Abstract
A lubricant dispenser has at least one lubricant reservoir, an electromechanical drive which acts on at least one actuation element for discharging lubricant from the lubricant reservoir, a battery which provides a battery voltage, and a control circuit-board assembly which has at least one main circuit board having an electronic circuit assembly including at least one central microcontroller and additional electronic functional components as well as conductor tracks. The electronic circuit assembly is subdivided into a plurality of circuit islands in each of which the maximum current flowing within the circuit island in question is limited.
