TEXAS INSTRUMENTS
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 Green product and no Sb/Br Motor Type: Stepper No. of Outputs: 4Outputs Output Current: 1.5A Output Voltage: - Driver Case Style: HTSSOP No. of Pins: 48Pins Supply Voltage Min: 8V Supply Voltage Max: 32V Operating Temperature Min: -40°C Operating Temperature Max: 85°C Packaging: Each Product Range: - Automotive Qualifications Standard: - MSL: MSL 3 - 168 hours Supply Voltage Range: 8V to 32V SVHC: No SVHC (15-Jun-2015) Find similar products grouped by common attribute
