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.

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.
