  • System to control the output current with temperature through a controllable current limiting circuit
    Patent number: 6307726
    Abstract: A controllable current limiting circuit (30) that, when used with a low precision current limiting circuit (10), will limit the current of the output driver transistor M1 to a relatively flat response over a broad temperature range. The current is limited by setting the voltage across a resistance, R1, to a certain value. To overcome temperature induced variations in this voltage, the compensation circuit (20) generates a current that varies with temperature. This current is injected into a terminal of the resistance, R1. This current is generated in such as a manner to ensure that the current flowing in the output driver transistor M1 is relatively constant over a wide temperature range.
