provided for • Protection and Diagnostic Features overcurrent protection, short-circuit protection, – Overcurrent Protection (OCP) undervoltage lockout, and overtemperature. – Open Load Detection (OL) DRV8860A does not include open load detection. Fault information for each channel can be read out – Overtemperature Shutdown (OTS) through serial interface and indicated by an external – Undervoltage Lockout (UVLO) fault pin. – Individual Channel Status Report Device Information(1) – Fault Condition Alarm PART NUMBER PACKAGE BODY SIZE (NOM) 2 Applications TSSOP (16) 5.00 mm × 6.40 mm DRV8860 HTSSOP (16) 5.00 mm × 4.40 mm • Relays, Unipolar Stepper Motors DRV8860A TSSOP (16) 5.00 mm × 6.40 mm • Solenoids, Electromagnetic Drivers (1) For all available packages, see the orderable addendum at • General Low-side Switch Applications the end of the datasheet. • LED driver with dimmer functionality (DRV8860A) 4 Simplified Schematic 1 An IMPORTANT NOTICE at the end of this data sheet addresses availability, warranty, changes, use in safety-critical applications, intellectual property matters and other important disclaimers.
