Abstract
A power circuit having a reverse battery protection feature, a current sensing feature and a temperature sensing feature employs a MOS gated power semiconductor device or other resistive device in the forward current path of a power stage. An information converting device converts analog information indicative of at least one of the current flowing through the resistive device and a signal from a temperature sensing device into a digital signal for delivery to a microprocessor.
