DRV880x DMOS Full-Bridge Motor Drivers Features 3 DescriptionThe DRV880x providesa versatile motor driver H-Bridge Motor Driver solution witha variety of capabilities. The device• Low RDS(on) MOSFETs (0.4-Ω Typical) containsa full H-bridge which can be usedto drivea• Low-Power Sleep Mode brushed DC motor, one windingofa stepper motor, other devices suchas solenoids.A simple PHASE-• 100% PWM Supported ENABLE interface allows easy interfacing to• 8-Vto 36-V Operating Supply Voltage Range controller circuits.• Thermally Enhanced Surface-Mount Package The output stages use N-channel power MOSFETs• Protection Features: configured as an H-bridge. The DRV880xis capable– VBB Undervoltage Lockout (UVLO) of peak output currents upto ±2.8A and operating
voltages up to 36 V. An internal charge pump– Charge Pump Undervoltage (CPUV)
generates the needed gate drive voltages.– Overcurrent Protection (OCP) low-power sleep modeis provided which shuts– Short-to-Supply Protection down internal circuitry to achieve a very low– Short-to-Ground Protection quiescent current draw. This sleep mode can be set– Overtemperature Warning (OTW) usinga dedicated nSLEEP pin. Overtemperature Shutdown (OTS) Internal protection functions are provided for– Fault Condition Indication Pin (nFAULT) undervoltage, charge pump fault, overcurrent, short-
to-supply, short-to-ground, and overtemperature.
Fault conditions are indicated through the nFAULT
2 Applicationspin.• Printers
The DRV880x is packaged ina 16-pin WQFN• Industrial Automation package with PowerPAD™ (Eco-friendly: RoHS& no• Robotics Sb/Br).
