The DRV8811 provides an integrated stepper motor driver
solution for printers, scanners, and other automated equipment applications. The device has two
H-bridge drivers, as well as microstepping indexer logic to control a stepper motor.
The output driver block consists of N-channel power MOSFETs configured as full H-bridges
to drive the motor windings.
A simple STEP/DIR interface allows easy interfacing to controller circuits. Step mode
pins allow for configuration of the motor in full-step, half-step, quarter-step, or eighth-step
modes. Decay mode and PWM off time are programmable.
Internal shutdown functions are provided for over current protection, short circuit
protection, under-voltage lockout and overtemperature.
The DRV8811 is packaged in a PowerPAD
28-pin HTSSOP package with thermal pad (Eco-friendly: RoHS and no Sb/Br).
