Victor, NY - October 8, 2008 - New Scale
Technologies, Inc. today announced availability of the
NSD-1102 dedicated piezoelectric
motor driver ASIC for its miniature SQUIGGLE micro motors, the
world’s smallest linear motors. The NSD-1102 can drive one or two
SQL-1.8 SQUIGGLE motors from a
single 2.8 to 5.5 VDC supply. System designers can control two micro
motors independently using the ASIC’s standard I²C interface.
The new piezo motor driver is housed in a tiny 4x4mm 16-Pin QFN
package. This matches the scale of the SQUIGGLE motor itself, which
is 1.8 x 1.8 x 6 mm, facilitating integration into miniature
products such as phone cameras, medical devices, tiny optical
systems, micro-robotic instruments, and electronic locks. The
NSD-1102 driver takes full advantage of the SQUIGGLE motor
capabilities including 6 mm travel range, 0.5 micrometer resolution,
speeds greater than 7 mm/sec, and stall force of 30 grams force.
The NSD-1102 includes an on-chip DC-DC step-up converter and four
half bridge drivers to create pairs of phase-shifted square waves
with ultrasonic frequency to drive the SQUIGGLE micro motors.
On-chip registers store driver instructions. A power-down mode
provides for minimal ASIC power consumption in stand-by, or the
power can be turned off entirely and the SQUIGGLE motor will hold
its last position. The motor and drive circuit draw 100 mW to 900 mW
when moving, depending on motor speed and load.
Development suite includes reference designs, evaluation
controllers
The NSD-1102 is also available on the MC-31DB driver, a printed
circuit board which includes input/output connectors and all passive
components necessary to drive one or two SQUIGGLE motors using the
I²C interface. The ASIC and passives occupy a 6 x 9 mm footprint on
the board. The MC-31DB can be used for system evaluation, as a
reference design, or for integration into OEM systems.
The NSD-1102 is also at the heart of the full-function MC-3100
motor controller, available for users who wish to take advantage of
New Scale’s PC control software and scripting interface for easy
evaluation of SQUIGGLE motors in open-loop or closed-loop
configuration.
Pricing and availability
Engineering samples of the NSD-1102 ASICs are available now.
Contact the factory for samples and for OEM pricing.
The NSD-1102 is available for purchase in single quantity as part of
the MC-31DB driver and MC-3100 controller. A complete evaluation kit
including an SQL-1.8 motor, MC-3100 controller, software and all
connector cables is available now for $650.
