LV8416CB-TE-L-H

Overview

The LV8416CB is a monolithic integrated circuit designed for driving two-phase hybrid stepper motors. It operates as a chopper driver with an internal power MOSFET bridge, supporting both full-step and half-step drive modes. The device features a wide supply voltage range of 5V to 30V and can deliver up to 2A peak output current per phase. Key functional blocks include a PWM constant current control circuit, a step signal input buffer, and protection circuits for overcurrent and thermal shutdown. It utilizes a small SSOP-16 package.

Feature Summary

• Integrates a dual H-bridge power stage with internal MOSFETs for direct motor connection
• Supports selectable full-step and half-step operation modes via mode select pin
• Incorporates automatic current decay detection for stable chopper operation
• Includes built-in thermal shutdown and overcurrent protection mechanisms

Applications

• Office automation equipment such as printers and copiers
• Industrial servo systems and positioning stages
• Medical diagnostic devices requiring precise motion control
• Security systems including access control locks and cameras

Procurement Notes

Verify the specific suffix (e.g., TE-L-H) against the manufacturer's official datasheet to confirm tape-and-reel packaging specifications and lead-free compliance status. Ensure that the ordering part number matches the exact electrical characteristics and pinout defined in the latest revision of the component documentation to avoid integration errors.

Selection Notes

Select this component when a compact solution for driving small to medium-sized two-phase stepper motors is required. It is suitable for applications needing moderate torque and speed where external power transistors are undesirable. Consider the thermal performance requirements based on the expected load current and ambient temperature conditions within the final assembly.
