Abstract: An electronic device includes a first circuit to generate an output control signal when a first voltage across a first capacitor receiving an input current exceeds a threshold voltage, in response to an input signal having a first logic level. The input current is proportional to a frequency of the input signal. A second circuit is to generate an output reset signal when a second voltage across a second capacitor receiving the input current exceeds the threshold voltage, in response to the input signal having a second logic level. A flip flop is to generate a signal output as having the first logic level in response to the output control signal, and to reset and generate the signal output as having the second logic level in response to the output reset signal.

Abstract: A voltage regulator includes a feedback regulation loop and a drive transistor configured to source current to a regulated output. A transient recovery circuit is coupled to the voltage regulator circuit and includes a first transistor coupled to source current into a control terminal of the drive transistor, wherein the source current is in addition to current sourced in response to operation of the feedback regulation loop. The first transistor is selectively actuated in response to a drop in voltage at the regulated output. The transient recovery circuit further includes a second transistor coupled to sink current from the regulated output. The sink current has a first non-zero magnitude in the quiescent operating mode of the regulator circuit. In response to an increase in voltage at the regulated output, the operation of the second transistor is modified to increase the sink current to a second, greater, non-zero magnitude.

A reference voltage is generated having a first voltage value as the reference for the control signal and having a second, higher, voltage value for use in stress testing. A clamping circuit is provided between the reference voltage and the power transistor gate to function in two modes. In one mode, the clamping circuit applies a first clamp voltage to clamp the voltage at the gate of the power transistor when the generator circuit is applying the control signal.
