Description:

The DRV8436 is a stepper motor driver for industrial and consumer end equipment applications. The device is fully integrated with two N-channel power MOSFET H-bridge drivers, a microstepping indexer, and integrated current sensing. The DRV8436 is capable of driving up to 1.1-A rms (dependent on PCB design)

The DRV8436 uses an internal current sense architecture to eliminate the need for two external power sense resistors, saving PCB area and system cost. The device uses an internal PWM current regulation scheme selectable between smart tune, fast, slow and mixed decay options. Smart tune decay technology automatically adjusts for optimal current regulation performance and compensates for motor variation and aging effects.

 Applications:

• Multi-purpose printers and scanners
• 3D printers and laser beam printers
• Automatic teller and money handling machines
• Textile and sewing machines
• Stage lighting equipment
• CCTV, security and dome cameras
• Office and home automation
• Factory automation and robotics
