Product Description

The DRV8821DCA is a dual bipolar microstepping-capable Stepper Motor Controller/Driver with 1/8 microstepping indexer (step/direction control). It is designed for printers, scanners and other office automation equipment applications. Two independent stepper motor driver circuits include four H-bridge drivers and microstepping-capable indexer logic. Each of the motor driver blocks employ N-channel power MOSFETs configured as an H-bridge 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 and the selection of slow or mixed decay modes. Internal shutdown functions are provided for overcurrent protection, short-circuit protection, under-voltage lockout and over-temperature.
Built-in micro stepping indexers
Three-bit winding current control allows up to eight current levels
Low MOSFET on-resistance
Internal charge pump for gate drive
Built-in 3.3V reference
Simple step/direction interface
Indexer control I/F
8 Current regulation levels
