Abstract: A control circuit for controlling current of batteries at the end of the charging phase, especially for lithium batteries, including an input/output circuit, placed between a battery charger and a battery, and an output stage, including two transistors, wherein the resistance of one of the two transistors is modulated to increase the value of the total resistance and to cause a lower turning off current of said output stage.

Abstract: A switch-type regulator with a soft-start function having an output terminal supplying an output voltage, and including an error amplifier, having a first input receiving a constant reference voltage, a second input receiving a feedback voltage dependent on the output voltage, and supplying a compensation terminal with an error voltage correlated to the difference between the reference voltage and the feedback voltage. The error amplifier includes a differential amplifier. The regulator also includes a compensation network connected to the compensation terminal. A soft-start function is obtained exploiting the compensation network.

Abstract: A circuit (225) for controlling a battery-charger device (200) with a closed-loop architecture is proposed. The circuit includes sensing means (230) for sensing an operative quantity of the device, means (245) for alternately controlling the sensing means to track the operative quantity during a tracking phase and to hold the operative quantity during a holding phase, and driving means (240) for providing a regulation signal, for regulating the operative quantity, according to a comparison between the sensed operative quantity and a reference value; the circuit of the invention further includes means (245;485-490) for causing the driving means to hold the regulation signal during at least part of each holding phase.

Abstract: A battery-charging electronic device comprises a current generator (2) adapted to supply a charging current to a battery (3) and a controlled current edge switch having a circuit (1) for controlling the switching edges of current (IO) being flowed through a power transistor (PW). The switching edge control circuit (1) comprises: a controlled edge variable voltage generator for generating a controlled edge voltage signal (VA); a voltage/current converter (11) for converting the voltage signal (VA) to a controlled edge current signal (IR); a driver circuit (12) for the power transistor (PW) being input the controlled edge current signal (IR) to mirror, onto the power transistor (PW), an output current (IO) which is proportional to the controlled edge current signal (IR).
