Quad DMOS Full Bridge PWM Motor Driver

Features and Benefits

Description

▪ 36 V output rating

▪ 4 full bridges

▪ Dual stepper motor driver

▪ High current outputs

The A3988 is a quad DMOS full-bridge driver capable of

driving up to two stepper motors or four dc motors. Each

full-bridge output is rated up to 1.2 A and 36 V. The A3988

includesfixedoff-timepulsewidthmodulation(PWM)current

▪ 3.3 and 5 V compatible logic supply

▪ Synchronous rectification

▪ Internal undervoltage lockout (UVLO)

▪ Thermal shutdown circuitry

▪ Crossover-current protection

▪ Low profile QFN package

regulators,alongwith2-bitnonlinearDACs(digital-to-analog

converters) that allow stepper motors to be controlled in full,

half, and quarter steps, and dc motors in forward, reverse, and

coast modes. The PWM current regulator uses the Allegro^®

patented mixed decay mode for reduced audible motor noise,

increased step accuracy, and reduced power dissipation.

Internalsynchronousrectificationcontrolcircuitryisprovided

to improve power dissipation during PWM operation.

Packages

Protection features include thermal shutdown with hysteresis,

undervoltagelockout(UVLO)andcrossovercurrentprotection.

Special power up sequencing is not required.

Package EV, 36 pin QFN

0.90 mm nominal height

with exposed thermal pad

Package JP, 48 pin LQFP

with exposed thermal pad

The A3988 is supplied in two packages, EV and JP, with

exposed power tabs for enhanced thermal performance. The

EV is a 6 mm x 6 mm, 36 pin QFN package with a nominal

overall package height of 0.90 mm. The JP is a 7 mm × 7 mm

48 pin LQFP. Both packages are lead (Pb) free, with 100%

matte tin leadframe plating.
