NSD-1202-ASS - Dual Piezo Motor Driver IC for SQL Series SQUIGGLE Motors, QFN16

Art.Nr.: NSD-1202-ASS

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. 

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.
