Abstract: 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.

Abstract: The present disclosure relates to simplified monitoring and transmission of a binary switch position by means of coded switching, in which corrections caused by different pulse edge delays are eliminated. According to the disclosure, an auxiliary voltage which is to be transmitted when the switch position is closed is coded using two identical pulse edges of two different pulses, that is to say using either the two connection edges or the two disconnection edges of the two pulses.

The two pulses mentioned can be repeatedly generated inside a basic period, which is independent of the auxiliary voltage, and have, for distinguishing purposes, a connection duration or pulse length which is different but is independent of the auxiliary voltage.
