DRV8834PWPR

双桥步进电机或直流电动机驱动器 DUAL BRIDGE STEPPER OR DC MOTOR DRIVER

Description

The DRV8834 provides a flexible motor driver solution for toys, printers, cameras, and other mechatronic applications. 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 1.5-A RMS or DC continuously, at 25°C with a VM supply of 5 V. The device can support peak currents of up to 2.2 A per bridge. Current capability is reduced slightly at lower VM voltages.

Features

• Dual-H-Bridge Current-Control Motor Driver

   – Capable of Driving Two DC Motors or One Stepper Motor

• Two Control Modes:

   – Built-In Indexer Logic With Simple STEP/DIRECON Control and Up to 1/32-Step Microstepping

   – PHASE/ENABLE Control, With the Ability to Drive External References for > 1/32-Step Microstepping

• Output Current 1.5-A Continuous, 2.2-A Peak per H-Bridge at VM = 5 V, 25°C

• Low RDSON: 305-mΩ HS + LS

   at VM = 5 V, 25°C

• Wide Power Supply Voltage Range: 2.5 V to 10.8 V

• Dynamic tBLANK and Mixed Decay Modes for Smooth Microstepping

• PWM Winding Current Regulation and Limiting

• Thermally Enhanced Surface-Mount Package

Applications

• Battery-Powered Toys

• POS Printers

• Video Security Cameras

• Office Automation Machines

• Gaming Machines

• Robotics
