Productoverzicht

The DRV8834PWP is a 2.2A Low Voltage Stepper with 32-step indexer or dual brushed DC motor driver (indexer or PH/EN Ctrl), provides a flexible motor driver solution. The device has two H-bridge drivers and is intended to drive a bipolar stepper motor or two DC motors. The output driver block of each H-bridge consists of N-channel power MOSFETs configured as an H-bridge to drive the motor windings. Each H-bridge includes circuitry to regulate or limit the winding current. With proper PCB design, each H-bridge of the DRV8834 can driving up to 1.5A RMS (or DC) continuously, at 25°C with a VM supply of 5V. The device can support peak currents of up to 2.2A per bridge. Current capability is reduced slightly at lower VM voltages. Internal shutdown functions with a fault output pin are provided for over-current protection, short-circuit protection, under-voltage lockout and over-temperature. A low-power sleep mode is also provided.
  • Dual H-Bridge current-control motor driver
  • Capable of driving two DC motors or one stepper motor
  • Built-in indexer logic with simple STEP/DIRECTION control and up to 1/32-step micro stepping
  • PHASE/ENABLE control, with ability to drive external references for >1/32-step micro stepping
  • Dynamic tBLANK and mixed decay modes for smooth micro stepping
  • PWM winding current regulation and limiting
  • Green product and no Sb/Br

Toepassingen

Industrial, Computers & Computer Peripherals, Security, Imaging, Video & Vision, Automotive, Robotics, Motor Drive & Control

Waarschuwingen

Device has limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
