A current measuring circuit for a PWM driver. The current measuring device measures
the high side and low side currents of a PWM driver circuit before the currents
reach the driver. A first measuring circuit measures the high side of the circuit
and a second measuring circuit measures the low side of the circuit. The second
measuring circuit also receives a signal from the first measuring circuit containing
the current measurement measured by the first circuit and the second circuit then
adds this current to the second circuit current and transmits a signal of the summed
currents to a receiving device.
