The device improves system reliability and efficiency while maintaining high motor performance in industrial, medical and consumer applications, such as textile manufacturing, pumps, light industrial automation and printers.
The DRV8818 features typical R DS(ON) of 150 milliohms, low-side, and 220 milliohms, high-side, improves efficiency and reduces ambient and board temperatures for improved system reliability.
The device’s configurable motor uses flexible decay modes and timing parameters to reduce audible noise and vibrations to improve system stability and performance. The DRV8818’s integrated indexer simplifies current regulation, enabling full, half, quarter and one-eighth microstepping, for a smoother motion profile.
The device offers advanced on-chip protection, including over-current, over-temperature, shoot-through and under-voltage lock-out increases system reliability and manufacturing yields. The device is compatible with the existing 1.9-A DRV8811 for lower-current systems, enabling current scalability with a single common design.
The DRV8818 motor driver is available today in a 10-mm x 6-mm HTSSOP package for a suggested retail price of $2.25 in 1,000-unit quantities.
