DRV8811 步进电机控制器 IC
DRV8811 描述
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 PowerPADTM 28-pin HTSSOP package with thermal pad (Eco-friendly: RoHS
and no Sb/Br).
