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 provides a choice of external pins (connections) that may be user selectable for coupling an external filter/stabilization capacitor to an internal voltage regulator. However, connecting the output of a internal voltage regulator to an uncharged external filter/stabilization capacitor (or to a capacitor charged to a different voltage level than the internal regulation voltage) through a low impedance path can cause the regulator output voltage to sag/spike if the internal voltage regulator tries to charge/discharge the capacitor up/down to equilibrium with the regulator output voltage. To minimize this potential sag/spike, the voltage on the external filter/stabilization capacitor may be adjusted in a controlled manner to substantially the same voltage as the voltage on the output of the internal voltage regulator, and then the internal voltage regulator is operationally coupled through a low impedance to the external regulator filter/stabilization capacitor.

摘要： A mains voltage zero-crossing detector has a constant voltage forced on an external node by driving transistor devices with appropriate control signals provided by a feedback loop around a highly power efficient class B configuration comprising an operational amplifier having single ended dual outputs and a class B control circuit. Mains power zero crossings may then be detected by monitoring the drive current of devices driven by this amplifier. Wherein Class B control and current mode detection provide accurate detection of the driven signal without depending on any voltage threshold that may depend on temperature, process fabrication and/or supply voltage.
