Functional description

Internal circuitry is added in order to increase the accuracy of the motor current particularly

with low current levels.

2.6

VS, VSS, VRef

The circuit will stand any order of turn-on or turn-off the supply voltages VS and VSS. Normal

dV/dt values are then assumed.

Preferably, VRef should be tracking VSS during power-on and power-off if VS is established.
