Classification: CPC G  H | IPC G  H

Claim 7:
8. The load driving circuit as claimed in claim 1, wherein the load driving circuit has a first reference potential and a first power potential forming a first power potential range and a second reference potential and a second power potential forming a second power potential range smaller than the first power potential range and provided within the first power potential range,
the first output-stage transistor and the second output-stage transistor generate currents that are output respectively based on the first power potential and the first reference potential,
the detection circuit comprises a current folding part which generates, based on the second reference potential and the second power potential, a mirror current pair with respect to the currents output from the first output-stage transistor and the second output-stage transistor, and the coupling circuit, based on the second reference potential and the second power potential, generates the first to fourth currents from the mirror current pair generated by the current folding part.
