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.

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)

The two motors can be controlled independently using a standard

I²C interface.

ꢀ

Minimum 65% efficiency (at VDD=2.8V, IOUT=25mA,

freq=2MHz)

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.

ꢀ

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

Four half bridge drivers create pairs of phase-shifted square waves

with ultrasonic frequency as required to drive SQL Series

SQUIGGLE motors.

This part supersedes and is backward-compatible with the NSD-

1102.
