资 源 简 介
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 for each consists of N-channel power MOSFETs configured as full H-bridges to drive the motor windings.
A simple step/direcTIon interface allows easy interfacing to controller circuits. Pins allow 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).
