摘要： A brown-out-reset circuit having programmable power and response time characteristics. These characteristics may be programmed over an n-bit wide bus for 2n different characteristics ranging from very low power consumption and slower response time to very fast response time and higher power consumption. A serial one wire bus may be used instead of the n-bit wide bus.

摘要： An integrated circuit device inductive touch analog front end (AFE) excites selected ones of a plurality of inductive touch sensors, measures voltages across the coils of the plurality of inductive touch sensors, and provides analog output signals representative of these coil voltages. A physical displacement (touch) to the inductive sensor causes the inductance value of the inductive touch sensor to change with a corresponding change in a voltage across the coil of the inductive touch sensor. A digital processor controls selection of each one of the plurality of inductive touch sensors and receives the respective analog output voltage signal from the inductive touch AFE. When a sufficient change in the coil voltage is determined by the digital processor, that inductive touch sensor is assumed to have been actuated and the digital processor takes action based upon which one of the plurality of inductive touch sensors was actuated (touched).

摘要： An enhanced complementary waveform generator (ECWG) generates two complementary pulse width modulation (PWM) outputs determined by rising and falling event sources. In a simple configuration of the ECWG, the rising and falling event sources are the same signal which is a PWM signal having the desired period and duty cycle. The ECWG converts this single PWM input into dual complementary PWM outputs. The frequency and duty cycle of the dual PWM outputs substantially match those of the single input PWM signal. Blanking and deadband times may be introduced between the dual complementary PWM outputs, and the dual complementary PWM outputs may also be phase delayed.
