描述

The NSD-2101 is a dedicated piezo motor driver ASIC capable of driving one New Scale SQL-RV-1.8 reduced voltage SQUIGGLE® RV motor or one UTAF™ piezo motor from a single 2.3 to 5.5 VDC supply. The motor can be controlled through standard I²C interface.

The NSD-2101 uses proprietary hybrid speed control technology dynamically adjusts motor drive frequency to maintain optimal motor performance and frequency tracking to dynamically minimal power consumption. Built in oscillator eliminated the need for external master clock.

It's available in 1.8x1.8mm 4x4 wafer scale package or 4x4mm 16-pin QFN package.
