Power Connectors
The DRV88xx Customer EVM offers access to VM (Motor Voltage) power rail via a terminal block (J1). A
set of test clips in parallel with the terminal block allows for the monitoring of the input power rail.
User must apply VM according to datasheet recommended parameters.
NOTE:
VDD for logic and microcontroller is derived from USB interface.
1.2
Test Stakes
Every pin on the DRV88xx device has been brought out to a test stake. A label on the silkscreen identifies
each signal.
For those pins that change functionality depending on device flavor, a table is provided with corresponding
function name on its particular column.
