Data Sheet
NSD-1202
Dual Piezo Motor Driver IC for SQL Series
SQUIGGLE Motors
1 General Description
The NSD-1202 is a dedicated piezo motor driver ASIC capable of
driving two SQL Series SQUIGGLE motors from a single 2.8 to 5.5
VDC supply.
The two motors can be controlled independently using a standard
I2C interface.
An on-chip DC-DC step-up converter generates the high supply
voltage (24 to 40 VDC) required by the piezoelectric elements of the
SQUIGGLE motor.
Four half bridge drivers create pairs of phase-shifted square waves
with ultrasonic frequency as required to drive SQL Series
SQUIGGLE motors.

2 Key Features
Wide Input Supply Voltage Range: 2.8 to 5.5VDC
Step-up converter to generate programmable high-voltage
power supply (24 to 40V)
Minimum 65% efficiency (at VDD=2.8V, I OUT =25mA,
freq=2MHz)
4x output driver with defined rise/fall time
I2C interface
On chip registers store driver instructions
Power-down mode for minimal power consumption in stand-by
Small 4x4mm 16-Pin QFN Package
This part supersedes and is backward-compatible with the NSD-
1102.
