ABSTRACT:
A primary current circuit42that outputs a primary current IPTAT proportional to the primary coefficient of temperature, secondary current circuit43outputs a secondary current IPTAT2proportional to the Nth (N: an integer of 2 or larger) coefficient of temperature based on the primary current, constant current source41that supplies current to the primary and secondary currents, and power control switch Q11that shuts down the voltage supply based on a rise in the secondary current.
