Method for determining the current consumption of an active load and associated electronic device

One embodiment of the invention relates to a method for determining the current consumption of an active load and an associated electronic device. A first resistor (R1) special for measuring low current and a second resistor (R2) special for high current are coupled in series with a voltage source . When the current drawn by the active load exceeds a current threshold corresponding to a maximum admissible voltage drop across the first resistor (R1), a stabilization current is delivered to the node (NC) common to the series coupled first and second resistors in such a way as to stabilize thevoltage on the terminals of the active load at a threshold value. In the presence of such a current in excess of the current threshold, the current consumed by the active load is measured from the voltage drop across the second resistor (R2). 本发明的实施例涉及用于确定有源负载的电流消耗的方法及相关电子电路。专用于测量低电流的第电阻器(R1)和专用于测量高电流的第二电阻器(R2)被布置成与电压源(S1)串联。当由有源负载汲取的电流超过对应于该第电阻器(R1)的端子上的最大可允许电压降的电流阈值时，将电流递送至这两个电阻器的公共节点(NC)，其方式为使得该有源负载的端子上的电压稳定在阈值处。并且，当存在这种
