Data Sheet - Application Information
8 Application Information
The NSD-2101 is designed to drive one SQL-RV-1.8 SQUIGGLE® RV motor or one UTAF motor. Recommended external components are as
follows:

1. A maximum ESR of 100mΩ at motor switching frequency is assumed. The series resistance of the input supply (VDD, VDDP) should be
maximum 50mΩ and capable of delivering at least 1W of power. ESR information for C2 is still missing.
New Scale offers a convenient MC-33DB-RV evaluation board which includes the components, along with input and motor connectors, to take
full advantage of the NSD-2101 ASIC.
The XPD input can be used to place the ASIC in stand-by mode for minimal current consumption when the motor is not moving. Alternatively, the
designer can implement an external switch to power off the ASIC completely when the motor is not moving: the SQUIGGLE® RV motor holds its
position with the power off.
