New Scale offers a convenient MC-33DB evaluation board which includes these components, along with input and motor connectors, to take full
advantage of the NSD-1202 ASIC.
a _{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}
v ^{designer can implement an external switch to power off the ASIC completely when the motor is not moving: the SQUIGGLE motor holds its}
position with the power off.
