    The motor is working and draws 100 mA but as said the chip draws 48 mA in rest..this is a bit much to let it work on batteries.
    disconnecting the motor changes nothing in power consumption at rest.
    i don't know how much the chip is allowed to draw in rest.
    tried also a second chip and this one draws 50mA!

    any idea's?

    You could fit a switch to remove power when it's not in use, or a relay.
