Abstract: Various embodiments described below relate to an ESD protection device that includes a voltage controlled shunt (e.g., a transistor) to selectively shunt energy of an incoming ESD pulse away from a circuit that includes a semiconductor device to be protected. In some embodiments, the ESD protection device includes a power up detection element to determine whether the circuit has powered up. If the circuit is powered up, the power up detection element prevents inadvertent triggering of the ESD protection device.

Abstract: A converter includes a switched capacitor circuit that includes at least one capacitor and a plurality of main switches to provide an output current in response to an input voltage applied to the switched capacitor circuit. The converter further includes one or more bypass transistor switches to selectively provide an additional output current. The converter includes a common controller that controls the plurality of main switches and the one or more bypass transistor switches.

Abstract: Representative implementations of devices and techniques may minimize switching losses and voltage ripple in a switched capacitor de-de converter. A digital controller is used to control switching, based on an existing load. In some examples, the digital controller may insert a dead-time phase in a switching period, which may reduce voltage ripple for a low output load current. In other examples, the digital controller may adjust the conductance of a plurality of sub-switches, where the plurality of sub-switches may include one or more sub-switches that have a higher on-resistance than other sub-switches. For example, a sub-switch may have an on-resistance that is a multiple of the on-resistance of other sub-switches.

Abstract: Representative implementations of devices and techniques minimize switching losses in a switched capacitor dc-dc converter. The slope of the charging and/or discharging phase may be modified, smoothing the transitions from charge to discharge and/or discharge to charge of the switched capacitor.
