New ultra-efficient, low-voltage motor drivers for battery-powered applications

The devices are also highly integrated in an ultra-small package, reducing board space by as much as 95 percent compared to discrete implementations.

These new devices provide smooth motion profiles – on-chip 32-step microstepping indexer and advanced motion control features on the DRV8834 have minimized torque ripple for quiet, ultra-smooth motion in applications such as security video cameras, medical and office automation equipment.

They also provide extended battery life –  Low RDS(ON) of 305 milliohms and an ultra-low sleep current as low as 10 nA improves thermal performance and extends battery life in applications, such as toys, e-locks, cameras, point-of-sale printers and smart meters.

They offer a high level of integration, such as an on-chip indexer and current control loops, providing greater intelligence to reduce design complexity while minimizing microcontroller (MCU) MIPS requirements and software development, speeding time to market compared to discrete solutions.

Evaluation modules (EVMs) are available today to evaluate all three devices.
