A method for configuring a program-controlled integrated circuit which contains default configuration data and includes input/output lines connectable to at least one external source of configuration data, the method including: a) determining whether an external source of configuration data is connected to the input/output lines; b) in response to a determination that an external source of configuration data is connected to the input/output lines, configuring the integrated circuit in accordance with that configuration data from that source; and c) in response to a determination that an external source of configuration data is not connected to the input/output lines, configuring the integrated circuit in accordance with the default configuration data. An application specific integrated circuit containing circuit units which must be configured in accordance with configuration data, the circuit including: external connection lines for connecting the circuit to an external source of configuration data; a first non-volatile memory portion storing default configuration data; and a second non-volatile memory portion storing a control program which is operative for selecting configuration data from among configuration data stored in a connected external source connected to the external connection lines and the stored default configuration data.

An apparatus for sensing the rotation of a brushless DC fan includes the fan and a sense/driver circuit and a capacitance. The sense/driver circuit is coupled to the fan to receive a sense input signal including a fluctuating electrical effect caused by fan commutation events. The sense/driver circuit processes the sense input signal to generate a sense output signal indicative of fan operation. The sense/driver circuit includes an integrated circuit. The integrated circuit includes a sense input pin, a ground return pin, a driver circuit, an integrated filter portion, a filter pin and a level detecting circuit. The capacitance is coupled to the filter pin to provide a filter with the integrated filter portion. The driver circuit includes a control terminal, a first current handling terminal coupled to the sense input pin and a second current handling terminal coupled to provide a ground return pat. The integrated filter portion includes a filter input coupled to at least one of the first and second current handling terminals of the driver circuit, and a filter output for providing a filter output signal to the level detecting circuit.

In the preferred embodiment, the outputs of a plurality of analog signal generators are connected to a single wire (the analog bus). Each analog signal generator is addressable by a unique code provided to its respective address input terminals. A host controller selectively addresses only one of the analog signal generators such that an output of only one of the analog signal generators is applied to the analog bus at a time. In this manner, a single wire may be used to transmit a plurality of analog signals to a receiver. In one embodiment, the receiver is a MUX having an output connected to an ADC.

A temperature-to-voltage converter includes a first circuit for developing a signal having a positive temperature coefficient and a second circuit for developing a signal having a voltage offset and a negative temperature coefficient. The converter also includes an adder circuit configured to subtract the negative-temperature-coefficient signal from the positive-temperature-coefficient signal. The resulting difference signal is a low voltage that exhibits linear temperature-to-voltage conversion, allowing the converter to be powered by a low operating voltage.

The present invention uses a reference voltage that varies within a Pulse Width Modulation (PWM) cycle to generate the PWM signal. This allows for stability in the feedback of Constant On-Time (COT) control for buck controllers when low Equivalent Series Resistance (ESR) capacitors are used as the output capacitor. The reference voltage is adjusted using features of a PWM cycle in a voltage mode without using external inductor current information.
