Abstract: A circuit comprises a plurality of electronic components integrated on a substrate, and a trim arrangement arranged to provide trim data to a respective electronic component of the plurality of electronic components. The electronic components are programmable such that the electronic components are enabled to be assigned desired properties. The trim arrangement comprises a first trim data source providing a first trim data set represented by a first number of bits, and at least one second trim data source providing a second trim data set representing an offset from the first trim data set. The second trim data set is represented by a second number of bits. The second number is less than the first number. At least one of the plurality of electronic components is provided with a trim data set formed from the first and second trim data sets such that the at least one of the plurality of electronic components is enabled to adjust its properties based on the trim data set.

Abstract: A method in charging a battery powered device (10) having a built-in charge control circuit (13) controlled by the device, and an apparatus for working the method, including said device. The device including the battery (11) is connected to a battery charger (17), and initially when the battery voltage is too low to initiate normal charging of the battery over the charge control circuit, the battery is connected to the battery charger via a current generator (25) which is switched off when the battery voltage has increased to a level which is high enough to support normal charging of the battery over the charge control circuit.
