    摘要: In a computer, an overload protection circuit for protecting the computer's power supply from overload over a wide ambient temperature range. The overload protection circuit, which compares two voltage signals in order to shut off the computer power supply when certain limits are exceeded, is implemented without any pots or other trim circuits. Instead, a resistive temperature device is utilized to counter the effects of increasing ambient temperature on the overload protection circuit.
