a _{1. A maximum ESR of 100m at motor switching frequency is assumed. The series resistance of the input supply (VDD, VDDP) should be}
v ^{maximum 50m and capable of delivering at least 1W of power. ESR information for C2 is still missing.}
ill ^{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
t _{designer can implement an external switch to power off the ASIC completely when the motor is not moving: the SQUIGGLE® RV motor holds its}
G ^{position with the power off.}
