1 General Description
In combination with the SQUIGGLE® RV or UTAF, the NSD-2101
provides the industry’s smallest piezo motor drive solution with direct
battery drive; no boost circuit required.
The NSD-2101 is a dedicated piezo motor driver ASIC capable of
driving a SQL-RV Series Reduced Voltage SQUIGGLE® RV motor
or UTAF motor from a single 2.3 to 5.5 VDC supply. The motor can
be controlled using a standard I²C interface.
The NSD-2101 uses proprietary control technology to dynamically
adjust motor drive frequency to maintain optimal motor performance
and minimal power consumption over wide temperature ranges and
operating conditions. A built in oscillator eliminates the need for an
external master clock.

... Supporting More Than Two NSD-2101s on a Single I²C Bus. To support more than two NSD-2101 drivers on the same I²C bus, the ADR pin may be used as a chip select. That is, one driver is held low by the host and on all others it is held high. The host then sends commands to the driver with ADR held low. This of course requires that there be a separate chip select line for each NSD-2101 ...

Page 16

... Directing the NSD-2101. The basic command that is sent to the NSD-2101 is the pulse count (with direction). When a non-zero value is written to registers 02 and 03 by the host microprocessor, the NSD-2101 begins generating pulses on the output pins at the interval defined by the period register (01). For each pulse, the specified pulse count is decremented ...
