NSD-2101

Technical coantmesntAsGtill valid Datasheet NSD-2101 Piezo Motor Driver ASIC for SQL-RV Series Reduced Voltage SQUIGGLE® RV and UTAF™ Motors 1 General Description 2 Key Features 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. Industry’s smallest piezo motor drive solution with direct battery drive - Wide input supply voltage: 2.3 to 5.5 VDC - 1.8 x 1.8 mm 16-ball WL-CSP or 4 x 4 mm 16-pin QFN (minimum order quantities for QFN apply) Low power consumption: - Proprietary design optimizes power usage - Hard power-down mode for lowest power consumption - Idle mode via software for reduced power while preserving frequency calibration Proprietary frequency tracking controls maximizes motor performance over a range of operating and environmental conditions Built-in oscillator; no external clock or oscillator required I²C interface ...
