Patent ID: 8030952

Claim:
An electronic device, comprising: a semiconductor substrate having a plurality of semiconductor devices forming a functional circuit, the semiconductor substrate being a semiconductor chip substrate of the electronic device structured as an integrated circuit (IC); an integrated temperature sensor integrated on the semiconductor substrate; a power dissipation circuit formed on the semiconductor substrate in electrical isolation from the functional circuit; a comparator on the semiconductor substrate, the comparator arranged to compare an output of the integrated temperature sensor with a desired temperature value; a timer circuit, on the semiconductor substrate, electrically connected to the power dissipation circuit and the comparator for enabling the power dissipation circuit for a predetermined time period if the comparator shows the output of the integrated temperature sensor being lower than the desired temperature value, the timer circuit including a setting to control the comparison of the output of the integrated temperature sensor with the desired temperature value; and a memory disposed on the semiconductor substrate such that the desired temperature value is stored in the memory as part of a non-constant time dependent temperature profile stored in the memory.
