Motor chip


Chip Introduction

The SS6810R is a dual very low power motor drive integrated chip driven by PWM current.

The SS6810R has two H-bridge drives with a maximum output of 40V at 1A. The input interface adopts the drive mode of Pala-IN, and the current attenuation mode can be selected as fast attenuation, slow attenuation and mixed attenuation, and the ratio of fast attenuation and slow attenuation can be set arbitrarily to control the motor drive more smoothly and efficiently. In addition, operating from a single power supply simplifies system-level setup.

Available in an ETSSOP20 173mil package, the SS6810R offers improved thermal performance, Rohs compliance, and a 100% leadframe free leadframe.
