Abstract
A power management system () comprising a power generator () for providing a supply signal (Vchg) to a load (), a floating controllable bi-directional current sensor (N) coupled via a first connection () to the power generator and via a second connection () to the load () for detecting a positive current (pos) flowing from the power generator () to the load () and a negative current (neg) from the load () to the power generator (). In accordance with the invention, the floating controllable bi-directional current sensor (N) is controlled by a current management block () coupled to a control terminal (G) of the floating controllable bi-directional current sensor (N) and to the first and second connections () for controlling an equivalent voltage between the first connection () and the second connection (), for providing a first current (Ipos), which is proportional with the positive current (pos), and for providing a second current (Ineg), which is proportional with the negative current (neg).
