PT5135 Quad DMOS Full Bridge PWM Motor Driver DESCRIPTION The PT5135 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 2 A and 32 V. The PT5135 includes fixed off-time pulse width modulation (PWM) current regulators, along with 2- bit nonlinear DACs (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 mixed decay mode for reduced audible motor noise, increased step accuracy, and reduced power dissipation. FEATURES 32 V output rating 4 full bridges Dual stepper motor driver High current outputs 3.3 and 5 V compatible logic supply Synchronous rectification Internal under-voltage lockout (UVLO) Crossover-current protection Holding current Switching Low profile QFN package Internal synchronous rectification control circuitry is provided to improve power dissipation during PWM operation. Protection features include thermal shutdown with hysteresis, under voltage lockout (UVLO) ,crossover current protection and holding current switching. Special power up sequencing is not required. The PT5135 is supplied in two packages, with exposed power tabs for enhanced thermal performance. One is a 6 mm x 6 mm, 36 pin QFN package with a nominal overall package height of 0.90 mm. Another is a 7 mm × 7 mm 48 pin LQFP. Both packages are lead (Pb) free, with 100% matte tin lead frame plating.
