DRV8834RGER - TI Function Overview

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/DIRECTION 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 RDS(ON): 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
